Northern Prairie Wildlife Research Center
Captain William Jones headed a military expedition to Yellowstone Park in 1873. The purpose of the expedition was to locate a military road from the Union Pacific Railroad in southern Wyoming to the Park. Included on his staff were naturalists and geologists which resulted in reports on insects (J.D. Putnam), plants (C.C. Parry) and geology (T. Comstock). It was during this expedition that Togwoheap Pass was discovered which opened up the southern portion of Yellowstone for future exploration.
