Photo Gallery

Herbert Island, capped by the snow-covered peak in the right foreground, is a classic, symmetrical stratovolcano with a 2-km-wide summit caldera that is breached to NW. No historical eruptions have been recorded from 1280-m-high Herbert volcano, which, like many other Aleutian volcanoes, has not been studied geologically. This June 23, 1987, view from the WSW shows a steam plume originating from conical Cleveland volcano in background, whose slopes are darkened by ashfall from an eruption that began on June 19.
