Langford, another superintendent was a member of the Washburn Expedition and advocate of the Yellowstone National Park Act, was made a volunteer who greatly helped the park.</span><span> He entered the park at least twice during five years in office—was in the 1872 Hayden Expedition and to evict a squatter in 1874.
