This view looks south across the caldera from the north rim of Aniakchak. The prominent dark peak on the skyline (left) is Black Nose, a remnant of pre-caldera volcaniclastics. A pumice-covered glacier and associated moraine is in the distance against the caldera wall. Surprise Lake once covered a much larger part of the caldera floor before catastrophically draining through a notch in the east caldera rim.
