The National Park Foundation
"The National Park Foundation, the official charitable partner of the National Park Service, enriches America’s national parks and programs through the support of private citizens, park lovers, stewards of nature, history enthusiasts, and wilderness adventurers. Chartered by Congress in 1967, the Foundation grew out of a legacy of park protection that began over a century ago, when ordinary citizens took action to establish and protect our national parks."
