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, new accurate GPS surveys from 2014 show that Chamberlin has an elevation of only 8901 feet, making it the third highest peak in the range, 75 feet lower than Mount Isto and 16 feet lower than Mount Hubley.
Chamberlin is still a very attractive ascent option for Brooks Range climbers. It is a significant peak with a large prominence of over 4000 feet, and bush pilots can often land at the nearby Peters Lake research station, making access easy by North Slope standards.
