Prehistoric proglacial lake
Glacial Lake Albany was a prehistoric North Americanproglacial lake that formed during the end of theWisconsinan glaciation .[ 2] [ 3] It existed between 15,000 and 12,600 years ago and was created whenmeltwater from a retreating glacier, along with water from rivers such as theIromohawk , becameice dammed in theHudson Valley .[ 2] [ 4] [ 5]
Organic materials in Lake Albany deposits have beencarbon dated to approximately 11,700 years ago.[ 6] The lake spanned approximately 160 miles (260 km) from present-dayPoughkeepsie toGlens Falls .[ 2] [ 4] [ 7]
Lake Albany drained about 10,500 years ago through theHudson River due topost-glacial rebound .[ 2] [ 7] [ 8] When the lake drained it exposed the sandy and gravellyglaciolacustrine deposits left by the glacier, along a broad plain just west ofSchenectady , where the Mohawk emptied into the lake.[ 9] Dune anddeltaic sands, containinglenses of silty sand, silt and clay,[ 10] compose thetopsoil which now underlies theAlbany Pine Bush .[ 11] Beneath the surficial deposits are lake-bottom silt and clay, which overlietill and shale bedrock.[ 10] A smallrill caused by the lake's drainage createdPatroon Creek , Sand Creek,Lisha Kill , Shaker Creek, Delphus Kill and the Salt Kill in the town ofColonie, New York .[ 12]
