county, northern New Hampshire, U.S. It consists of a mountainous region bounded by Quebec, Canada, to the north, Maine to the east, the White Mountains to the south, and Vermont to the west. The Connecticut River, rising in the Connecticut lakes in northern Coos county, flows down the length of the Vermont border. Other waterways include the Androscoggin, Upper Ammonoosuc, Magalloway, and Swift Diamond rivers, as well as Umbagog Lake. The county encompasses portions of the White Mountain National Forest, which contains the series of summits known as the Presidential Range-including Mount Washington (6,288 feet [1,917 metres]), the highest peak in New England. The Appalachian National Scenic Trail crosses the southern part of the county. Among the many state parks are Coleman, Lake Francis, Moose Brook, Weeks, Forest Lake, Milan Hill, and Dixville Notch. Forested areas-largely spruce, white pine, and balsam fir-include Nash Stream, Connecticut Lakes, and Cape Horn state forests. Several covered truss bridges remain in the western part of the county.
