| Contextual Notes | Mendenhall Glacier is located 13 miles from downtown Juneau. In the mid-1700s, Mendenhall Glacier reached its point of maximum advance, and its terminus rested almost 2.5 miles down valley from its present position. Mendenhall Glacier started retreating in the mid-1700s because its annual rate of melt began to exceed its annual total accumulation. The icefield's snowfall perpetually creates new glacial ice for Mendenhall Glacier and this ice takes 200-250 years to travel from the Juneau Icefield to Mendenhall Lake. Water depth at the glacier's terminus is 220 feet. Thomas Corwin Mendenhall (1841-1924) served as Superintendent of the U.S. Coast and Geodetic Survey from 1889 to 1894. A noted scientist, Mendenhall also served on the Alaska Boundary Commission that was responsible for surveying the international boundary between Canada and Alaska. In 1892, this glacier was renamed to honor Mendenhall. Naturalist John Muir first named the glacier Auke Glacier in 1879 after the Aak'w Kwaan of the Tlingit Indians.
