"Why is it called Devils Tower? Some Native Americans called it Mato Tipila, meaning Bear Lodge. Other Native American names include Bear's Tipi, Home of the Bear, Tree Rock and Great Gray Horn. In 1875, on an expedition led by Col. Dodge, it is believed his interpreter misinterpreted the name to mean Bad God's Tower, later shortened to Devils Tower."

"Since its inception in 1890, the U.S. Board on Geographic Names has discouraged the use of the possessive form—the genitive apostrophe and the 's'. The possessive form using an 's' is allowed, but the apostrophe is almost always removed. The Board's archives contain no indication of the reason for this policy."
