In 1762, Silas Deane came to Wethersfield to teach and study law. He met Mehitable Webb, Joseph's widow, and became her legal and business advisor. They married in 1763, and had one son, Jesse, in 1764. Having ìarrivedî socially, Silas' constructed his own mansion, conveniently next door to his Webb stepfamily. The new house was very different from the rest of Wethersfield architecture, more closely resembling dwellings from the Dutch West Indies or New York, with an asymmetrical facade probably featuring a piazza, or porch. The door opened onto a spacious hallway with a grand staircase, and the best parlor contained a carved Portland brownstone fireplace. Although the piazza is gone, the staircase and fireplace remain to this day.
The Deane House was completed about 1766. Mehitable had little time to enjoy it, however, for she died in 1767. In 1769 Silas married another rich widow, Elizabeth Saltonstall Evards from New London. In 1774 Silas Deane served in the first Continental Congress, and while he was there John Adams visited Wethersfield and took tea with Mrs. Deane. In 1775 George Washington dined with Elizabeth en route to take command of the troops outside of Boston. Silas went to France in 1776 on a secret mission to secure troops, arms, and supplies for the revolutionary cause.
While he was in Paris Elizabeth Deane died, and that misfortune was compounded by accusations of mismanagement of government funds. Silas was abruptly recalled by Congress but never given a hearing to exonerate himself. Having spent his fortune in an attempt to clear his name, he sent instructions to his brother Barnabas in Wethersfield to sell all his furniture. Disillusioned and impoverished, he stayed in Europe in self-imposed exile, but in 1789 decided to return to Canada to rebuild his fortune. On board ship on the night before his departure, he died mysteriously, and is buried in England.
Stephen Chester bought the Deane House from Silas' creditors sometime after 1790. From 1800-1873 it passed through many hands until it was bought by Frances Talcott Fenn in 1874. Her son, U.S. Representative E. Hart Fenn inherited the house in 1899. Mr. Fenn and his second wife Margaret were active in the early preservation movement, and made few structural changes to the building, even going so far as to install the only bathtub in the basement! However, the house was severely damaged by fire in 1932, and the extent of the loss is unknown.
Mrs. Fenn was a Connecticut Colonial Dame, and after she inherited the Deane House in 1939 she secretly made plans to turn it over to the Society after her own death. Her gift was a very welcome surprise in 1959, completing the Museum complex of the three adjacent houses. From 1960-1974 the Colonial Dames worked assiduously on the house's restoration, and in 1964 the house was declared a National Historic Landmark. When it opened to the public in 1974, it was recognized as one of the most careful and accurate restorations undertaken in the United States.
The Long Beach Peninsula is known for its continuous sand beaches on the Pacific Ocean side, 28 miles (45 km) in extent, claimed to be the longest beach in the United States. Because of the fine beaches, it is a popular vacation destination for people from Seattle, Washington, 165 miles (266 km) distant, and Portland, Oregon, 115 miles (185 km) distant.

For Macro Monday - November 12 2018 - "Green"
Tacks made of fish heads and fins! Stuck in green glitter paper.
Compared to the red and cream crap in the background (I've never driven an ex Glasgow panoramic that didn't leak to the extent you wondered if it had mains plumbing without a tap on the end; and those ex Blackburn East Lancs bodies where you could change the beam from dip to full by kicking the back of the headlight at your feet...) , this Ailsa was the equivalent of an Aston Martin in terms of refinement. One of three bought from Clydeside 2000, it was the first to come off the road. A regular on the Ballingry to St Columbas run, I've never been on a bus yet that could romp up Station Brae in Lochgelly with a standing load quite like this beast. Yee-ha!!

Inle Lake is a freshwater lake located in the Nyaungshwe Township of Taunggyi District of Shan State, part of Shan Hills in Myanmar (Burma). It is the second largest lake in Myanmar with an estimated surface area of 44.9 square miles (116 km2), and one of the highest at an elevation of 2,900 feet (880 m). During the dry season, the average water depth is 7 feet (2.1 m), with the deepest point being 12 feet (3.7 m), but during the rainy season this can increase by 5 feet (1.5 m).
The watershed area for the lake lies to a large extent to the north and west of the lake. The lake drains through the Nam Pilu or Balu Chaung on its southern end. There is a hot spring on its northwestern shore.
In June 2015, it becomes the Myanmar's first designated place of World Network of Biosphere Reserves. It was one of 20 places added at at the Unesco's 27th Man and the Biosphere (MAB) International Coordinating Council (ICC) meeting.

St Laurence’s is a characteristic Anglo-Saxon building: tall and narrow with small windows. The extent and richness of its decoration, however, are rare, perhaps suggesting it was designed partly for the relics of Æthelred’s brother Edward the Martyr, which were housed with the nuns at Shaftesbury. Some time later the church, being no longer required, was lost amidst other buildings and only came to notice again in the nineteenth century.
ive been seeing a lot strange things on flickr. a lot of hate-directed photos. and messages about the content now on flickr. i think most of you know what i mean. if not, let me explain. i was reading the other day someones opinion about photos posted by members only for fame or popularity. and now they "hate" it and want to rebel against it. i can agree to some extent. there can be some phonies out there, who like to post odd things. but who are you to say its not art? I appreciate what Duchamp was trying to say when he created his lovely urinal piece. However, seeing the messages made me evaluate myself and what I post. I don't post things to gain views or see how many times I can get on explore. Those are all nice things, and i appreciate feedback, etc, but thats not my main goal. I post things with substance and meaning for MYSELF, in hopes that it can open the eyes of others. I just wanted to clear that up. I'd like to know what you think, if you have an opinion on the craze on flickr!
i wanted to pay tribute to my "set to sea" post-it note picture :] so i brought them back. and plastered my wall in them! sorry grandma. also created a mess with paint on my body.

"Macro Mondays " On a Coin"
This coin is a $2.00 Canadian coin......we call the "Toonie." This particular coin was one of a special edition produced as a remembrance of the 100 anniversary of the Battle of Vimy Ridge in WWII. The regular "Toonie" has a Polar Bear embossed in the gold coloured centre.
I chose a brass button to suggest the uniform buttons of the soldiers.

A text, in english, from Birdlife International:
Justification
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence 30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but this species is described as 'common' (Stotz et al. (1996).
Trend justification
This species is suspected to lose 15.9-17.6% of suitable habitat within its distribution over three generations (12 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.

