Glacial Lake Albany was a prehistoric North American proglacial lake that formed during the end of the Wisconsinan glaciation. It existed between 15,000 and 12,600 years ago and was created when meltwater from a retreating glacier, along with water from rivers such as the Iromohawk, became ice dammed in the Hudson Valley. Organic materials in Lake Albany deposits have been carbon dated to approximately 11,700 years ago.The lake spanned approximately 160 miles (260 km) from present-day Poughkeepsie to Glens Falls. Lake Albany drained about 10,500 years ago through the Hudson River due to post-glacial rebound. When the lake drained it exposed the sandy and gravelly glaciolacustrine deposits left by the glacier, along a broad plain just west of Schenectady, where the Mohawk emptied into the lake. Dune and deltaic sands, containing lenses of silty sand, silt and clay, compose the topsoil which now underlies the Albany Pine Bush. Beneath the surficial deposits are lake-bottom silt and clay, which overlie till and shale bedrock. A small rill caused by the lake's drainage created Patroon Creek, Sand Creek, Lisha Kill, Shaker Creek, Delphus Kill and the Salt Kill in the town of Colonie, New York.

Albany Pine Bush
Albany Pine Bush

The Albany Pine Bush, referred to locally as the Pine Bush, is one of the largest of the 20 inland pine barrens in the world. It is centrally located in New York's Capital District within Albany and Schenectady counties, between the cities of Albany and Schenectady. The Albany Pine Bush was formed thousands of years ago, following the drainage of Glacial Lake Albany.The Albany Pine Bush is the sole remaining undeveloped portion of a pine barrens that once covered over 40 square miles (100 km2), and is "one of the best remaining examples of an inland pine barrens ecosystem in the world." By 2008 it included all parcels of the Albany Pine Bush Preserve (a state nature preserve spanning 3,200 acres (1,300 ha)), the properties that connect these protected parcels, and some of the surrounding areas that abut the preserve. The 135-acre (55 ha) Woodlawn Preserve and surrounding areas in Schenectady County are the western sections of the Pine Bush, separated geographically by other properties from the Albany Pine Bush Preserve in Albany County.Historically regarded as desolate and dangerous to cross, the Pine Bush has come to be seen as a historical, cultural, and environmental asset to the Capital District and Hudson Valley regions of New York. It is home to the Karner blue butterfly, an endangered species first identified by author Vladimir Nabokov in 1944 using a type specimen from the Pine Bush. In 2014, Albany Pine Bush was designated as a National Natural Landmark by the National Park Service.
