On February 11th at 2:46pm, the City of Woodstock had a structure fire at 1165 Greenwood Circle. The city was being covered by fire departments from across the county due to Woodstock Fire/Rescue FF/PM Mike Wurtz's funeral. Huntley Chief, McHenry Truck, Union Engine, Wonder Lake Engine, Cary Ambulance, and Hebron/Alden/Greenwood Ambulance all responded to the fire. The fire was reported to have started in the bedroom leaving the residence inhabitable.
Woodstock, Illinois
Article from the Northwest Herald:
WOODSTOCK – Two residents were displaced after a fire started in their townhouse Tuesday afternoon.
Around 2:45 p.m., a neighbor reported smoke coming from the home at 1165 Greenwood Circle in Woodstock. When firefighters arrived flames were coming from the second floor bedroom, where the fire is believed to have started, according to Woodstock Deputy Fire Chief Terry Menzel.
A husband and wife were displaced to a local motel but were not injured. The fire gutted the upstairs bedroom and there was minimal water damage throughout the home, Menzel said. The fire caused approximately $20,000 in damage and is currently under investigation, he said.
One cat was killed in the blaze, and another was rescued.
No other townhouses were damaged by the fire.
While the fire took place in Woodstock, none of the Woodstock firefighters could respond to the incident as they were attending fellow firefighter Mike Wurtz's funeral Tuesday. Menzel said Woodstock planned ahead to have the other county firefighters cover the town, and he praised the other departments, which covered 16 calls from 8 a.m. to 6:30 p.m., for their support.
"An outpouring of support came from the county fire chiefs," Menzel said. "To step up and send vehicles, and they partook in [Wurtz's funeral] by representing their different departments, nobody ever said no."
"They still covered their calls and gave us the support we needed. It was great."
Crews from Huntley, Hebron, Wonder Lake, Richmond, Cary, Union, McHenry, Nunda rural, Fox River Grove, and Marengo assisted on the call.
Menzel added that there was some difficulty finding a hydrant near the townhouse due to the amount of snow on the ground. He encourages residents to find their hydrants before a fire occurs and shovel at least two feet of snow away so firefighters can find it.
If residents can't find their hydrants or are unable to shovel them, they can call their public works department or the fire department, Menzel said.

Llawhaden Castle is a ruined castle in Llawhaden, Pembrokeshire, Wales, 10 miles (16 km) east of Haverfordwest. A motte-and-bailey castle is thought to have previously occupied the site and the present structure was built by the bishops of the Diocese of St David in the 13th century. The castle was abandoned in the 16th century and some of the stone was removed for local building projects. The site is privately owned by the Lord of the Manor of Llawhaden and managed by Cadw.
The ruins of Llawhaden Castle stands on a hill overlooking the River Cleddau, The remaining ruins date from the early 13th century. It is surrounded by a ditch, which was designed to be only crossable by a drawbridge. The castle is pentagonal in shape and while the north-western and western sides of the castle are no longer present, the other three sides remain. The gatehouse is located on the southern side, which is formed of two drum towers and a gateway. This was also where the drawbridge would have been located to allow entrance to the interior of the castle. The ruins are managed by Cadw, and are open to the public.
Llawhaden and its hinterland were lands owned by the Bishopric of the Diocese of St David, since at least the later years of the realm of Deheubarth. Following the Norman conquest of Deheubarth, these lands (of which Llawhaden and its hinterland were a detached part) became the Marcher Lordship of Dewisland, ruled by the Bishops;[6] it was the only ecclesiastically-ruled Marcher Lordship. Marcher Lords had such great authority that they were almost sovereign.
The first Norman Bishop, Bernard, constructed a castle on the site in the year that he was appointed - 1115. Only a moat and an earth bank from this period survive, although it is thought to have been a motte-and-bailey castle. The stone-built building came later; the vast majority of the ruins seen today date from the construction commissioned by Bishop Adam de Houghton between 1362 and 1389. This was much grander, with two suites of residences situated on the first floor. The gatehouse shown in the picture was probably added at a later date.[8] Additions continued to be made to the castle into the early years of the reign of Henry VIII of England.
The building fell into decline under the control of Bishop William Barlow, the first Bishop appointed after Henry's Laws in Wales Acts had abolished Marcher Lordships. Barlow was an ardent Church Reformist, whose appointment had been encouraged by Thomas Cranmer, and who was significantly unenamoured with St. Davids and its traditions. Barlow sold the lead from the castle roof, supposedly to pay for the dowry of one of his daughters, resulting in damage to the rest of the building from which it never recovered. After the dissolution of the monasteries (which met no resistance from Protestant reformists like Barlow), the castle was completely abandoned, falling into disrepair; it was subsequently quarried for building stone.