Pouco Preocupante
The industrial area is already gone...but at this moment I'm working on a small new layoutfor the @llmtcnl ! It will include a simpler track plan and more regular scenery unrelated to trains, such as this typical Dutch house!
The window frames are inspired by @pieterpostlego but modified. It captures the details and scale of window frames very well in my opinion. The masarderoof is seen all around the Netherlands as it provides more space on the upper floor. It'snot perfect, but since I already spent ages on this it's alright. The small extention on the groundfloor is also typical Dutch and called the "klompenhok". Though not the main entrance, the entrance to the klompenhok was almost always open for friends and family.
This build turned out really good and my intention is to take more time for every part of the layout, as my last layout felt a bit rushed in some areas.
Let me know what you think, I'm curious to hear your opinions! :)
For Macro Monday ........Hearts
These hearts are cookie cutters from a set that come in a flat round tin container. The smallest is about 1 inch by 1 inch. The bottom of the tin has a red paper lining that reflected up to give the colour!
Ever notice how if you have 36 exposures you never reach the end of the film, but if you have 24, you're at the end before you know it? Film extensions would solve this particular dilemma.

The Pannonian Plain is a large plain in Central Europe that remained when the Pliocene Pannonian Sea dried out. It is a geomorphological subsystem of the Alps-Himalaya system.
The river Danube divides the plain roughly in half.
The plain is divided among Austria, Bosnia and Herzegovina, Croatia, the Czech Republic, Hungary, Romania, Serbia, Slovakia, Slovenia and Ukraine.
The plain is roughly bounded by the Carpathian mountains, the Alps, the Dinaric Alps and the Balkan mountains.
Although rain is not plentiful, it usually falls when necessary and the plain is a major agricultural area; it is sometimes said that these fields of rich loamy loess soil could feed the whole of Europe. For its early settlers, the plain offered few sources of metals or stone. Thus when archaeologists come upon objects of obsidian or chert, copper or gold, they have almost unparalleled opportunities to interpret ancient pathways of trade.
The precursor to the present plain was a shallow sea that reached its greatest extent during the Pliocene, when three to four kilometres of sediments were deposited.
The plain was named after the Pannonians, a northern Illyrian tribe. Various different peoples inhabited the plain during its history. In the first century BC, the eastern parts of the plain belonged to the Dacian state, and in the first century AD its western parts were subsumed into the Roman Empire. The Roman province named Pannonia was established in the area, and the city of Sirmium, today Sremska Mitrovica, Serbia, became one of the four capital cities of the Roman Empire in the 3rd century.
My edit (old slide) on LSL Ayr Extention tour how the photographers images may have looked back in the day when these beautiful locomotives were a common sight on the WCML.
86101 was one of three test-bed locomotives converted in the early 1970s from standard Class 86s to trial traction equipment for the upcoming Class 87s. Fitted with a Class 87-type transformer and bogies, the 86/1s saw front-line use on West Coast Main Line services until the late 1990s.
Purchased in 2005, restoration began in 2006, and the loco was subsequently returned to mainline condition. 86101 became the first preserved AC electric locomotive to operate on the main line on 15th March 2007, and has operated on railtours and in regular passenger service.
The loco was named "Sir William A Stanier FRS" at Liverpool on 27th October 1978, after much lobbying by the Loco Club of Great Britain, and retained the name until early 2005 when the plates were removed for safe keeping.
86101 was sold to Locomotive Services Limited (LSL) on 5th November 2019.
Before knowing the weather condition of the Himalayan region we should understand its geography. The Himalayan region covers an area of 2,250 km with an average width of 200 km.
The forest belt of the Himalayan region consists of Oak, Rhododendron, Birch, Pine, Deodar, and Fir. And the monsoon season in this region lasts for mid June till the end of September. The Himalayas influences the meteorological conditions in the Indian subcontinent to the south and in the Central Asian highlands to the north to a great extent. It acts a climatic divider circulating the air and water system to a great extent. Because of its altitude and location it blocks the passage of the cold winds coming from the north to the Indian sub continent thereby making India's climate much more moderate. It also influences the rainfall pattern in India. The combined effect of rainfall, latitude and altitude largely influences the forests belts in the Himalayan region. The rainfall is mostly recorded during the monsoon time of June to September but it decreases as you travel from east to west. The snow-capped ranges of the Himalayas stretch 2, 250 km from the Namcha Barwa to Nanga Parbat on the Indus. The range extends from east to west up to central-Nepal and then takes a southeast to northwest direction.

Wave-driven patterns left to dry in the exposed muck along the shore of the Great Salt Lake, Utah, USA, near the Saltair concert venue. The lake is so shallow that the extent of it ebbs and flows radically, and we get these wonderful mud ripples for hundreds of meters away from whatever the current "shoreline" is at any given time. Hold your nose from the aroma and lose yourself in pattern bliss. This image was a quick pause, compose and snap whilst rushing to the water's edge to catch my solstice pix.

The extent of what I can see after an hour with the retinal specialist.
It's always a long day after getting refracted. And I still haven't seen the regular optometrist about new glasses yet. I really have to find one that will work on Tuesdays and Wednesdays pretty soon, because I get no sick leave for medical appointments.
A bit of insanity, too. I was considering going to the nursery while dilated, but by the time my appointment was over, it was ninety-six degrees outside. I settled for lox and bagels instead. That much I could handle with dilated eyes and air conditioning.
I'm still impressed with my senioresque buddy Ben and, to a lesser extent, myself, for managing to climb down to this vantage point. The walking path and stairs were covered in ice. Normally, I wouldn't risk falling and breaking something while trying to get to the lower portions of this area, but as I shot a few photos from the upper deck, perfectly happy with where I was, Ben was busy testing the (very much frozen) waters, so to speak. Like an unsupervised chi-, no, 57 year old, he wandered off, doing a penguin walk on the ice and holding onto the guard rail. He did this three times, getting further down the path each time before returning to me and talking about how bad the conditions are. He still urged me to try to go down, so I did. We both went down into the gorge, valley, ravine, whatever and didn't manage to kill or injure ourselves. We even met another photographer down there! In fact, a number of people slip, slip, slide!-ed their way down there to get photos. Sure, seeing other people do it stole some of our own glory, but it was nice to conquer the negative voices that usually keep me in safer places...with less wonderful views.

