History
Nearby Dull Knife Battlefield is the site of an 1876 battle between the U.S. Army and Cheyenne.

From the late 1860s to about 1910, the Hole-in-the-Wall mountain pass was used by outlaws such as Butch Cassidy. Several gangs kept a cabin nearby.

Mayoworth is named after Mae Marie Jones and William Worthington Morgareidge. It’s a combination of their two names.