In 1930, George Lansbury, then First Commissioner of Works in the Parliament of the United Kingdom, organised a party of 1,300 previously unemployed men for six months to do renovation work on several castles. Llawhaden Castle was among those worked on, with several tasks undertaken including digging out moats and ditches, as well as removing ivy and undergrowth.
Pembrokeshire is a county in the south-west of Wales. It is bordered by Carmarthenshire to the east, Ceredigion to the northeast, and is otherwise surrounded by the sea. Haverfordwest is the largest town and administrative headquarters of Pembrokeshire County Council.
The county is generally sparsely populated and rural, with an area of 200 square miles (520 km2) and a population of 123,400. After Haverfordwest, the largest settlements are Milford Haven (13,907), Pembroke Dock (9,753), and Pembroke (7,552). St Davids (1,841) is a city, the smallest by population in the UK. Welsh is spoken by 17.2 percent of the population, and for historic reasons is more widely spoken in the north of the county than in the south.
Pembrokeshire's coast is its most dramatic geographic feature, created by the complex geology of the area. It is a varied landscape which includes high sea cliffs, wide sandy beaches, the large natural harbour of Milford Haven, and several offshore islands which are home to seabird colonies. Most of it is protected by Pembrokeshire Coast National Park, and can be hiked on the 190-mile (310 km) Pembrokeshire Coast Path. The interior of Pembrokeshire is relatively flat and gently undulating, with the exception of the Preseli Mountains in the north.
There are many prehistoric sites in Pembrokeshire, particularly in the Preseli Mountains. During the Middle Ages several castles were built by the Normans, such as Pembroke and Cilgerran, and St David's Cathedral became an important pilgrimage site. During the Industrial Revolution the county remained relatively rural, with the exception of Milford Haven, which was developed as a port and Royal Navy dockyard. It is now the UK's third-largest port, primarily because of its two liquefied natural gas terminals. The economy of the county is now focused on agriculture, oil and gas, and tourism.
Human habitation of the region that is now Pembrokeshire extends back to between 125,000 and 70,000 years and there are numerous prehistoric sites such as Pentre Ifan, and neolithic remains (12,000 to 6,500 years ago), more of which were revealed in an aerial survey during the 2018 heatwave; in the same year, a 1st-century Celtic chariot burial was discovered, the first such find in Wales. There may have been dairy farming in Neolithic times.
There is little evidence of Roman occupation in what is now Pembrokeshire. Ptolemy's Geography, written c. 150, mentioned some coastal places, two of which have been identified as the River Teifi and what is now St Davids Head, but most Roman writers did not mention the area; there may have been a Roman settlement near St Davids and a road from Bath, but this comes from a 14th-century writer. Any evidence for villas or Roman building materials reported by mediaeval or later writers has not been verified, though some remains near Dale were tentatively identified as Roman in character by topographer Richard Fenton in his Historical Tour of 1810. Fenton stated that he had "...reason to be of opinion that they had not colonized Pembrokeshire till near the decline of their empire in Britain".
Part of a possible Roman road is noted by CADW near Llanddewi Velfrey, and another near Wiston. Wiston is also the location of the first Roman fort discovered in Pembrokeshire, investigated in 2013.
Some artefacts, including coins and weapons, have been found, but it is not clear whether these belonged to Romans or to a Romanised population. Welsh tradition has it that Magnus Maximus founded Haverfordwest, and took a large force of local men on campaign in Gaul in 383 which, together with the reduction of Roman forces in south Wales, left a defensive vacuum which was filled by incomers from Ireland.
Between 350 and 400, an Irish tribe known as the Déisi settled in the region known to the Romans as Demetae. The Déisi merged with the local Welsh, with the regional name underlying Demetae evolving into Dyfed, which existed as an independent petty kingdom from the 5th century. In 904, Hywel Dda married Elen (died 943), daughter of the king of Dyfed Llywarch ap Hyfaidd, and merged Dyfed with his own maternal inheritance of Seisyllwg, forming the new realm of Deheubarth ("southern district"). Between the Roman and Norman periods, the region was subjected to raids from Vikings, who established settlements and trading posts at Haverfordwest, Fishguard, Caldey Island and elsewhere.