The fountain was created by the Florentine sculptor Francesco Camilliani in 1554. In 1573, don Luis's financial problems reached such an extent that he decided to sell the fountain. The vice-king of Sicily at that time was the brother of don Lus don García de Toledo, and G. de Toledo was the mediator between the quarreling brother, on the one hand, and the Senate of Palermo, on the other. On May 26, 1574, the fountain arrived in Palermo in a disassembled form for 644 details, and then was assembled under the leadership of Camillo Camilliani. Some of the sculptures were beaten, two remained in Florence and are now in the Bargello Museum, something else was taken by don Luis to Naples, so the Pretoria Palermo fountain turned out to be a little poorer than itself, but in a Florentine form.

Deutschland - Baden-Württemberg - Kaiserstuhl
Schelinger Matten
The Kaiserstuhl (German: [ˈkaɪzɐʃtuːl], lit. "Emperor’s Chair") is a range of hills in the state of Baden-Württemberg in southwest Germany with a maximum height of 556.6 metres (1,826 ft). It is of volcanic origin and located in the southwest of the state in the counties of Emmendingen and Breisgau-Hochschwarzwald. In terms of natural regions it is considered to be a part of the Upper Rhine Plain.
Name
The name "Kaiserstuhl" is believed to refer to King Otto III, who held court near Sasbach on 22 December 994. From then on, the whole hill range was called the Königsstuhl – the King’s Chair. In May 996, Otto III was crowned Emperor and the King’s Chair eventually became the Emperor’s Chair – "Kaiserstuhl". Reliable sources mention the name Kaiserstuhl only as early as 1304 and historians thus suppose that the term Kaiserstuhl was not coined until the 13th century.
Geography
Location
The Kaiserstuhl is situated in South Baden, mainly in Breisgau-Hochschwarzwald county or district. However, the smaller northern part belongs to Emmendingen. Within the Upper Rhine Plain it is situated about 16 km northwest of the city of Freiburg, right next to the eastern bank of the Rhine and a short distance west of the Dreisam. It reaches up to 377 metres above the level of the Rhine downstream (179.5 m a.s.l.) from the weir close to Burkheim.
At its greatest extent, from the Michaelsberg near Riegel in the northeast, to the Fohrenberg, by Ihringen in the southwest, the Kaiserstuhl is about 15 km long. Its maximum width is about 12.5 km.
Hills
The hills of the Kaiserstuhl include the following (sorted by height in metres above sea level):
Totenkopf (556.6 m), 1.9 km east of Bickensohl; with the Vogtsburg 1 telecommunication tower and Neunlinden observation tower
Eichelspitze (521.3 m), 2.8 km northwest of Bötzingen
Katharinenberg (492.4 m), 1.3 km southeast of Amoltern
Bisamberg (469.0 m), 1.2 km south of Amoltern
Staffelberg (446.0 m), 1.5 km northwest of Schelingen
Badberg (432.7 m) (protected area), 1.5 km east of Oberbergen
Holzeck (431.9 m), 1.7 km northeast of Ihringen; with tower
Hochbuck (374.8 m), 900 m south of Achkarren
Schlossberg (352.1 m), 500 m northwest of Achkarren; with Höhingen Castle ruins
Böselsberg (340.1 m), 500 m northwest of Wasenweiler
Büchsenberg (283.7 m), 1.3 km west of Achkarren
Geology
The formation of the Kaiserstuhl volcano during the Tertiary was the climax and at the same time the end of volcanic activity in the Upper Rhine Valley Rift. Volcanism started as early as the Cretaceous Period. Volcanic landforms include heavily eroded volcanic vents. The Kaiserstuhl is the only larger volcano from this period in the rift valley. Geologically the Kaiserstuhl can be divided into two parts: the sedimentary and volcanic part. Due to these peculiarities the Kaiserstuhl has been labeled one of the most important national geotopes.
Sedimentary base
The horizontal sedimentary layers forming the eastern third of the Kaiserstuhl date back to the Jurassic and the Tertiary long before the volcanic activity. Important stratigraphic outcrops include the Hauptrogenstein (local oolite) which is found mainly near the village of Riegel and the Pechelbronner Schichten (local Tertiary layers in the South German Scarplands) near Bötzingen. During the formation of the Upper Rhine Plain this part of the Kaiserstuhl sloped less in respect to its surrounding area – and thus appears as a so-called horst. In terms of its geological structure and the sequence of its escarpments, the Kaiserstuhl is comparable to the nearby Tuniberg, Nimberg and also to the Schönberg, which is situated south of the city of Freiburg.
Volcanic activity
Petrologically the volcanic Kaiserstuhl is an alkali-carbonate rock formation. The volcanic rocks making up a large part of the central and western Kaiserstuhl were the result of numerous volcanic eruptions during the Miocene, about 19 to 16 million years ago. They cover parts of the sedimentary base of the eastern Kaiserstuhl, which is why in some places changes in the base’s mineralogical composition occurred. The driving force behind this process of contact metamorphism was an increase in temperature. Due to the alternate eruption of tephra and lava flows from several vents a complex stratovolcano came into existence. Some of the rising magma solidified as volcanic intrusions below the surface – and today forms the central part of the Kaiserstuhl. Laterally rising phonolite magma also intruded into the sedimentary base of the Eastern Kaiserstuhl. Several hundred metres of the original volcano have been eroded.
Volcanic rocks
The entire volcanic Kaiserstuhl consists of rock types that contain feldspathoid minerals and olivine and are undersaturated with SiO2. Most igneous rocks at the surface are leucite-tephrites, with subordinate phonolites, limburgites, and olivine-nephelinites (at the Limberg Mountain near Sasbach), the last of which is rich in xenoliths from the Earth’s mantle. Carbonatite ignimbrite and lapilli are local peculiarities; they can be found in places in the western part of the Kaiserstuhl (Henkenberg near Burkheim, Kirchberg near Oberrotweil).
The subvolcanic and intrusive rocks of the central Kaiserstuhl are plutonic equivalents of the erupted material (essexite, carbonatite and coarse-granular phonolite). Several local terms which do not carry official status with the International Union of Geological Sciences have been used for different varieties of the intrusive rocks. Of major scientific interest is the consolidated carbonatite near Altvogtsburg und Schelingen. It is a quite rare volcanic rock, which crystallized from a carbonate magmatic melt rather than a silicate one. Given its unusual composition for an igneous rock, the magmatic nature of the carbonatite was not proposed for a long time and remained doubtful subsequently. An alternative interpretation was that it was a metamorphically altered sedimentary rock, examples of which can be found nearby. Only in the 1950s and 1960s did research prove that it was a carbonatite; one of the clues was identification of the eruptive carbonatites found in the western part of the Kaiserstuhl. The carbonatite contains the niobium rich pyrochlore; attempts to mine the carbonatite rock for niobium were carried out in the middle of the 20th century, but the amount turned out to be too small to be economical.
Minerals
For a long time the Kaiserstuhl has been known for rare minerals. Examples include the quarries at the Limberg (zeolites), Badberg (carbonatites), Orberg and Fohberg. Well-crystallized minerals can be found predominantly in clefts or cavities in the volcanic rock.
Loess
The Kaiserstuhl is today largely covered by a Quaternary loess layer, a loosely cemented sediment. It is derived from other rocks through erosion and is then transported by the wind. The loess at the Kaiserstuhl – as in all the peripheral areas of the Upper Rhine Valley – was formed during the last Ice Age. Large parts were bare of vegetation and so loess was winnowed out from the Rhine sediments. It was then deposited in the periglacial area (i.e. ice-free, but surrounded by glaciers) at the Kaiserstuhl. The major process active here was frost weathering resulting in crushed rocks. The wind blew strongly, as there was no vegetation that could have moderated it – entraining the lightest material and depositing it at obstacles like the Kaiserstuhl. Deposition took place northeast of the Kaiserstuhl, as the winds blew from the southwest.
