Tower Ladder (Devils Tower National Monument)

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.
