National Natural Landmark

The National Natural Landmark (NNL) program recognizes and encourages the conservation of outstanding examples of the United States' natural history. The program was established on May 18, 1962 by United States Secretary of the Interior Stewart Udall relying on authority provided by the Historic Sites Act of 1935. It is the only natural areas program of national scope that identifies and recognizes the best examples of biological and geological features in both public and private ownership.

The registry includes nationally significant geological and ecological features in 48 states, American Samoa, Guam, Puerto Rico and the Virgin Islands.

The National Park Service administers the NNL Program, and if requested, assists NNL owners and managers with the conservation of these important sites. Land acquisition by the federal government is not a goal of this program; NNLs are nationally significant sites owned by a variety of land stewards, and participation in the program is voluntary.