The higher the place of sedimentation, the thinner the layer of the sedimented material is. At the Kaiserstuhl the thickness of the loess layer varies between 10 and 40 metres. There are, however, also areas in the southwest where no loess has been deposited. The Northern Limestone Alps are considered the main source of the Kaiserstuhl loess. A rust-coloured band occurs at irregular intervals. It developed as a new material and did not arrive regularly but in phases of different intensities. In a phase of weak sedimentation the material on top weathered – and the calcium carbonate was washed out. It then precipitated further down and formed a particular type of soil horizon, which contains concretions of calcium carbonate.
The Kaiserstuhl loess soils are used for intensive farming, as they offer good aeration, high water storage capacities and good mechanical qualities. Besides, as a result of farming deep narrow ravine-like paths developed.
As the loess developed over time it is, furthermore, significant for flood control. Sponge-like, it absorbs and then gently releases rainfall. This quality is however lost when bulldozers, employed to construct large terraces for viticulture, compress the loess.
Climate
General
The Kaiserstuhl is one of the warmest regions in Germany. The winters are relatively mild for the area, and the summers are warm or even hot, with possible average temperatures of over 20 °C (68 °F) in July and August. Because of its loess covered volcanic soils it is a very good wine-producing region. The climatic situation of the Kaiserstuhl is outstanding in the area. It is rain-shadowed by the Vosges Mountains, under the climatic influence of the Belfort Gap and is characterized by a drier and hotter climate, which one would rather expect not to be typical of the area. Despite this, winters remain cold and dry, and summers wet, in comparison with Mediterranean climate (which instead has a rainfall peak during winter, which can see few frost days, and a dry season in summer).
Meteorological data
The average annual temperature is 9.9 °C (49.8 °F), with 50–60 days with a maximum temperature above 25 °C (77 °F) as well as 60–70 days with a minimum temperature below 0 °C (32 °F). This illustrates a special feature of the Kaiserstuhl: it is characterized by its relatively extreme climate. The average difference between the lowest and the highest average temperatures within one year is 18.5 °C (65.3 °F). The mean precipitation at the Kaiserstuhl is approximately 600–700 millimetres (24–28 in), with about 1,720 hours of sunshine per year.
Flora and fauna
The climate of the Kaiserstuhl also explains the vast richness of thermophile flora and fauna. The Kaiserstuhl is for example one of the places with the largest variety of orchids in Europe – more than 30 species have been recorded. Among the vines wild grape hyacinths sprawl and along acclivities iris plants blossom. Furthermore, sand lizards (lacerta bilineata) and praying mantis (Mantis religiosa) live here – species which mainly occur in the Mediterranean area. (However, according to the latest research results the sand lizard presumably belongs to the allochthonous species of the European green lizard (Lacerta viridis)). The pubescent oak (Quercus pubescens) is a Xerophyte and normally only occurs in Southern Europe, but is also able to survive at the Kaiserstuhl. This species has a disjunct distribution, which means away from its normal habitat. It is a relict of a postglacial warm period where there had been a much warmer climate around the Kaiserstuhl. After the end of the warm period only the named species were able to survive. Besides there is a larger population of the May beetle (Melolontha melolontha). In spite of protests from conservationists the May Beetle is controlled by the use of insecticides.
Changes in landscape
The terrain of the Kaiserstuhl has been altered by the people living there since it was settled. The loam there is strongly susceptible to erosion as a result of soil cultivation, thus terraces had to be added, which were then mostly used as vineyards, as well as fruit growing or for other agricultural uses. As a result, the typical small "patio" hillsides and the streaked loess sunken roads typical of the region came into being.
To start with, it was for this reason that smaller terraces were merged in around 1950, this resulted in large scale reallocation, which turned parts of the original landscape completely upside down.
The phases of this reallocation were:-
Small-scale realignment between 1950 and 1960. At the same time the terrain was generally modified by manual labour with the help of in-house machines. During this time approximately 950 hectares were enclosed by the farmland consolidation authority.
Between 1960 and 1970 the loess slopes were more comprehensively modified, whereby large rectangular terraced areas with corresponding high embankments were made. The terraces were arranged with mountain like slopes so that now only the multiple slope edges are visible from the valley. About 650 hectares of the surface were styled in this way.
The plans to create large-scale terraces made between 1970 and 1976 were executed with the help of heavy machinery, changing the landscape radically. Before the original, naturally formed, depressions had still been visible in the gentle hillsides with only small terraces. Natural and man-made structures existed side by side. However, these small-scale structures were then obliterated completely. Monstrous areas resembling fortresses and entirely incongruous to the region were created. The total wine-growing area of the terraces was 630 ha. As the embankments and other areas exceeded the size of the wine-growing areas, the changes affected more than twice the newly created arable area. The land reforms of Oberrotweil-Oberberg, Ihringen-Abtsweingarten, Eichstetten-Hättlinsberg and Endingen am Kaiserstuhl-Schambach are examples of this phase.
The last phase of wine-growing land reforms was realized between 1976 and 1982. Due, in part, to protests against plans for further large scale terraces the changes were not as radical as the previous phase: the maximum height for embankments was "limited" to 10 m and their shapes were "made smooth and adjusted to the landscape" (Mayer 1986, citation translated). This procedure was, for example, applied to about 330 ha of wine-growing area in Oberbergen-Baßgeige or in Bickensohl-Herrenstück.
From 1977 on, several longer periods of enhanced precipitation caused damage to the embankments. During one week in May 1983 for example, the amount of precipitation was so large that in some areas it was equivalent to one third of the annual average, causing great damage in the modified areas.
The surfaces of the acclivities often slid off together with the vegetation. Former valleys, which had been blocked due to re-allocation, were flushed out. In some terraces dramatic shear failures developed. In addition extensive, devastating frost damage occurred; due to the incline of the mountainside at the surfaces of the acclivities, cold air pockets were formed in which the vines in bloom were frostbitten. Additionally substantial frost damage occurred in the woody part of the vines, especially in the vineyards which were situated in lower regions. In earlier times fruit had mostly been grown here but later this was changed to vineyards.
The activity of the farmland consolidation authority was narrowed to repairing and partly to rescheduling which at least was meant to correct the most severe consequences of the transformations from 1982 on.
Hiking
There are many opportunities for hiking in the Kaiserstuhl. The best known trail is the North-South Trail (check mark: blue rhomb on yellow background) from Endingen across the Katharinenberg and the Totenkopf and the Neunlinden viewing point to Ihringen. From the trail there are panoramic views over the Black Forest, the Upper Rhine Valley and the Vosges.
(Wikipedia)
Der Kaiserstuhl ist ein bis 556,8 m ü. NHN hohes, kleines Mittelgebirge vulkanischen Ursprungs in der Oberrheinischen Tiefebene. Es erhebt sich im Südwesten von Baden-Württemberg (Deutschland), in den Landkreisen Emmendingen und Breisgau-Hochschwarzwald.
Namensdeutung
Seinen Namen hat der Kaiserstuhl vermutlich von König Otto III., der bei Sasbach am 22. Dezember 994 einen Gerichtstag abhielt. Nach diesem Gerichtstag wurde das ganze Gebirge als „Königsstuhl“ bezeichnet. Nachdem Otto III. im Mai 996 zum Kaiser gekrönt worden war, wurde aus dem „Königsstuhl“ der „Kaiserstuhl“. Nachweislich belegt ist die Bezeichnung „Kaiserstuhl“ erst seit 1304. Historiker vermuten, dass der Begriff „Kaiserstuhl“ nicht vor dem 13. Jahrhundert entstand.
Geographie
Lage
Naturräumlich wird der Kaiserstuhl zum Oberrheinischen Tiefland gezählt und stellt dort die Haupteinheit 203 dar. Er befindet sich in Südbaden zum Großteil im Landkreis Breisgau-Hochschwarzwald, der kleine Nordteil gehört zum Landkreis Emmendingen.

