Yellowstone National Park history

Everts was an I.R.S. Agent from Montana invited to participate in the first official expedition to Yellowstone in 1870. His 37-day journey through the wilderness was marred by a series of unfortunate events.

March 1, 1872, President Ulysses S. Grant signed a bill, officially establishing Yellowstone National Park. 146 years later, it remains a symbol of national pride.
