Unidentified man sits on a rock on the "Arizona" side of the Colorado River. Inscription with image reads: "Cross section of a lava flow jilting a former channel of the Colorado River in Lower Grand Canyon, approximately 19 miles east of Pierce's [Pearce] Ferry. Under our geological program, studies of this flow are being made before the rising of Lake Mead obliterated portions of it from view."
