The effects of differential erosion are dramatically seen in this aerial view of two Alaskan volcanoes.  Isanotski volcano in the foreground, sometimes referred to as "Ragged Jack," has been extensively dissected by glaciers that have excavated steep walls separated by narrow ridges.  The symmetrical Shishaldin volcano in the background is sometimes referred to as the Mount Fuji of the Aleutians.  In contrast to Isanotski, Shishaldin is one of Alaska's most active volcanoes.  Frequent eruptions maintain the young, constructional profile of the volcano. Copyrighted photo by Katia and Maurice Krafft, 1978.
