Yellowstone’s museum collection contains more than 300,000 items that, along with the archives and library collection, document the cultural and natural history of the park. The museum collection includes archeological artifacts and fossils; uniforms, weapons and vehicles; hotel furnishings, souvenirs, and ephemera; rocks and minerals; wildlife and herbarium specimens; illustrated manuscripts; Thomas Moran watercolors and other original works of art; and over 90,000 photographs and stereographs, including more than 1,000 images by photographer William Henry Jackson. The collection is used each year by park staff and other researchers looking for background information on Yellowstone history, specific reference material, and illustrations for commercial products, school programs, special events and adult education. The televised series, “The National Parks: America’s Best Idea,” by Ken Burns contained almost 1,000 images from Yellowstone’s collections.
