Caption:Part of a ~6 m (20 feet) thick section of ash and lapilli falls from Cleveland and nearby volcanoes, exposed in a gully on the southeast flank of the volcano. We will be analyzing some of the ashes and soils from this section to begin to understand eruption frequency in the Islands of Four Mountains. Measuring tape is 1 m 3.3 feet) long. 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.

Caption:Kirsten Nicolaysen, Whitman College and Islands of Four Mountains Project leader, leans on a recently emplaced lava block carried down the flank of Cleveland volcano in a block and ash flow.
