Mount Isto

Mount Isto is the highest peak in Alaska’s Brooks Range, located in the eastern range’s Romanzof Mountains within the Arctic National Wildlife Refuge. Rising in a remote expanse of rugged, protected wilderness, it stands about 5 miles south of Mount Hubley, the Brooks Range’s second-highest summit. The mountain was named in 1966 for Reynold E. “Pete” Isto, a civil engineer with the U.S. Geological Survey. For many years Mount Chamberlin was believed to be the tallest peak in the Brooks Range, but improved measurement technology in 2014 confirmed Mount Isto as the highest summit and moved Mount Chamberlin to third place.
