<P> The buffalo head gives this story special significance for the Northern Cheyenne . All the Cheyenne maintained in their camps a sacred teepee to the Great Medicine containing the tribal sacred objects . In the case of the Northern Cheyenne, the sacred object was a buffalo head . </P> <P> Fur trappers may have visited Devils Tower, but they left no written evidence of having done so . The first documented Caucasian visitors were several members of Captain William F. Raynolds' 1859 expedition to Yellowstone . Sixteen years later, Colonel Richard I. Dodge escorted an Office of Indian Affairs scientific survey party to the massive rock formation and coined the name Devils Tower . Recognizing its unique characteristics, the United States Congress designated the area a U.S. forest reserve in 1892 and in 1906 Devils Tower became the nation's first National Monument . </P> <P> The 1977 movie Close Encounters of the Third Kind used the formation as a plot element and as the location of its climactic scenes . Its release was the cause of a large increase in visitors and climbers to the monument . </P> <P> In recent years, climbing Devils Tower has increased in popularity . The first known ascent of Devils Tower by any method occurred on July 4, 1893, and is accredited to William Rogers and Willard Ripley, local ranchers in the area . They completed this first ascent after constructing a ladder of wooden pegs driven into cracks in the rock face . A few of these wooden pegs are still intact and are visible on the tower when hiking along the 1.3 - mile (2.1 km) Tower Trail at Devils Tower National Monument . Over the following thirty years many climbs were made using this method before the ladder fell into disrepair . The man most famous for climbing the tower is Fritz Wiessner, who summited with William P. House and Lawrence Coveney in 1937 . This was the first ascent using modern climbing techniques . Wiessner led the entire climb free, placing only a single piece of fixed gear, a piton, which he later regretted, deeming it unnecessary . </P>
