Mount Gerdine is located 90 miles (145 km) west-northwest of Anchorage in the Tordrillo Mountains which are a subrange of the Alaska Range.

The remote glaciated Gerdine ranks as the second-highest peak in the Tordrillo Mountains,[3] and 201st-highest summit in Alaska.

The mountain's name honors Thomas Golding Gerdine (1872–1930), U.S. Geological Survey topographic engineer who made several reconnaissance trips in Alaska at the end of the 19th century.

Gerdine's summit was made on May 5, 1963, by Rod Wilson, Lowell Thomas Jr., Dr. George Wichman, Paul Crews Jr., and Paul Crews Sr.[5] Based on the Köppen climate classification, Mount Gerdine is located in a tundra climate zone with long, cold, snowy winters, and cool summers.
