The Sublett Mountains extend from the Snake River Plain south almost to Snowville on the Idaho/Utah border. From the surrounding valleys, the range resembles a low grouping of rugged hills. However, this range which is a meeting ground between the Great Basin and the Snake River Plain is much more complicated and diverse than it appears from the valleys.
The highest point in the range, Peak 7492 (Roy Peak), is officially unnamed and reaches 7,492 feet; 7,464-foot Cedar Creek Peak is the highest named summit. In addition to these two peaks there are five other peaks that reach above 7,000 feet including Heglar Benchmark at 7,400 feet, Hartley Mountain at 7,456 and Quaking Aspen Mountain at 7,230 feet. The Subletts are yet another product of Basin and Range faulting. Most of the range’s rock is sedimentary but in places younger volcanic rocks are found on the surface.
The Sublett Mountains, one peak and two access points are briefly discussed on page 353 of the book. Private property complicates or closes of access to some parts of the range. Rick Baugher has logged more Sublett Mountains summits than any other climber.
