Champlain Valley - Geology and Physiography

Geology and Physiography

The Champlain Valley is among the northernmost valleys considered part of the Great Appalachian Valley reaching from Canada to Alabama.

The Champlain Valley is a physiographic section of the larger Saint Lawrence Valley province, which in turn is part of the larger Appalachian physiographic division.

Lake Champlain is situated in the Champlain Valley between the Green Mountains of Vermont and the Adirondack Mountains of New York, drained northward by the Richelieu River into the St. Lawrence River at Sorel-Tracy, Quebec (northeast of Montreal) and fed by Otter Creek, the Winooski, Missisquoi, and Lamoille Rivers in Vermont, and the Ausable, Chazy, Boquet, and Saranac Rivers in New York. Lake Champlain also receives water from Lake George via the La Chute River.
