Lake Champlain (; French: ''Lac Champlain'') is a natural freshwater lake in North America, located mainly within the borders of the United States (states of Vermont and New York) but partially situated across the Canada–United States border in the Canadian province of Quebec. The New York portion of the Champlain Valley includes the eastern portions of Clinton County and Essex County. Most of this area is part of the Adirondack Park. There are recreational opportunities in the park and along the relatively undeveloped coastline of Lake Champlain. The cities of Plattsburgh, New York and Burlington, Vermont are on the west and east shores of the lake, respectively, and the village of Ticonderoga, New York is located in the southern part of the region. The Quebec portion is located in the regional county municipalities of Le Haut-Richelieu and Brome-Missisquoi. There are a number of islands in the lake; the largest include the towns of South Hero, Grand Isle, North Hero, Alburgh, and Isle La Motte, all belonging to Grand Isle County in the state of Vermont. ==Geology== The Champlain Valley is the northernmost unit of a landform system known as the Great Appalachian Valley, which stretches from Quebec to Alabama. The Champlain Valley is a physiographic section of the larger Saint Lawrence Valley, which in turn is part of the larger Appalachian physiographic division.〔(【引用サイトリンク】publisher=U.S. Geological Survey )〕 It is one of numerous large lakes located in an arc from Labrador through the northern United States and into the Northwest Territories of Canada. Although it is smaller than each of the Great Lakes: Ontario, Erie, Huron, Superior, or Michigan, Lake Champlain is a large body of fresh water. Approximately in area, the lake is roughly long, and across at its widest point.〔 (【引用サイトリンク】date=February 12, 2011 ) 〕 The maximum depth is approximately .
