Fourpeaked volcano to the upper left is one of a group of volcanoes NE of Katmai National Park, beyond the 2.5-km-wide Kaguyak caldera in the foreground. Much of the surface is hidden beneath Fourpeaked Glacier; the few exposed outcrops are lava flows interlayered with volcanic agglomerate. Deposits near the summit are extensively hydrothermally altered.