Geologie
Die Entstehung des Kaiserstuhlvulkans im Tertiär stellt sowohl den Höhepunkt als auch den Schlusspunkt der vulkanischen Aktivität im Oberrheingraben dar. Diese begann schon in der Kreidezeit und zeigt sich in zahlreichen, heute tief erodierten Vulkanschloten. Der Kaiserstuhl ist der einzige größere Vulkan aus dieser Zeit im Bereich des Oberrheingrabens. Dieser trifft hier auf den Bonndorfer Graben, der über den Hegau zum Bodensee führt. Gegen Ende des Oligozäns drang Magma empor, erstarrte jedoch noch unter der Erdoberfläche. Erst im Miozän kam es zu einem Durchbruch und zu großflächigen Lavaströmen. Geologisch gesehen lässt sich der Kaiserstuhl in einen sedimentären und einen vulkanischen Teil gliedern. Aufgrund dieser Besonderheiten wurde der Kaiserstuhl als eines der bedeutendsten nationalen Geotope Deutschlands ausgezeichnet.
Sedimentärer Sockel
Die das östliche Drittel bildenden, nahezu horizontal lagernden Sedimentgesteine wurden lange vor der vulkanischen Aktivität zu Zeiten des Juras und Tertiärs gebildet. Wichtige aufgeschlossene stratigraphische Einheiten sind der Hauptrogenstein (hauptsächlich in Riegel) und die Pechelbronner Schichten (in der Gegend von Bötzingen). Dieser Teil des Kaiserstuhls wurde während der Entstehung des Oberrheingrabens weniger stark als seine Umgebung abgesenkt und stellt einen sogenannten Horst dar. Er entspricht im Aufbau und der Schichtenfolge äquivalenten Strukturen im näheren Umkreis, wie dem Tuniberg und Nimberg westlich sowie dem Schönberg südlich von Freiburg im Breisgau.
Vulkanismus
Petrologisch handelt es sich beim vulkanischen Kaiserstuhl um einen Alkaligesteins-Karbonatit-Komplex. Die den Großteil des zentralen und westlichen Kaiserstuhls aufbauenden vulkanischen Gesteine wurden vor rund 19 bis 16 Millionen Jahren im Miozän durch zahlreiche Vulkanausbrüche gebildet. Sie überlagern teilweise den sedimentären Sockel des östlichen Kaiserstuhls, wodurch dieser stellenweise kontaktmetamorph, das heißt durch Einwirkung hoher Temperatur, verändert wurde. Durch abwechselnde Eruption von Tephra und Lavaströmen aus mehreren Schloten bildete sich ein komplexer Schicht- oder Stratovulkan. Emporquellendes Magma erstarrte teilweise als subvulkanische Intrusion im Vulkangebäude und baut heute den Zentralkaiserstuhl auf. Lateral aufsteigende phonolithische Schmelzen drangen auch in den sedimentären Sockel des östlichen Kaiserstuhls. Bis heute wurden durch Erosion mehrere 100 m des ursprünglichen Vulkans abgetragen.
Vulkanische Gesteine
Der gesamte vulkanische Kaiserstuhl besteht aus Foid- und/oder Olivin-führenden, SiO2-untersättigten Gesteinen. Bei den Eruptivgesteinen handelt es sich zum größten Teil um Leucit-Tephrit, untergeordnet auch Phonolith, Limburgit und Olivin-Nephelinit (am Limberg bei Sasbach). Letzterer ist sehr reich an Xenolithen aus dem Erdmantel. Als Besonderheit bei den Eruptivgesteinen sind karbonatitische Ignimbrite und Lapilli zu nennen, die im Westkaiserstuhl an einigen Stellen (Henkenberg bei Burkheim, Kirchberg bei Oberrotweil) aufgeschlossen sind.
Bei den subvulkanischen Intrusionen und Ganggesteinen des zentralen Kaiserstuhls handelt es sich um die Tiefengesteinsäquivalente der Ausbruchsprodukte (Essexit, Karbonatit und grobkörnigerer Phonolith). Für verschiedene Varietäten der Ganggesteine existieren in der Literatur eine Fülle weiterer Bezeichnungen (Alvikit, Hauynophyr, Mondhaldeit, Tinguait, Monchiquit und viele andere), die aber teilweise keine allgemein anerkannten Gesteinsnamen sind. Von großem wissenschaftlichen Interesse ist der bei Altvogtsburg und Schelingen anstehende Karbonatit. Dabei handelt es sich um ein recht seltenes vulkanisches Gestein, das nicht aus einer silikatischen, sondern aus einer karbonatischen Schmelze auskristallisierte. Aufgrund dieses ungewöhnlichen Umstandes wurde die magmatische Natur des Karbonatits lange Zeit nicht erkannt oder in Zweifel gezogen. Alternative Interpretationen gingen von kontaktmetamorph veränderten Sedimentgesteinen aus, die bekanntermaßen in unmittelbarer Nähe zu finden sind. Erst in den 1950er- und 1960er-Jahren gelang es, das Gestein gesichert als Karbonatit zu identifizieren, unter anderem durch das Auffinden der eruptiven Karbonatite im westlichen Kaiserstuhl. Wegen des in ihm auftretenden Niob-Minerals Koppit wurde der Karbonatit in der Mitte des 20. Jahrhunderts versuchsweise bergmännisch abgebaut. Allerdings erwiesen sich die Gehalte als zu gering für eine Nutzung in größerem Umfang.
Minerale
Seit langer Zeit ist der Kaiserstuhl als Fundstelle für zum Teil seltene Minerale bekannt. Besondere Fundstellen sind die Steinbrüche im Limburgit des Limbergs (verschiedene Zeolithe), im Karbonatit am Badberg und Orberg (Koppit) und im Phonolith des Fohbergs und des Kirchbergs (Zeolithe, Wollastonit, Melanit). Überwiegend treten diese als Kluftminerale oder Blasenfüllungen (Mandelstein) auf.
Lössbedeckung
