How much has the Mendenhall Glacier receded?
Since installing a camera at Mendenhall in 2007, Extreme Ice Survey says the glacier has retreated more than 1,830 feet — about one-third of a mile. Its abnormally fast retreat and deflation shows the effects of climate change in action, according to Extreme Ice Survey.
Is Mendenhall Glacier retreating?
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….

Can glaciers move uphill?
One significant different between the flow of ice and the flow of water is this: a river is pulled downwards by gravity. This happens to glaciers too, when flowing downhill; but glaciers are also pushed by the pressure behind them: as a result, glaciers can and do flow uphill.

about 3,000 years ago
The Mendenhall Glacier and many others along the Southeast Alaska coast are remnants of the Little Ice Age which began about 3,000 years ago. Warm, moist air flowing in from over the ocean cools as it rises above the 5,000 foot coastal mountains and drops its moisture as snow.