Dyfed remained an integral province of Deheubarth, but this was contested by invading Normans and Flemings who arrived between 1067 and 1111. The region became known as Pembroke (sometimes archaic "Penbroke":), after the Norman castle built in the cantref of Penfro. In 1136, Prince Owain Gwynedd at Crug Mawr near Cardigan met and destroyed a 3,000-strong Norman/Flemish army and incorporated Deheubarth into Gwynedd. Norman/Flemish influence never fully recovered in West Wales. In 1138, the county of Pembrokeshire was named as a county palatine. Rhys ap Gruffydd, the son of Owain Gwynedd's daughter Gwenllian, re-established Welsh control over much of the region and threatened to retake all of Pembrokeshire, but died in 1197. After Deheubarth was split by a dynastic feud, Llywelyn the Great almost succeeded in retaking the region of Pembroke between 1216 and his death in 1240. In 1284 the Statute of Rhuddlan was enacted to introduce the English common law system to Wales, heralding 100 years of peace, but had little effect on those areas already established under the Marcher Lords, such as Cemais in the north of the county.
Henry Tudor, born at Pembroke Castle in 1457, landed an army in Pembrokeshire in 1485 and marched to Cardigan. Rallying support, he continued to Leicestershire and defeated the larger army of Richard III at the Battle of Bosworth Field. As Henry VII, he became the first monarch of the House of Tudor, which ruled England until 1603.
The Laws in Wales Act 1535 effectively abolished the powers of the Marcher Lords and divided the county into seven hundreds, roughly corresponding to the seven pre-Norman cantrefi of Dyfed. The hundreds were (clockwise from the northeast): Cilgerran, Cemais, Dewisland, Roose, Castlemartin, Narberth and Dungleddy and each was divided into civil parishes; a 1578 map in the British Library is the earliest known to show parishes and chapelries in Pembrokeshire. The Elizabethan era brought renewed prosperity to the county through an opening up of rural industries, including agriculture, mining and fishing, with exports to England and Ireland, though the formerly staple woollen industry had all but disappeared.
During the First English Civil War (1642–1646) the county gave strong support to the Roundheads (Parliamentarians), in contrast to the rest of Wales, which was staunchly Royalist. In spite of this, an incident in Pembrokeshire triggered the opening shots of the Second English Civil War when local units of the New Model Army mutinied. Oliver Cromwell defeated the uprising at the Siege of Pembroke in July 1648. On 13 August 1649, the Cromwellian conquest of Ireland began when New Model Army forces sailed from Milford Haven.
In 1720, Emmanuel Bowen described Pembrokeshire as having five market towns, 45 parishes and about 4,329 houses, with an area of 420,000 acres (1,700 km2). In 1791 a petition was presented to the House of Commons concerning the poor state of many of the county's roads, pointing out that repairs could not be made compulsory by the law as it stood. The petition was referred to committee. People applying for poor relief were often put to work mending roads. Workhouses were poorly documented. Under the Poor Laws, costs and provisions were kept to a minimum, but the emphasis was often on helping people to be self-employed. While the Poor Laws provided a significant means of support, there were many charitable and benefit societies. After the Battle of Fishguard, the failed French invasion of 1797, 500 French prisoners were held at Golden Hill Farm, Pembroke. From 1820 to 1878 one of the county's prisons, with a capacity of 86, was in the grounds of Haverfordwest Castle. In 1831, the area of the county was calculated to be 345,600 acres (1,399 km2) with a population of 81,424.
It was not until nearly the end of the 19th century that mains water was provided to rural south Pembrokeshire by means of a reservoir at Rosebush and cast iron water pipes throughout the district.
Throughout much of the 20th century (1911 to 1961) the population density in the county remained stable while it rose in England and Wales as a whole. There was considerable military activity in Pembrokeshire and offshore in the 20th century: a naval base at Milford Haven because German U-boats were active off the coast in World War I and, in World War II, military exercises in the Preseli Mountains and a number of military airfields. The wartime increase in air activity saw a number of aircraft accidents and fatalities, often due to unfamiliarity with the terrain. From 1943 to 1944, 5,000 soldiers from the United States Army's 110th Infantry Regiment were based in the county, preparing for D-Day. Military and industrial targets in the county were subjected to bombing during World War II. After the end of the war, German prisoners of war were accommodated in Pembrokeshire, the largest prison being at Haverfordwest, housing 600. The County of Pembroke War Memorial in Haverfordwest carries the names of 1,200 of those that perished in World War I.
In 1972, a second reservoir for south Pembrokeshire, at Llys y Fran, was completed.
Pembrokeshire's tourism portal is Visit Pembrokeshire, run by Pembrokeshire County Council. In 2015 4.3 million tourists visited the county, staying for an average of 5.24 days, spending £585 million; the tourism industry supported 11,834 jobs. Many of Pembrokeshire's beaches have won awards, including Poppit Sands and Newport Sands. In 2018, Pembrokeshire received the most coast awards in Wales, with 56 Blue Flag, Green Coast or Seaside Awards. In the 2019 Wales Coast Awards, 39 Pembrokeshire beaches were recognised, including 11 awarded Blue Flag status.