Der Kaiserstuhl ist heute weitgehend von einer quartären Lössschicht bedeckt. Löss ist ein Lockersediment, welches durch Erosion anderer Gesteine entsteht und durch äolischen Transport an seinen Ablagerungsort befördert wird. Der Löss entstand – wie im gesamten Randbereich der Oberrheinebene – während der letzten weitgehend vegetationsfreien Eiszeit durch Auswehung aus dem Rheinschlamm. Die Ablagerung fand im periglazialen (eisfreien, jedoch von Gletschereis umgebenen) Gebiet um den Kaiserstuhl statt. Der Hauptprozess, der in dieser Region stattfindet, ist Frostsprengung von Gestein. Da keine Vegetation vorhanden ist, die den Wind bremsen könnte, weht dieser beständig stark. Er nimmt das leichteste Material mit und lagert es an Hindernissen, beispielsweise dem Kaiserstuhl, wieder ab. Hierbei ist zu beachten, dass die Ablagerung im Lee stattfindet, im Falle des Kaiserstuhls – wo der Wind aus Südwesten wehte – also im Nordosten. Je höher der Sedimentationsort liegt, desto dünner ist die Schicht tatsächlich abgelagerten Materials. Am Kaiserstuhl liegt die Mächtigkeit der Lössschicht zwischen 10 und 40 Metern, es gibt jedoch auch Orte im Südwesten, an denen kein Löss sedimentiert wurde. Der Herkunftsort des Lösses am Kaiserstuhl lag hauptsächlich in den nördlichen Kalkalpen. Auffällig im anstehenden Löss ist ein sich in unregelmäßigen Abständen wiederholender, rostfarbener Streifen. Dieser entsteht durch die phasenweise Anlieferung neuen Materials. Während einer schwachen Sedimentationsphase verwittert das obenauf liegende Material, wobei der Kalk ausgewaschen wird. Hierbei bildet sich Lösslehm. Der ausgewaschene Kalkanteil fällt weiter unten im Bodenprofil wieder aus und bildet den sogenannten Lösskindelhorizont. Zu jedem Ausfällungshorizont gehört deshalb ein Anreicherungshorizont.
Die Lössböden des Kaiserstuhls werden agrarisch intensiv genutzt, da sie eine gute Belüftung bieten und eine hohe Wasserspeicherfähigkeit sowie mechanisch gute Eigenschaften besitzen. Außerdem sind im Zuge der landwirtschaftlichen Nutzung die sogenannten Lösshohlwege entstanden.
Der gewachsene Löss ist zudem für den Hochwasserschutz von Bedeutung, da er starke Niederschläge wie ein Schwamm aufnimmt und dann gleichmäßig wieder abgibt. Durch die Anlage von Großterrassen für den Weinbau am Kaiserstuhl wird der Löss jedoch mit Planierraupen verdichtet und verliert diese Eigenschaft.
Klima
Allgemeines
Klimatisch zählt der Kaiserstuhl zur temperaten (gemäßigten) Klimazone. Durch die in der Oberrheinebene vorherrschende Wärmebegünstigung gehört er jedoch zu den wärmsten Orten Deutschlands mit für Mitteleuropa vergleichsweise milden Wintern und warmen Sommern, die teilweise sogar Durchschnittstemperaturen von über 20 Grad in den Monaten Juli und August aufweisen können. Durch seine mit Löss bedeckten vulkanischen Böden ist er ein sehr gutes Weinanbaugebiet. Die klimatischen Voraussetzungen des Kaiserstuhls heben sich von seiner Umgebung deutlich ab. Er liegt im Regenschatten der Vogesen, im Einfluss der Burgundischen Pforte, und hat somit ein eher trockenes Klima.
Meteorologische Daten
Die Jahresmitteltemperatur beträgt 9,9 °C, wobei sowohl 50 bis 60 Sommertage als auch 60 bis 70 Frosttage zu verzeichnen sind. Dies spiegelt schon ein besonderes Merkmal des Kaiserstuhls wider, denn er zeichnet sich durch recht extreme Klimaverhältnisse aus, was sich besonders in der durchschnittlichen jährlichen Temperaturschwankung von 18,5 °C ausdrückt. Der mittlere Niederschlag auf dem Kaiserstuhl beträgt etwa 600 bis 700 mm, bei jährlich rund 1.720 Stunden Sonnenschein.
Flora und Fauna
Das Klima des Kaiserstuhls erklärt auch die große Fülle an wärmeliebender Flora und Fauna. Beispielsweise ist der Kaiserstuhl einer der Orte mit der größten Orchideenvielfalt in Europa – mehr als 30 Arten wurden registriert. Zwischen den Rebstöcken wuchern wilde Traubenhyazinthen, und an Böschungen blühen Schwertlilien. Außerdem leben hier Bienenfresser, Smaragdeidechsen und Gottesanbeterinnen (Mantis religiosa) – Arten, die ihren Verbreitungsschwerpunkt im mediterranen Bereich haben (nach neuen genetischen Studien handelt es sich bei der Smaragdeidechse allerdings um eine wahrscheinlich allochthone Population der Östlichen Smaragdeidechse). Die Flaumeiche ist ein Xerophyt und kommt sonst vor allem in Südeuropa vor, am Kaiserstuhl kann sie sich jedoch vor allem im Flaumeichenwald am Büchsenberg als Niederwald halten. Diese Arten leben in einem disjunkten Areal, also von ihrem normalen Verbreitungsgebiet abgetrennt. Dies ist ein Relikt einer postglazialen Warmzeit, zu der auch im Gebiet um den Kaiserstuhl ein deutlich wärmeres Klima herrschte. Nach Ende der Warmzeit konnten die genannten Arten nur noch am Kaiserstuhl überleben. Außerdem gibt es am Kaiserstuhl größere Populationen des Maikäfers. Die Art wurde in der Vergangenheit trotz Kritik von Umweltschützern mit Insektiziden bekämpft, so etwa im Jahr 2009. Die Aktion wurde damit begründet, dass der Maikäfer ansonsten existenzbedrohende Schäden in der umliegenden Landwirtschaft auslösen könnte.
Landschaftsveränderung
Die Oberfläche des Kaiserstuhls wurde vom wirtschaftenden Menschen seit dessen Besiedlung verändert. Da Löss infolge der Bodenbearbeitung stark erosionsanfällig ist, mussten Terrassen geschaffen werden, die meist als Rebflächen, teilweise auch für Obst- oder zum Ackerbau genutzt wurden. Dadurch entstanden schon früh die typischen kleinterrassierten Hänge, die zudem von den ebenfalls durch die „Nutzung“ entstandenen Lösshohlwegen durchzogen wurden.
Im Sinne der Flurbereinigung wurde um 1950 damit begonnen, zunächst kleinere Terrassen zusammenzulegen; dies endete in Großumlegungen, welche die ursprüngliche Landschaft in Teilbereichen völlig umgestalteten. Diese Umgestaltung begann zwischen 1950 und 1960 mit kleinräumigen Neuordnungen. Dabei wurde das Gelände meist in Handarbeit bzw. mit Hilfe betriebseigener Maschinen umgestaltet. In dieser Zeit wurden rund 950 ha von den Flurbereinigungsbehörden flurbereinigt.
