One of the last species I found was this Pacific Forktail. Not much to say about it: Ischnura cervula, the Pacific forktail, is a species of narrow-winged damselfly in the family Coenagrionidae. It is found in Central America and North America.
Now, of much greater importance and interest is the Duck Weed. Lemnoideae is a subfamily of flowering aquatic plants, known as duckweeds, water lentils, or water lenses. They float on or just beneath the surface of still or slow-moving bodies of fresh water and wetlands. Also known as bayroot, they arose from within the arum or aroid family (Araceae) - flic.kr/p/2m51zRE.
These plants have a simple structure, lacking an obvious stem or leaves. The greater part of each plant is a small organized "thallus" or "frond" structure only a few cells thick, often with air pockets (aerenchyma) that allow it to float on or just under the water surface. Depending on the species, each plant may have no root or may have one or more simple rootlets.[2]
Reproduction is mostly by asexual budding (vegetative reproduction), which occurs from a meristem enclosed at the base of the frond. Occasionally, three tiny "flowers" consisting of two stamens and a pistil are produced, by which sexual reproduction occurs. Some view this "flower" as a pseudanthium, or reduced inflorescence, with three flowers that are distinctly either female or male and which are derived from the spadix in the Araceae.
The flower of the duckweed genus Wolffia is the smallest known, measuring merely 0.3 mm long. The fruit produced through this occasional reproduction is a utricle, and a seed is produced in a bag containing air that facilitates flotation.
One of the more important factors influencing the distribution of wetland plants, and aquatic plants in particular, is nutrient availability. Duckweeds tend to be associated with fertile, even eutrophic conditions. They can be spread by waterfowl and small mammals, transported inadvertently on their feet and bodies,[5] as well as by moving water. In water bodies with constant currents or overflow, the plants are carried down the water channels and do not proliferate greatly. In some locations, a cyclical pattern driven by weather patterns exists in which the plants proliferate greatly during low water-flow periods, then are carried away as rainy periods ensue.
Duckweed is an important high-protein food source for waterfowl. The tiny plants provide cover for fry of many aquatic species. The plants are used as shelter by pond-water species such as bullfrogs and fish such as bluegills. They also provide shade and, although frequently confused with them, can reduce certain light-generated growths of photoautotrophic algae.
For at least six years, my primary source for dragon- and damselfly photography were three places in Heather Farm, a wonderful wildlife area given to the city a century ago for the enjoyment of "all citizens." In just three years - even before Covid - it seems that our City has deemed the wildlife part of the farm as unimportant. When I visited last week after a 15 month absence, duck weed had died, water flow was nonexistent, and in three areas, reeds had taken over a most beautiful lagoon where I photographed odonata but, even more, all manner of herons, ducks, and egrets! All gone! And I mean all! Seven Canada geese and, four mallards. Can you imagine a pond that once provided me with large populations of Ringed-necked ducks (flic.kr/p/2kNy5VY), Snowy egrets, *breeding* Double-crested cormorant colony, and a field of wild mustard that was the courtship, mating and nesting grounds for Redwinged blackbirds and a hunting ground for mated Red-shouldered hawks. All gone! And for what? An ill-conceived "community garden" that few were interested in, and now is a field of boxed weeds, fences that keep wildlife out, and cost more than enough to have maintained the two ponds (one a small lake), a stream, the lagoon, the mini-waterfall that was a breeding ground for the dragonflies, and six islands on which plants that were not native were planted and which died in less than 18 months and cost something like $7k each. They are still there. I saw one duck and dead plants. In four years, we've lost a treasure, a place where wild river otters and muskrat would nest during the summer (flic.kr/p/HagXWg). The two established nests are either in disrepair or have been torn down by the city. But basically, it's almost like planned neglect. I have a thousand images taken at Heather Farm from 2008 to 2019. There's nothing left to enjoy in the wild state. No hawks (flic.kr/p/2eqZiAj) breed there anymore, and they are neither fish nor vegetation to sustain such a wonderful population of wildlife ... even wildflowers. (The rose garden is kept up because it's a revenue source: wedding take place there, but I wonder how long that will occur since the devastation is just outside the rose garden gates.)
As this is my most viewed / commented / faved pic I'll tell you a little about it:
I had a vacation in Tiberias (on the shore of the Sea of Galilee) and noticed a lovely but lonely early morning swimmer having the whole pool just for herself. This opportunity shot was taken standing on the 8th floor's porch. Two seconds later her friend joined in and all that perfect relaxation went into shambles...
Trimmed only. No PS, coloring, additives or preservatives...! ;-)

Conwy Morfa. These concrete Barrels were part of the flotation Jettys that were used to float the Mulberry Harbours that were built here that were used in the WW2 D-Day landings in Normandy. Designed by Bangor-born Welsh engineer, Hugh Iorys Hughes.
Watching the Otters in Morro Bay Harbor. The one holding all four paws up is not playing to the crowd but is drying and warming its paws. These are the only areas that are not covered by the Otters marvelous fur. So, we often see them holding them out of the cold Ocean water.
The one seen doing the constant rolling is really not playing(mostly) but is trying to add air to his fur for extra flotation and extra warmth.
The Coast Guard boat...well, I don't really know what they are doing, just that it is not in an area they usually frequent.
All in Morro Bay Harbor on a fine day.

