In December 1961, Knievel, learning about the culling of elk in Yellowstone Park, decided to hitchhike from Butte to Washington, D.C., to raise awareness and to have the elk relocated to areas open to hunters. He presented his case to Representative Arnold Olsen, Senator Mike Mansfield and Kennedy administration Interior Secretary Stewart Udall. As a result of his efforts, the slaughter was stopped, and the animals have since been regularly captured and relocated to areas of Montana, Wyoming and Idaho.