Zwischen 1960 und 1970 wurden die Lösshänge umfassender umgestaltet, wobei große, tiefe und möglichst rechteckige Terrassenflächen mit entsprechend hohen Böschungen entstanden. Die Terrassen wurden mit bergseitiger Neigung angelegt, so dass jetzt vom Tal aus vielfach nur noch die Kanten sichtbar sind. Auf diese Art entstanden rund 650 ha Rebfläche.
Mit umfassendem Maschineneinsatz wurden die Großterrassenplanungen der Jahre 1970 bis 1976 umgesetzt, die das Landschaftsbild deutlich veränderten. Vor diesen Maßnahmen zeichneten sich in den sanften Hängen, deren Oberflächen von den kleinen Terrassen überprägt waren, noch die ursprünglich natürlich entstandenen Senken ab. Statt diesem Nebeneinander von natürlichen und vom Menschen geschaffenen Strukturen nehmen die Kritiker nun festungsartige und landschaftsfremde Oberflächen wahr, die eine Gesamtgröße von ca. 630 ha Rebfläche bieten. Da die Böschungen und sonstigen Flächen größer waren als die Rebflächen, erstreckte sich die Landschaftsveränderung jeweils auf mehr als das Doppelte der neu geschaffenen nutzbaren Fläche. Beispiele für diese Phase sind die Flurbereinigungen Oberrotweil-Oberberg, Ihringen-Abtsweingarten, Eichstetten-Hättlinsberg und Endingen am Kaiserstuhl-Schambach. Inzwischen war der Großteil der Lösshohlwege durch die Flurbereinigung verschwunden, die zuvor ökologische Nischen speziell für Wildbienen und Vögel gewesen waren.
Die letzte Phase der Rebflurbereinigung erstreckte sich auf die Zeit zwischen 1976 und 1982, in der unter anderem wegen der Proteste gegen die Großterrassenplanungen gemäßigt vorgegangen wurde: Die Böschungshöhen wurden auf maximal 10 m „beschränkt“, der Böschungsverlauf wurde „geschwungen angelegt und der Landschaft angepasst“. Mit diesen Verfahren wurden zum Beispiel in Oberbergen-Baßgeige oder in Bickensohl-Herrenstück rund 330 ha Rebfläche bearbeitet.
Nachdem ab 1977 durch länger anhaltende niederschlagsreiche Perioden Böschungsschäden entstanden waren, fielen in der Pfingstwoche des Jahres 1983 Niederschlagsmengen, die teilweise ein Drittel des Jahresmittels ausmachten. Diese führten in den umgelegten Gebieten zu Schäden: Die Böschungsoberflächen rutschten vielfach mitsamt der Vegetation ab, ehemalige, durch die Umlegungen verschüttete Talzüge wurden ausgeschwemmt, in einzelnen Terrassen entstanden tiefgreifende Grundbrüche. Überdies kam es in den Folgejahren zu Frostschäden. Durch die bergseitige Neigung der Terrassenoberflächen konnten sich Kaltluftseen bilden, in denen die Reben vor allem in der Blüte erfroren.[6] Außerdem entstanden, vor allem in den niedriger gelegenen Rebflächen, in denen zuvor meist Obst angebaut worden war, erhebliche Frostschäden am Holz der Rebbestände.
Die Tätigkeit der Flurbereinigungsbehörden beschränkte sich in der Zeit nach 1982 auf Reparaturarbeiten und partielle Umplanungen, die zumindest die schwersten Folgen der Umgestaltungen korrigieren sollten. Inzwischen hatte man auch begonnen, die verbliebenen Lösshohlwege als Naturdenkmale auszuweisen und sie zu schützen.
Seit 2021 wird auf einer Fläche von etwa einem Hektar Echter Lavendel und Lavandin angebaut. Dank der Wärme und der kalkreichen Böden gedeiht er gut. Zwei der vier Felder liegen in Bischoffingen, wo es auch einen Hofladen gibt und je eines in Königschaffhausen und Burkheim. Auf letzterem wachsen neun verschiedene Sorten.
Wandern
Der bekannteste und „klassische“ Wanderweg ist der Neunlindenpfad (Nord-Süd-Weg); er ist einer von acht Themenpfaden und führt von Endingen über den Katharinenberg und den Totenkopf mit Aussichtsturm Neunlinden nach Ihringen. Von den Wegen bieten sich vielerorts Ausblicke auf den Schwarzwald, die Rheinebene und die Vogesen. Auch der Querweg Schwarzwald–Kaiserstuhl–Rhein führt über den Kaiserstuhl.
Als Wissenschaftlicher Lehrpfad wurde 1977 der Limberg-Weg angelegt. Er umfasst 90 Stationen zu den Themen Geologie und Mineralogie, Geschichte, Naturschutz und Landschaftspflege, Forstwirtschaft, Wein- und Obstbau, Rheinbau und Wasserwirtschaft, sowie Landeskunde.
Die acht Themenpfade wurden 2007 mit einer Gesamtlänge von 140 km eröffnet und in das bestehende Wanderwegenetz des Schwarzwaldvereins (Markierung: gelber Rhombus auf weißem Hintergrund) integriert. Dabei wurde das Wanderwegenetz mit 430 neuen Wegweisern ausgeschildert. Große Tafeln mit einer Übersichtskarte und mit Standortinformationen sind an zentralen Punkten wie zum Beispiel an Bahnhöfen in den von den Themenpfaden verbundenen oder durchlaufenden Ortschaften aufgestellt. Jeder Themenpfad ist durch eine eigene Farbe und ein dem Namen entsprechendes Symbol auf den Eingangsportalen und den Wegweisern optisch gekennzeichnet. Weitere 120 kleinere Thementafeln erläutern entlang der Wanderwege lokale Besonderheiten. Örtliche Pfade, wie zum Beispiel der Brunnenpfad (7 km) in Bötzingen, wurden in das neue Netz der Themenpfade integriert.
Die acht Themenpfade wurden 2010 durch den Kaiserstuhlpfad ergänzt, der als Prädikatswanderweg das Gütesiegel „Qualitätsweg Wanderbares Deutschland“ erhielt. Der 21,7 km lange Kaiserstuhlpfad orientiert sich mit einigen Erweiterungen am Neunlindenpfad (Nord-Süd-Weg) und führt von Endingen durch das Erletal hoch zur Katharinenkapelle, entlang der Naturschutzgebiete Badberg und Haselschacher Buck zum Eichelspitzturm, weiter über den Vogelsang-Pass zum Neunlindenturm, durch den Lößhohlweg Eichgasse nach Bickensohl und über den Kreuzenbuck durch die Lenzengasse nach Ihringen.