my sister came back from dallas for the weekend, and we went shopping for organizing items. thus, the new shelves. they're slightly too big for the space i have them in, but it's the only space available. yes, i have the electrical box or whatever you call it in my room, how nice. you also can't cover it up. i got to spend a lot of time at the pool with my new flotation device. it was a good day, i'd say.
Depending on the format of which your seeing this you will either wonder how the block floats or you'll see the light stand, dam you blacks!!!! I so hate how different my images look on different monitors.
Well i started out by trying to light paint a cube with a lazer but ended up here!
No adjustments were made in ps to improve the hiding of the stand
Strobist.... sb28@1/8 gridded snoot from left at cube, sb28@1/16 through softbox precisely positioned to illuminate me but not my front, 200w strobe red gel on min at lower back wall for bottom silhouette
This is a bit of a rough idea but I've over run my allotted time to play :(
These fortress-like stone foundations are the remains of Broken Hill Proprietary Limited (BHP)’s concentration mills that operated from 1894 to 1897. The company’s first concentration mill was built on the east side of the lode in 1889. Concentration is the process of separating valuable metals or minerals from the raw material, in this case ore. The first mill was closed due to subsidence.
A gravity mill with a capacity of 10,000 tons of ore per week was erected here in 1897. The mill produced high-grade lead, but millions of tons of zinc-rich waste product, or tailings, were dumped.
In 1904, the flotation process was added to the plant. Flotation involves crushing the ore to separate valuable minerals and gangue (mined rock that is not ore) components, pulping the particles of ore with water, and then separating the specific mineral. It operated until 1927 and was demolished in 1940.

The Block 10 mine, one of the original BHP leases, was floated as the BHP Block 10 Co. Ltd in 1888. A concentration mill was erected at the mine in the 1890s to treat sulphide ore. Underground subsidence seriously affected the mill and, as a result, a new mill was erected on this hill in 1903, about 600 metres from the mine.
An aerial ropeway, the first at Broken Hill, was completed in 1904. This transported broken ore from the mine to a large storage bin above the mill. The mill cost £50 000 and could treat 3500 tons of ore per week.
The mine produced 2.5 million tons of ore and paid £1.5 million in dividends up to 1923 when it and the mill closed and were purchased by BHP. The mine was reworked by Broken Hill South Ltd between 1946 and 1960. Much of the mine site is now covered by overburden dumps from modern open-cut operations.
The concrete foundations on site are the remnants of the Block 10 concentration mill erected in 1903. The mill, designed by Captain John Warren and containing many of his inventions, was the first all electric mill in Broken Hill.
The aerial ropeway delivered broken ore from the mine to a storage bin above the mill. Broken ore was fed to crushing rolls and then passed to cylindrical trommels and hydraulic classifiers for sizing. Subsequent treatment consisted of wet concentration by jigs, Wilfley tables and vanners. These relied on specific gravity to separate the heavier lead and silver minerals from the zinc minerals. The resultant concentrate contained about two-thirds of the lead and one-half of the silver in the original ore, but very little zinc.
Flotation units were added to the mill in 1910 to produce a zinc concentrate from the tailings. Combined gravity-flotation concentration mills were standard at Broken Hill until after 1930 when the first all-flotation plants were installed.

Yabba Creek is a major tributary of the Mary River. The Yabba Valley is a green valley with native vine forests, sclerophyll forests and plantations of native Araucaria (hoop pine) clothing the plateaux, escarpments and slopes of the upper valley, and grazing and agriculture on the floor of the lower valley.
In the early 1860s, timbergetters came to the valley to fell red cedar, pine and hardwood logs which were floated downstream to sawmills at Maryborough (and later Gympie) or allowed to go to Great Sandy Straits and Hervey Bay where ships would collect the logs and transport them to distant ports.
Here on the Yabba at "Imbil" station, the Yabba had a 5km meander associated wit several minor flood channels across the pocket. This resulted in logs from upstream being stranded on the pocket during freshets and floods, so some of the men resolved to blast the neck of the meander such that floods would take the shortcut, erode a new cutting and allow their logs to pass uninhibited by the meander. The former pocket, then became Imbil Island.
As rail replaced floods to carry the logs to sawmills downstream, agriculture replaced grazing and Imbil Island became a productive agricultural area. During droughts, the water the farmers on the island needed for irrigation, no longer flowed around the old meander. Representation was made resulting in the construction of this weir in 1953, which raised the water level by 900mm ensuring a flow of water around the old meander.
Today the weir ensures an aquatic playground for children with kayaks, canoes or other flotation implements whilst proving a large area for swimming and diving. A large and popular riverside campground is found just upstream of this site.

