Prehistoric proglacial lake
Glacial Lake Albany was a prehistoric North American
proglacial lake that formed during the end of the
Wisconsinan glaciation.
[1]
[2] It existed between 15,000 and 12,600 years ago
[3] 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.
[1]
[4] Organic materials in Lake Albany deposits have been
carbon dated to approximately 11,700 years ago.
[5] The lake spanned approximately 160 miles (260 km) from present-day
Poughkeepsie to
Glens Falls.
[1]

[6]
Lake Albany drained about 10,500 years ago through the
Hudson River due to
post-glacial rebound.
[1]
[6]
[7] 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.
[8]
Dune and
deltaic sands, containing
lenses of silty sand, silt and clay,
[9] compose the
topsoil which now underlies the
Albany Pine Bush.
[10] Beneath the surficial deposits are lake-bottom silt and clay, which overlie
till and shale bedrock.
[9] 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.
