Tana volcano as seen from Applegate Cove. The westernmost (nearest in this view) peak of Tana is cut by a fissure vent that produced a series of explosion craters, lava flows, and cinder cones. Photo taken during the 2014 field season of the Islands of Four Mountains multidisciplinary project, work funded by the National Science Foundation, the USGS/AVO, and the Keck Geology Consortium.
