Mount Wrangell, a 4,317-m (14,163 ft)-high andesite
shield volcano is visible to the left on the skyline; it is
the only volcano in the Wrangell Mountains to have had
documented historical activity. This consisted of several
minor, possibly phreatic eruptions in the early 1900's.
Mount Drum, 3,661 m (12,011 ft) high, is the westernmost
volcano in the Wrangell volcanic field, and is visible to
the right on the skyline. The Copper River is in the
foreground. View is to the southeast. Photograph by D.
