This view, across the Copper River to the SE, shows Mount Sanford (left) and Mount Wrangell (right). The dissected Sanford shield volcano has a broad, rounded top that is surrounded by steep-walled glacial cirques. Most of the volcano formed during the Pleistocene. Eruptive activity at Wrangell has continued into historical time.
