Devils Tower and Surrounding Layers

But using the Indian name wouldn’t help since American Indian tribes referred to it by many names too, including Tso-i-e, or “standing on a rock” by the Kiowa, “Bear's Tipi” by the Arapaho, Mato Tipila or “Bear Lodge” by the Lakota, Na Kovehe or “Bear's Lodge” by the Cheyenne, and “Bear's House” by the Eastern Shoshone. In the 19th century, Colonel Richard Dodge led an expedition into the Black Hills. He modified an interpretation of the unattributed Indian name “The Bad God's Tower” into “Devils Tower.” Regardless it was the first national monument under the authority of the Antiquities Act of 1906.
