In this photo, three scientists are examining a large pile of slabs of lava. One man wearing a blue button-down shirt and khaki hat is perched on an upper level of the slabs at left, a young woman with braided hair has one foot perched on a slab like a certain pirate at middle right, and a tall bald man in a black shirt stands on top of a pavement of hexagonal lava columns at far right. In the background, scrubby pine trees and bushes grow atop the lava.