The Pembrokeshire coastline is a major draw to tourists; in 2011 National Geographic Traveller magazine voted the Pembrokeshire Coast the second best in the world and in 2015 the Pembrokeshire Coast National Park was listed among the top five parks in the world by a travel writer for the Huffington Post. Countryfile Magazine readers voted the Pembrokeshire Coast the top UK holiday destination in 2018, and in 2019 Consumers' Association members placed Tenby and St Davids in the top three best value beach destinations in Britain. With few large urban areas, Pembrokeshire is a "dark sky" destination. The many wrecks off the Pembrokeshire coast attract divers. The decade from 2012 saw significant, increasing numbers of Atlantic bluefin tuna, not seen since the 1960s, and now seen by some as an opportunity to encourage tourist sport fishing.
The county has a number of theme and animal parks (examples are Folly Farm Adventure Park and Zoo, Manor House Wildlife Park, Blue Lagoon Water Park and Oakwood Theme Park), museums and other visitor attractions including Castell Henllys reconstructed Iron Age fort, Tenby Lifeboat Station and Milford Haven's Torch Theatre. There are 21 marked cycle trails around the county.
Pembrokeshire Destination Management Plan for 2020 to 2025 sets out the scope and priorities to grow tourism in Pembrokeshire by increasing its value by 10 per cent in the five years, and to make Pembrokeshire a top five UK destination.
As the national sport of Wales, rugby union is widely played throughout the county at both town and village level. Haverfordwest RFC, founded in 1875, is a feeder club for Llanelli Scarlets. Village team Crymych RFC in 2014 plays in WRU Division One West. There are numerous football clubs in the county, playing in five leagues with Haverfordwest County A.F.C. competing in the Cymru Premier.
Triathlon event Ironman Wales has been held in Pembrokeshire since 2011, contributing £3.7 million to the local economy, and the county committed in 2017 to host the event for a further five years. Ras Beca, a mixed road, fell and cross country race attracting UK-wide competitors, has been held in the Preselis annually since 1977. The record of 32 minutes 5 seconds has stood since 1995. Pembrokeshire Harriers athletics club was formed in 2001 by the amalgamation of Cleddau Athletic Club (established 1970) and Preseli Harriers (1989) and is based in Haverfordwest.
The annual Tour of Pembrokeshire road-cycling event takes place over routes of optional length. The 4th Tour, in April 2015, attracted 1,600 riders including Olympic gold medallist Chris Boardman and there were 1,500 entrants to the 2016 event. Part of Route 47 of the Celtic Trail cycle route is in Pembrokeshire. The Llys y Fran Hillclimb is an annual event run by Swansea Motor Club, and there are several other county motoring events held each year.
Abereiddy's Blue Lagoon was the venue for a round of the Red Bull Cliff Diving World Series in 2012, 2013, and 2016; the Welsh Surfing Federation has held the Welsh National Surfing Championships at Freshwater West for several years, and Llys y Fran Country Park hosted the Welsh Dragonboat Championships from 2014 to 2017.
While not at major league level, cricket is played throughout the county and many villages such as Lamphey, Creselly, Llangwm, Llechryd and Crymych field teams in minor leagues under the umbrella of the Cricket Board of Wales.

The Waibaidu Bridge (Chinese: 外白渡桥; pinyin: Wàibáidù Qiáo), called The Garden Bridge in English, is the first all-steel bridge,[3] and the only surviving example of a camelback truss bridge, in China. The fourth foreign bridge built at its location since 1856, in the downstream of the estuary of the Suzhou Creek, near its confluence with the Huangpu River, adjacent to the Bund in central Shanghai, connecting the Huangpu and Hongkou districts, the present bridge was opened on 20 January 1908. With its rich history and unique design the Waibaidu Bridge is one of the symbols of Shanghai.[4] Its modern and industrial image may be regarded as the city's landmark bridge. On 15 February 1994 the Shanghai Municipal Government declared the bridge an example of Heritage Architecture, and one of the outstanding structures in Shanghai.[5] In an ever-changing metropolis, the Waibaidu Bridge still remains a popular attraction, and one of the few constants in the city skyline.

This structure is about two feet tall and was built in front of the bunker mounds. It wasn't clear who built it or what its purpose is.
