 In 1989, UNESCO designated the area around Lake Champlain as the Champlain-Adirondack Biosphere Reserve.The Alburgh Peninsula (also known as the Alburgh Tongue), extending south from the Quebec shore of the lake into Vermont, and Province Point, the southernmost tip of a small promontory approximately in size a few miles (kilometres) to the northeast of the town of East Alburgh, Vermont, are connected by land to the rest of the state only via Canada.This is a distinction shared with the state of Alaska, Point Roberts, Washington, and the Northwest Angle in Minnesota.
