Yellowstone Heritage and Research Center
Yellowstone National Park’s archives, library, and museum collections contain more than 5.3 million items, making them the second largest in the National Park Service. Most of these items are kept in the Heritage and Research Center (HRC), which is located outside the park entrance in Gardiner, Montana. The HRC is a storage facility that also houses the park’s herbarium and archeology lab, and features small rotating exhibits in the lobby. The library is open to the public Tuesdays through Fridays, and the archives and museum collections may be accessed for research purposes by appointment.
