After word spread about the magnificent big game in Yellowstone Park, hunters from the eastern United States and Europe began coming to bag a trophy. Even if they were skilled hunters where they came from, they needed someone to guide them in the rugged West. Jack Bean had the perfect credentials for the job. Before hiring out as a guide, Bean had been a trapper, hunter and Indian fighter.
In the summer of 1877, the U.S. Army hired Bean to look for Chief Joseph and his band of Nez Perce Indians along the Madison River and in Yellowstone Park. He returned to Bozeman after locating the Indians and telling the Army they were headed into Yellowstone Park. Bean discovered that a Colonel Pickett wanted to hire him as a hunting guide. In his memoir, Bean tells this tale about the intrepid colonel.
