Nature
Sinclair Mountain is a prominent summit in southeastern Alaska’s Boundary Ranges of the Coast Mountains, rising a little over 6,800 feet on Tongass National Forest land near Skagway. Though modest by Alaska standards, it climbs sharply from the entrance to Chilkoot Inlet, giving it striking local relief above the water. Established as a name in 1920, it honors Cephas Hempstone Sinclair, a hydrographic and geodetic engineer who spent 47 years in field service with the United States Coast and Geodetic Survey. Its subarctic climate brings heavy rain, snow, severe cold, and glaciers on its north, south, and east sides. The first recorded ascent came in mid-June 1973.
