The True Story of Dead Horse Point
In the l800s wild mustang herds were common in this area. This peninsula, 2000 feet above the Colorado River, was used to corral and capture them behind a 50 ft. fence at the neck of the formation. One time a herd of unwanted horses was left out there, where they died of thirst.
