The three sacred sites, Devils Tower, situated in the Lakota Black Hills; the Four Corners of the Hopi in Arizona; and the Winnemem Wintu's Mount Shasta, are places of extraordinary beauty. They have been sites of controversy over differing ideas of how to use the land among American Indians and non-Indians. The Lakota, Hopi, and Winnemem Wintu consider the land sacred. Users such as mining companies, New Age practitioners, and rock climbers think of the land as a material resource best used for industry and recreation.