The Rodenstock Rodagon 50mm f/4 enlarging lens is becoming my most versatile macro lens. The fact that it's so tiny and when mounted on extension tubes (that exactly match the diameter of the lens barrel !) it's quite thin and can get close without touching and disturbing the environnement !
Although there are some light leaks sometimes that can be annoying because they are difficult to control...
I took this photo with extention tubes and a helicoid M42/E adapter for more precision.
The Rodagon also have great colors and contrast and good sharpness !

This shows the extent of the lake flood by the Sicamous and tugs Naramata and Canadian National No. 6 in Penticton. The boardwalk past the flock of geese seen here, has been built so that emergency exit on the port side of the Sicamous can still be used.
Normally there is a path on the west side of the Sicamous out to the breakwater, and the Naramata is usually on dry land in a fenced-off enclosure. Not right now.

Wildlife photography is to a large extent about opportunities, those you seize, those you miss, those you don't even see.... Red-winged blackbirds for sure are offering plenty of opportunities on Vancouver Island for a large portion of the year. It is probably one of the first bird I photographed when I started wildlife photography a few years ago. It is ever since, probably the bird I photograph the most each year. Yet, I feel that there is always a better picture of a red-winged blackbird which needs to be taken. The temptation was great to present a "year-end exhibit" of all those red-winged blackbird pictures I have taken this year. You will be glad I refrained from it. Here are a few I like.

Beams of early evening light on Eastern Sierra aspen groves.
As I photographed here in the late afternoon I was keeping an eye on the sun as it descended toward clouds and the Sierra crest to the west. These trees are beautifully back-lit by late afternoon sun, but it looked like that light source might disappear early behind the clouds. But as it turned out, the partially blocked light created an unusual and dramatic effect as beams of light highlighted trees against the darker background.
I think that we like to flatter ourselves about our ability to find and take advantage of subjects and great light. We sure put a lot of effort into searching out visually interesting locations than then being there when the light is likely to be ideal. But in the end we are, to a great extent, at the mercy of conditions. Sometimes that is a problem, but on evenings like this one the light gods send us a gift.

Blackberry plants seem to be springing up in my garden all the time but not to the extent of the wetlands nearby where these berries are not far from ripening. I know some people go out picking the ripe berries but I always worry that they have been sprayed with weedicides at some stage. The birds do like the berries and plants have been making chemicals to deter animals from eating them for all of evolution.
