Like the more famous Cedar Breaks National Monument, Ashdown Gorge is known for its multicolored rock formations and plateau-top stands of 1,000-year-old bristlecone pines. The Gorge is named after the family of George Ashdown who set up a sawmill there in 1898. Today there are 320 acres (1.3 km2) of private land inholdings mostly surrounded by the wilderness.
In 2006, Iron County officials were considering a proposal to expand Cedar Breaks National Monument to include the Ashdown Gorge Wilderness, the private inholdings and nearby Flanigan Arch. With congressional approval the area would be renamed Cedar Breaks National Park.
