Mount Chamberlin was long thought to be a contender for the honor of highest peak in the Brooks Range. The 1956 USGS topographic map has its elevation at 9020 feet, higher than the 1983 USGS elevation of Mount Isto 25 miles to the east. However, differential GPS surveys from 2014 show that Mount Isto is about 70 feet higher, leaving Mount Chamberlin as the second highest peak in the area.
The new surveyed heights of Chamberlin and Isto have not yet been released to the public--only the height differential was announced.
Chamberlin is still a very attractive ascent option for Brooks Range climbers, since bush pilots can often land at nearby Peters Lake, site of a research station.
