Landsat 7 ETM+ satellite image (Path 79, Row 23) of the Island of Four Mountains in the Central Aleutian Islands of Alaska. This is a thermal band image where the lighter shades indicate higher thermal energy being received by the satellite. The brighter linear feature on the western side of Mt. Cleveland is the main 2001 lava flow from the eruption. Another brighter area on the very western shoreline, that is the brightest on the image, is the delta formed from the 2001 eruption.
