Mount Isto, Mountain summit in Brooks Range, Alaska, US
Mount Isto rises to 8,976 feet in elevation, making it the highest peak in the Brooks Range and the tallest point in the US-Canadian Arctic region.
The mountain received its name in 1966 to honor Reynold E. Isto, a civil engineer who contributed to Alaskan mapping through helicopter-based survey methods.
Scientists and mountaineers regularly study this peak to understand Arctic climate patterns and geological formations within the Arctic National Wildlife Refuge boundaries.
Reaching Mount Isto requires arranging bush plane transportation to land on tundra valleys, followed by navigating steep ridges and small glaciers to the summit.
Advanced measurement technology in 2014 confirmed Mount Isto's status as the highest peak in the Brooks Range, surpassing previous measurements of Mount Chamberlin.
