HISTORY
The magnetism of names like “Sundance”
and “Devils Tower” draw the traveler to this
spacious park. The area was reserved by
treaty for the Sioux tribes until the great Black
Hills gold rush in 1874. Conflicts with Native
Americans grew during this time, and the
Sioux lost control of the region. Keyhole State
Park was named for the “Keyhole” livestock
brand that was used by two brothers by the
name of McKean. They had established a
ranch in the area. Keyhole Dam, an earthfill
structure, was completed by the Bureau of
Reclamation in 1952.
