Mendenhall Glacier is a glacier about long located in Mendenhall Valley, about 12mi from downtown Juneau in the southeast area of the U.S. state of Alaska. The glacier and surrounding landscape is protected as part of the 5815acre Mendenhall Glacier Recreation Area, a federally designated unit of the Tongass National Forest.
The Juneau Icefield Research Program has monitored the outlet glaciers of the Juneau Icefield since 1942, including Mendenhall Glacier. The glacier has also retreated 1.75mi since 1929, when Mendenhall Lake was created, and over 2.5mi since 1500. The end of the glacier currently has a negative glacier mass balance and will continue to retreat in the foreseeable future.
Given that average yearly temperatures are currently increasing, and the outlook is for this trend to continue, it is actually possible that the glacier might experience a period of stabilization or slight advance during its retreating march. This is because increasing amounts of warm, moist air will be carried up to the head of the icefield, where colder ambient temperatures will cause it to precipitate as snow. The increased amount of snow will feed the icefield, possibly enough to offset the continually increasing melting experienced at the glacier's terminus. However, this interesting phenomenon will fade away if temperatures continue to climb, since the head of the glacier will no longer have cold enough ambient temperatures to cause snow to precipitate.
It was originally known as Sitaantaago or Aak'wtaaksit, also Latinized as Aakwtaaksit, by the Tlingit. The glacier was named Auke Glacier by naturalist John Muir for the Tlingit Auk Kwaan band in 1888. In 1891 it was renamed in honor of Thomas Corwin Mendenhall. It extends from the Juneau Icefield, its source, to Mendenhall Lake. Using our online itinerary creator, Juneau attractions like Mendenhall Glacier can form part of a personalized travel itinerary.

  • This is just beautiful. Take the shuttle, $45 each round trip. (Glacier Shuttles) plan around 2-3 hours from port and back. Take the trail, more like a walking road. Go to the falls about 2 miles...

  • Visitor center was great, weather was stellar, but the East Glacier Loop trail was the highlight. Hiked with son and his dog on this 3 mile/750' elevation trail with great views along the way...