I was setting up to shoot the bluffs across the river when this very enthusiastic group of revelers drifted around the bend. At this point, the water was pushing them toward my side of the river, but they needed to be on the opposite side for the take out, just another 200 yards down the river. Furious activity ensued, but they were still having fun.
Some of these people were using flimsy flotation devices, but no one was in danger of going under.
The Dewey Bridge is approximately 25 miles upriver from Moab. This portion of the Colorado River is generally calm, like the stretch shown here.
Here's something a little different for you all! I decided to take the van out for a test run to White Pocket, which if you're familiar can only be accessed via a 4wd road that has very soft, deep sand with hills! I aired down my tires to maximize flotation and am happy to say that I made it no problem, which has to be the first 15 passenger van that's been out there! There were no clouds so I stuck around to do some night shooting. This was taken during astronomical twilight to get some light on the foreground and some blue in the sky.
I used a fog filter for the sky to make the bright stars pop and a long exposure for the foreground. I was forced to shoot with my backup camera since the X-T1 is in for repair (don't drop your camera kids), so this was taken with the Fuji X-E1, that's right the low end camera that I picked up for $275 used. Not freaking bad. Talk about a cheap way to get into nightscapes, combine this with the Rokinon 12mm f/2.0 for $300 and you're good to go for sub $600!
I have also updated my recommended night photography gear page www.exploringexposure.com/night-photography/
If you would like to go to White Pocket I have a tour next year www.exploringexposure.com/2015-photography-workshops/pari...
Guillaume Daniel (G.D.) Delprat, after whom this shaft was named, was a Dutch-Australian metallurgist and mining engineer. An astute businessman, Delprat was Broken Hill Proprietry Limited’s ( BHP) General Manager from 1899 to 1921. He played an important part in the perfecting of a technique that came to be known as the (C.V.) Potter-Delprat flotation process; it revolutionized sulphide ore treatment and brought enormous profits from the metal content of millions of tons (tonnes) of formerly useless tailings.and a developer of the flotation process, which entails separating valuable minerals from gangue (mined rock that is not ore) with water.
The Delprat shaft was sunk in 1900. In 1952, the original wooden headframe was replaced by the present steel structure, and an electric winder replaced a steam engine. The early steam engines used to power mining machinery in the early twentieth century were powered by boilers fuelled by local firewood. Timber was also cut for use in buildings and headframes.
The shaft was closed to mining by the time MMM (Mining for Metal and Minerals) ceased operations in August 1976. It became a tourist mine in 1977, and its closure in 2007 was due to nearby remnant mining operations by CBH Resources.

Summer Snowflake
Leucojum aestivum, commonly called the summer snowflake, giant snowflake, Loddon lily (see River Loddon § Loddon lily) and rarely snowbell and dewdrop among others, is a plant species widely cultivated as an ornamental. It is native to most of Europe from Spain and Ireland to Ukraine, with the exception of Scandinavia, Russia, Belarus and the Baltic countries. It is also considered native to Turkey, Iran and the Caucasus. It is naturalized in Denmark, South Australia, New South Wales, Nova Scotia and much of the eastern United States.
Description
Leucojum aestivum is a perennial bulbous plant, generally 35–60 cm (14–24 in) tall, but some forms reach 90 cm (35 in). Its leaves, which are well developed at the time of flowering, are strap-shaped, 5–20 mm (0.2–0.8 in) wide, reaching to about the same height as the flowers. The flowering stem (scape) is hollow and has wings with translucent margins. The pendant flowers appear in late spring and are borne in umbels of usually three to five, sometimes as many as seven. The flower stalks (pedicels are of different lengths, 25–70 mm (1.0–2.8 in) long. The flowers are about 3–4 cm (1.2–1.6 in) in diameter and have six white tepals, each with a greenish mark just below the tip. The black seeds are 5–7 mm (0.2–0.3 in) long.
After flowering, the fruits develop flotation chambers but remain attached to the stem. In England, it has been recorded that flooding causes the stems to break and the fruits to be carried downstream and stranded in river debris or on flood-plains. The bulbs can also be transported during heavy floods and deposited on river banks.
Downloaded, edited & uploaded by me because it’s rare, looks cool, is enlightening/informative and sheds a little more light on the enigmatic artist “Todd”. In the process, confirming my assumption of him/her being a Northrop Corporation artist.
Doing my insignificant part in preserving “space” history, primarily the imagery, and its rich (to me) legacy. And, it’s a WIN.
Based on the overall appearance of the capsule, that of Big Joe 1, I'm assuming this work to be ca. 1959.
And I love the Piasecki (Vertol) H-21 helicopter moving in. Piasecki...who knew...did you?!? I didn't.

Flat surf, overcast sky, no crowds, flotation devices, surfboards, Surf Rescue IRB, shallows, shore break, Pacific Beach. What could go wrong on the Gold Coast this afternoon?
A resident of Kampong Phluk, Cambodia, returning home with a bounty of three packages of Asian noodles. Notice that the flotation device near the right side of his body is made of empty water bottles that have been bound together with a piece of fishing net. Also I noticed as he was coming ashore that he had to negotiate the mangrove roots with bare feet.
