The Mammoth Hot Springs Historic District includes Fort Yellowstone, where 35 structures remain from the 1890s and early 1900s when the US Army administered the park. Significant conservation policies were developed here that led to the origin of the National Park Service. The Mammoth Hot Springs Historic District has statewide significance as the administrative and concession headquarters of the largest national park in Wyoming. Fort Yellowstone is also listed as a National Historic Landmark District, the highest designation.
The nationally significant Fort Yellowstone-Mammoth Hot Springs Historic District is in the northwestern portion of Yellowstone National Park on an old hot springs formation. The buildings on this plateau represent the first development of administrative and concession facilities in the park.
For the decade after 1872 when Yellowstone National Park was established, the park was under serious threat from those who would exploit, rather than protect, its resources. Poachers killed animals. Souvenir hunters broke large pieces off the geysers and hot springs. Developers set up camps for tourists, along with bath and laundry facilities at hot springs. Civilian superintendents were hired to preserve and protect this land from 1872 through 1886. The good intentions of these early administrators, however, were no match for their lack of experience, funds and manpower. Word got back to Congress that the park was in trouble and legislators refused to appropriate any funds for the park's administration in 1886.
