Glaciers & Glacial Features

A glacier inside the Mt Katmai caldera that has formed as a result of Novarupta's eruption in 1912

After the volcanic activity ceased on Mount Katmai, a glacier formed on the inside wall of the caldera. This glacier, which now extends down to the edge of the caldera lake, is perhaps the only glacier in the world having a known date of origin. Glacial features within Katmai preserve a complete sequence of Wisconsin and Recent (Alaskan) glaciation.

Did You Know?
Several glaciers near Katmai's Valley of Ten Thousand Smokes are currently advancing because of thick layers of ash, deposited by the 1912 Novarupta eruptions, acting as insulation for the glaciers and preventing melting as quickly while they flow down valley.
