Roosevelt Arch, Yellowstone National Park

The Roosevelt Arch, the formal North Entrance to Yellowstone National Park at Gardiner, Montana, has a rich history within a park that is steeped in historical associations. Its creation is intertwined with the Northern Pacific Railway (NPR) and the story of regional transportation; with the work of renowned army engineer Hiram Chittenden and the long involvement of the U.S. Army Corps of Engineers in Yellowstone; with the conservation achievements and irrepressible personality of Theodore Roosevelt; with the honored traditions of the Masons of Montana; and with the communities, colorful characters, and business interests of Gardiner and Mammoth Hot Springs.
