Mount Muir is a prominent glaciated mountain summit located in the Chugach Mountains, in Chugach National Forest, in the U.S. state of Alaska, approximately north of in Prince William Sound.
The mountain was named in 1908 by geologists Grant and Higgins and officially adopted in 1910 by the United States Geological Survey, probably after of the American naturalist, conservationist and writer John Muir (1838âÂÂ1914), who visited the Alaska area four times, including as a member of the 1899 Harriman Alaska expedition that explored this immediate area. The first recorded ascent of Mount Muir was completed in April 2014 by climbers Ryan Fisher and Nathan Lane via the north face.
Mount Muir is situated in the northern reaches of the Chugach Mountains, near the edge of the Chugach National Forest. It serves as the origin point for several glaciers, including the , Baker Glacier, Detached Glacier, and the Colony Glacier. The Colony Glacier flows northward, draining into Inner Lake George, while the others are hanging glaciers on the mountain's southern slopes, descending toward Harriman Fjord.

Based on the Köppen climate classification, Mount Muir is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Temperatures can drop below âÂÂ20 ðC with wind chill factors below âÂÂ30 ðC. 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.
Mount Muir is prominently visible from Harriman Fjord, accessible only by sea from Whittier (approximately by sea or by air) or Valdez (over by sea). Distances are derived from Google Earth. During the tourist season, boat excursions from Whittier offer views of the Surprise Glacier and the Penniman, Baker, and Detached Glaciers on the mountain's slopes.
