Context paragraphs:
Glen Lake: Glen Lake is a lake located in Leelanau County in the U.S. state of Michigan, near Lake Michigan.  Several villages and hamlets lie along or near its shore, including Burdickville, Glen Arbor, and Glen Haven.  The lake actually consists of two large bodies of water connected by a narrow channel crossed by the State Route 22 bridge, with the larger body to the east being referred to as "Big Glen Lake" and the smaller body to the west as "Little Glen Lake".  The two bodies, collectively referred to as Glen Lake, are at the same level and hydrologically similar.  The total surface area of the two bodies are 4871 acre and 1415 acre , with maximum depths of 130 ft and 13 ft respectively.  Big Glen Lake is nearly perfectly round, while Little Glen is more elongated.  The lakes empty into Lake Michigan via the shallow Crystal River which winds through Glen Arbor.

Florissant Fossil Beds National Monument: The Florissant Fossil Beds National Monument is a national monument located in Teller County, Colorado.  The location is famous for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales of the Florissant Formation.  Based on argon radiometric dating, the formation is Eocene (approximately 34 million years old ) in age and has been interpreted as a lake environment.  The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing an diatom bloom.  As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls.  Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils.

Beecher's Trilobite Bed: Beecher's Trilobite Bed is a Konservat-Lagerstätte of Late Ordovician (Caradoc) age located within the Frankfort Shale in Cleveland's Glen, Oneida County, New York, USA.  Only 3-4 centimeters thick, Beecher's Trilobite Bed has yielded numerous exceptionally preserved trilobites with the ventral anatomy and soft tissue intact, the soft tissue preserved by pyrite replacement.  Pyritisation allows the use of X-rays to study fine detail of preserved soft body parts still within the host rock.  Pyrite replacement of soft tissue is unusual in the fossil

Margaret Lake (Glacier County, Montana): Margaret Lake is located in Glacier National Park, in the U. S. state of Montana.  Margaret Lake is less than .50 mi north of Ipasha Lake.  Margaret Lake is fed by Pyramid Creek as well as melt waters from Chaney Glacier.

Ernest Greenfield: Ernest Greenfield was a British archaeologist.  He served with the Royal Air Force during the Second World War.  During war service he became friends with Philip Rahtz who persuaded Greenfield to take up professional archaeology.  His excavations included the Great Witcombe Roman Villa, Gloucestershire (1960–1973), and Chew Valley Lake, north Somerset (1953).  Greenfield grew up in Sidcup, Kent and was a schoolboy when he set out to single-handedly excavate a Roman site at Horwood's Pit, St. Pauls Cray, whilst gravel extraction operations were being carried out in the 1930s.  He was not popular with the gravel company, and subsequently contacted A.H.A. Hogg for help in the investigations.  Hogg later drew up a plan of the site, and sought further help for Greenfield from Norman Cook at Maidstone Museum.  In a letter to Cook, preserved at the museum, Hogg stated that Greenfield 'had the right ideas, but was discouraged 'after having lost his finds and site notes off the back of his motorbike!'  Later Greenfield set up a local archaeological group which discovered many new sites including the famous Lullingstone Villa.

Margaret Hogg: Margaret Hogg (c. 1939 – October 1976) was a manslaughter victim whose body was preserved in Wast Water, Lake District National Park, Cumbria, for eight years.  Married to Peter Hogg, she had worked as an airline stewardess for Air Europe; her husband was a pilot.

Lake Margaret Power Station: The Lake Margaret Power Stations comprise two hydroelectric power stations located in Western Tasmania, Australia.  The power stations are part of the KingYolande Power Scheme and are owned and operated by Hydro Tasmania.  Officially the Upper Lake Margaret Power Station, a conventional hydroelectric power station, and the Lower Lake Margaret Power Station, a mini-hydroelectric power station, the stations are generally collectively referred to in the singular format as the Lake Margaret Power Station.  The stations are located approximately 2.5 km apart.

Wast Water: Wast Water or Wastwater ( ) is a lake located in Wasdale, a valley in the western part of the Lake District National Park, England.  The lake is almost 3 mi long and more than 1/3 mile wide.  It is the deepest lake in England at 258 ft , and is owned by the National Trust.  It is one of the finest examples of a glacially 'over-deepened' valley.  The surface of the lake is about 200 feet above sea level, while its bottom is over 50 feet below sea level.

Black Lake (Louisiana): Black Lake is a reservoir located between Creston and Campti in North Louisiana.  Water feeds into Black Lake from Black Lake Bayou, a watershed that extends from north of Gibsland in Bienville Parish and south to Clarence in Natchitoches Parish through the parishes of Claiborne, Webster, Bienville, Red River and Natchitoches.  The elevation of the lake is 102 ft .  Louisiana Highway 9 runs across Black Lake.  On the west side of Highway 9 the body of water is called Black Lake — the east is called Clear Lake or Clear Lake Bayou.  The Clear Lake side is near another body of water: Saline Lake.  Between Clear Lake and Saline Lake is the Alan Chiverly Dam, constructed in 1934.  Road 1226 also extends between the lakes.

Lake Ezerische: Lake Ezerische (Belarusian: Возера Езярышча , Russian: Oзеро Езерище ) is lake in Haradok district, Vitebsk Voblast of Belarus and is situated at the border with the Pskov Oblast of the Russia.  In 1959, on the river flowing out of Lake an hydroelectric power plant was built.  This led to the raising of the water level (as the lake began to function as a reservoir).  Raising the water level leads to erosion of its banks.  The lake is dated to the Glacial period and is about 10,000 years.  The largest settlement on the bank of the lake is Ezerische a settlement located on the western shore of the lake.  On one of the islands in Lake located Ezerishche Castle.  Up to the present day only ramparts of the castle preserved.
