Mendenhall Glacier is a glacier about 12 miles long located in Mendenhall Valley, about 12 miles from downtown Juneau in the southeast area of the U.S. state of Alaska. Originally known as Sitaantaagu (“the Glacier Behind the Town”) or Aak’wtaaksit (“the Glacier Behind the Little Lake”) by the Tlingits, the glacier was named Auke (Auk) Glacier by naturalist John Muir for the Tlingit Auk Kwaan (or Aak’w Kwaan) band in 1888. In 1891 it was renamed in honor of Thomas Corwin Mendenhall.
