Mount Muir is a prominent 7,605-foot (2,318 m) glaciated mountain summit located in the Chugach Mountains, in Chugach National Forest, in the U.S. state of Alaska. Although modest in elevation, relief is significant since the southern aspect of the mountain rises from the sea-level Harriman Fiord of Prince William Sound. The mountain's name was officially adopted in 1910 by the United States Geological Survey, probably after conservationist John Muir (1838-1914) who visited the Alaska area four times,^[3] including as a member of the 1899 Harriman Alaska expedition that explored this immediate area.

Climate

Based on the Köppen climate classification, Mount Muir is located in a subarctic climate zone with long, cold, snowy winters, and mild summers.^[4] Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Baker Glacier, Penniman Glaciers, and Detached Glacier on its south slopes, and tributaries of the Colony Glacier on its north, east, and west aspects. May and June are the best months for climbing in terms of favorable weather.
