Coös County, New Hampshire

Geography and landscape

Coös County covers a large, largely forested area that includes portions of the White Mountains and extensive river valleys. The county borders the Canadian province of Quebec to the north and contains a mix of mountainous terrain, lakes, and working forests. Much of the land is rural, with small towns, unorganized townships and large tracts of public forest.

History and name

Established in 1803, Coös County was created during the early period of New Hampshire’s county organization. The name is often styled with a diaeresis (Coös) to indicate two syllables; historical spellings also appear without it. The region developed through logging, small-scale farming, and later light industry tied to timber and paper production.

Economy, communities and demographics

The county’s economy has long been centered on natural-resource industries, seasonal tourism, and services for small communities. Larger settlements such as Berlin and Gorham serve as local commercial nodes, while Lancaster functions as the administrative center. Population trends over recent decades have been flat to declining, typical of rural northern New England counties following industrial changes and outmigration.

Recreation and conservation

Outdoor recreation is a major feature: hiking, snowmobiling, hunting, fishing and winter sports draw visitors to the White Mountain foothills and public forests. Portions of national and state forest land provide protected habitat and trails. Conservation efforts balance recreation, timber harvest and watershed protection.
