An aerial view of the SE coast of Semisopochnoi Island shows Sugarloaf peak (left-center) with a flank cone (foreground) that was the source of one of the more recent lava flows. Sugarloaf erupted outside the southern margin of an 8-km-wide caldera on Semisopochnoi. Mount Cerberus was constructed within the caldera and is on the left horizon. Pre-caldera Ragged Top is to the right.
