The glacier has also retreated 1.75 miles (2.82 km) since 1929, when Mendenhall Lake was created, and over 2.5 miles (4.0 km) since 1500. The end of the glacier currently has a negative glacier mass balance and will continue to retreat in the foreseeable future.
A glacier with a sustained negative balance loses equilibrium and retreats. A sustained positive balance is also out of equilibrium and will advance to reestablish equilibrium. Currently, nearly all glaciers have a negative mass balance and are retreating. [13] Glacier retreat results in the loss of the low-elevation region of the glacier.

Previous bridges across the Mendenhall River, at or near the same spot, were constructed in 1903, 1919 and 1931. [4] It was entered into the United States Geological Survey's Geographic Names Information System on March 31, 1981. [1] The Brotherhood Bridge was slated for replacement, with widening and other improvements, in 2012.
