Photograph by D.A. Swanson on 13 December 1998

Person sitting on entrail pahoehoe along the Chain of Craters Road in Hawai`i Volcanoes National Park, Kilauea Volcano, Hawai`i.

Pahoehoe entrail
Named after the texture of an animal's intestines entrail pahoehoe best forms when pahoehoe flows down a steep slope. It is usually found on the sides of rootless vents, such as hornitos and ruptured tumuli. On the south flank of Kilauea the most striking examples occur where pahoehoe oozed down steep scarps in the Hilina fault system.