This Hyperbolic structure is fairly big, about 30cm, (12 in) and weighs approx. 250gm (9 ounces). I crocheted it using 3 x 8ply balls of yarn at once, with an 8mm hook. It grew quickly, is quite structural, and everyone who sees it, wants to put it on their head!! (It fits like a hat!) A Hyperbolic Hat!

Liesegang banding in quartzite in the Precambrian of Wisconsin, USA.
The Baraboo Ranges of southern Wisconsin are dominated by a hard, erosion-resistant Precambrian metamorphic unit called the Baraboo Quartzite. These rocks were originally marine sandstones and have been subjected to metamorphism and structural folding. Original sedimentary structures are preserved, such as cross-bedding and ripple marks. Baraboo Quartzites vary in color from pinkish to dark reddish to grayish. During metamorphism, quartz overgrowths formed over the original quartz sand grains. Long-term, modern weathering can result in original sand grains being released.
This unit has economic significance - it has been quarried historically and in modern times. The quartzite is broken down into gravel-sized pieces for use as railroad ballast and erosion-control rip-rap.
The lines, or "layers", in the quartzite shown above do not represent sedimentary bedding or lamination or any other sedimentary structures. This thin, closely-spaced banding is called "Liesegang banding". It usually occurs as irregular, reddish or brownish or orangish-brown iron oxide banding in porous rocks, particularly sandstones and pebbly sandstones. These features are almost universally referred to as “Liesegang banding”, representing precipitation lines of iron-rich minerals (e.g., hematite, limonite, goethite, etc.) at & along groundwater chemical interfaces. However, according to Neil Wells of Kent State University, the original concept of Liesegang banding (Liesegang, 1896) does not match up with what is seen in the rock record (see Wells et al., 2003).
True Liesegang banding refers to parallel bands of precipitate formed by diffusion along a single chemical gradient during one event. What's seen in the rock record often consists of sets of irregularly concentric iron bands, with different sets of bands quite frequently oriented in different directions, and showing cross-cutting and dissolution of older sets. Iron oxide banding in the rock record is clearly the result of numerous precipitation events over long periods of time by moving groundwater (Wells et al., 2003). Iron oxide mineralization along these bands appears to be induced by the presence of either a redox interface (change from reducing to oxidizing conditions in the groundwater) or a pH interface (change in acidity).
Because Neil Wells is the first (apparently) to point out that what geologists have been calling Liesegang banding really isn’t, a renaming seems to be in order. It was jokingly suggested in 2003 that the iron banding discussed above be called “Wells Banding”. I’m all for that.
The "Liesegang banding" seen above is unusual in that it is in quartzite, a hard, tight, non-porous metamorphic rock. Before metamorphism, the quartzite was sandstone. The banding was acquired before alteration to quartzite.

This structure was built in 1872 on the Pocahontas town square. It was replaced as the county's capitol in 1940, when the county's current courthouse was constructed to its southwest. It has since housed city offices, the local public library, and other offices.
The two-story Italianate Victorian brick structure features brick quoined corners, a low hipped roof with small central gables on each elevation, and a square cupola with a flared roof. It was placed on the National Register of Historic Places in 1973.
Built in 1854-57 as a Her Majesty’s Prison, this Victorian structure served as a prison, later the Belize City Prison, until 1993. By the 1990, prisoners were then transferred to the Hattieville Prison. In 2002, the facility was restored and was converted to the Museum of Belize.
Belize City is the largest city in Belize. It was once the capital of the former Crown colony of British Honduras (as Belize was known from 1763 to 1964) until the government was moved to the new capital of Belmopan in 1970. As of the 2010 census, Belize City has a population of 61,461 people. The small city is situated at the mouth of Haulover Creek, which is a distributary of the Belize River that empties directly into the Caribbean Sea about five miles north. The city is the country's principal port and its financial and industrial hub. It is even home to a number of the national embassies representing the various countries that have relations with Belize.
The city was almost entirely destroyed in October 1961 when Hurricane Hattie swept ashore. The community has since rebuilt in subsequent decades, but remains vulnerable to sea level rise and hurricanes.

The abandoned and deserted Saladi Beach Hotel in Peloponnese, Greece.
It was a hotel for nudists, closed under pressure of the church. The structure is deteriorating and crumbling into ruins. Now this place sits in decay.
Saladi Beach (sometimes spelled Salanti Beach) is located in a beautiful wide valley. There is a large and very clean pebble beach. But especially exciting is this huge abandoned complex.
Although the 8-story building complex blights the otherwise beautiful valley, the sprawling area, abandoned to decay since the mid-1980s, also offers many opportunities for exciting discovery tours up to the roof, from where you have a spectacular view of the surrounding area.
