Lassen Volcanic National Park, established on August 9, 1916, and containing more than 160 square miles, is administered by the National Park Service, U. S. Department of the Interior.

The National Park System, of which this park is a unit, is dedicated to conserving the scenic, scientific, and historic heritage of the United States for the benefit and enjoyment of its people.

Created in 1849, the Department of the Interior—America’s Department of Natural Resources—is concerned with the management, conservation, and development of the Nation’s water, wildlife, mineral, forest, and park and recreation resources. It also has major responsibilities for Indian and Territorial affairs.

As the Nation’s principal conservation agency, the Department works to assure that nonrenewable resources are developed and used wisely, that park and recreational resources are conserved for the future, and that renewable resources make their full contribution to the progress, prosperity, and security of the United States—now and in the future.
