NPCA's Timeline: 1961-1980

June 26, 1961:	NPA petitions to intervene in the Marble Canyon lawsuit, seeking to protect the Grand Canyon from two proposed dams. NPA wins the battle to protect the canyon four years later.
1962:	NPA leads the fight against revising hunting policies in the congressionally designated parks.
1978:	The Redwood National Park Expansion Act of 1978 is passed by Congress, after NPCA's first State of the Parks report in 1963 raised concerns about National Park Service's management of natural resources.
1980:	NPCA awards its first William Penn Mott Park Leadership Award to Representative Morris Udall. The annual award recognizes the outstanding efforts of a member of Congress or other public official who stands as a strong advocate of the National Park System. NPCA launched a multi-year effort to update existing research on visitor impacts and creates the Visitor Impact Management System (VIMS), for setting visitor standards and limits in the parks. VIMS served as a model for National Park Service's Visitor Experience and Resource Protection planning.
