Devils Tower (also known as Bear Lodge Butte) is a butte, possibly laccolithic, composed of igneous rock in the Bear Lodge Ranger District of the Black Hills, near Hulett and Sundance in Crook County, northeastern Wyoming, above the Belle Fourche River. It rises 1,267 feet (386 m) above the Belle Fourche River, standing 867 feet (265 m) from summit to base.

The Ladder at Devils Tower was first constructed and used in 1893 by William Rogers and Willard Ripley to publicly ascend Devil's Tower. Two years later Roger's wife Linnie ascended the tower via the ladder, one of a total of about 215 who have used the ladder. The last use was by Babe "The Human Fly" White in 1927.
