Support Your Park

You can help support Jefferson National Expansion Memorial!

With every tram ride to the top of the Gateway Arch and every book bought in any of the park's museum stores, you can help to support the programs and resources at Jefferson National Expansion Memorial (JNEM). The proceeds from your purchase of tickets and educational gifts goes toward helping maintain and improve the museums, property and grounds, as well as present educational programs, acquire historical artifacts and publish literature. These activities are made possible by JNEM's cooperating association, Jefferson National Parks Association, and park partner, Metro.

Jefferson National Parks Association (JNPA) is a federally recognized National Park Service cooperating association. As a private non-profit organization, JNPA supports the educational activities of JNEM, as well as other public lands such as Ulysses S. Grant National Historic Site in St. Louis, National Great Rivers Museum in Alton, IL, Lewis and Clark Visitor Center in Yankton, SD, Central High School National Historic Site in Little Rock, AR, Mississippi National River and Recreation Area in St. Paul, MN, Voyageurs National Park in International Falls, MN and Chippewa National Forest in Cass Lake, MN.

JNPA's major source of funding is through the sale of educational products, in museum stores, online sales, and private donations. As a tax-exempt, non-profit organization identified under section 501(c)(3) of the federal tax code, all JNPA proceeds fund its educational mission and all donations are tax-deductible as allowed by law.
