Museum Collection

One of more than 150 skulls and skeletal materials in the museum collection from the park’s Wolf Project, wolf 007F was released in Yellowstone in 1995 as a Rose Creek pup. She joined 002M from the Crystal Creek pack in 1996 to form the Leopold Pack, the first naturally formed pack of the new era. She was killed by wolves of the Geode Creek pack in 2002.



Yellowstone’s museum collection contains more than 720,000 items that, along with the archives and library collection, document the cultural and natural history of the park. The museum collection consists of natural history, archeological, and cultural objects, including obsidian points, skulls from the first wolves reintroduced in the park, Thomas Moran’s original watercolor field sketches, William Henry Jackson’s photographs, furniture from the historic hotels and other historic structures, and an extensive historic vehicle collection ranging from stagecoaches and wagons, through early buses and automobiles, to fire trucks and a snowmobile.

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 hundreds of images from Yellowstone’s collections.

While the Heritage and Research Center does have some rotating exhibits in the lobby area, the facility was not designed to be a museum, but rather a research center and a state-of-the-art storage facility. With exception of some restricted collections, such as Thomas Moran’s original watercolor field sketches, William Henry Jackson’s photographs, and other rare or fragile items, the museum collections are accessible to researchers by appointment only and require at least 24-hours advanced notice.



The museum collection is open by prior appointment. Appointments are generally available Monday-Thursday, 9am-4pm, with at least 48 hours notice. Email us for more information.
