The US Army administered the park from 1886 through 1918.

In 1910, at the height of the Army's presence in Yellowstone, there were 324 soldiers here, plus some families and numerous civilian employees. These troops staffed Fort Yellowstone and the park's outposts, including the Norris Soldier Station.

From the outposts, the cavalry patrolled the park by horse in the summer and on skis during the winter, stopping at patrol cabins along the way.

Fort Yellowstone Self-Guiding Trail

Located in Mammoth Hot Springs and included in this app.

The exhibits describe life in Fort Yellowstone when the US Army administered the park from 1886 through 1918. Significant conservation policies were developed here that lead to the origin of the National Park Service.
