The White Mountain National Forest (WMNF) is a federally-managed forest contained within the White Mountains in the northeastern United States. It was established in 1918 as a result of the Weeks Act of 1911; federal acquisition of land had already begun in 1914. It has a total area of 784,505 acres (3,175 km2) (1,225 sq mi). Most of the WMNF is in New Hampshire; a small part (about 5.65% of the forest) is in the neighboring state of Maine. While often casually referred to as a park, this is a National Forest, used not only for hiking, camping, and skiing, but for logging and other limited commercial purposes.
