Sable Mountain is located in the Alaska Range and in Denali National Park and Preserve. It is situated 3.43 miles (5.52 km) southwest of Igloo Mountain at Sable Pass near mile 40 of the Park Road which traverses the mountain's southern slope. Precipitation runoff from the mountain drains west to the Toklat River and east to the Teklanika River. Topographic relief is significant as the summit rises 2,000 feet (610 meters) above Tattler Creek in one mile (1.6 km). The mountain's name was shown on a 1916 U.S. Geological Survey document and the toponym has been officially adopted by the United States Board on Geographic Names.

Based on the Köppen climate classification, Sable Mountain is located in a tundra climate zone with long, cold, snowy winters, and mild summers. Winter temperatures can drop below −20 °F with wind chill factors below −30 °F. The months May through June offer the most favorable weather for climbing or viewing.
