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. The deposit probably formed when a lava flow high on the flank of the volcano collapsed and tumbled down the side of the volcano, all the way to the sea.
