Mt. Finch, the most recently active vent at Fisher volcano.  Brightly colored areas are regions of hydrothermal alteration caused by fumarolic activity.  The eastern caldera rim can be seen it the background as a subtle dark ridge.  Light colored areas just inside the eastern caldera wall are phreatomagmatic surge deposits that cap prominent topographic features in the area.  View is to the east.
