Grand Canyon Association

Grand Canyon Association was founded in 1932 as the Grand Canyon Natural History Association by naturalist Edwin “Eddie” McKee. A ranger working on the South Rim of Grand Canyon National Park, McKee saw the need for a park partner that would support interpretive programs and publications about the canyon, and from its beginnings the natural history association did just that, funding interpretive talks, research and scientific papers.

Today, Grand Canyon Association still serves its founding mission—and much more. Membership, general-audience publications, educational outreach, a field institute and philanthropy programs were added over the years to serve the association's mission of cultivating support, education and understanding of Grand Canyon.

Each year GCA provides millions of dollars and countless service hours to Grand Canyon National Park to protect, inspire and teach. By supporting the association, you join a decades-old community that shares in the wonder of this national treasure and preserves it for future generations. Thank you!
