Pahoehoe lava, characterized by its smooth, rope-like appearance, is one of three types of lava. Pahoehoe's ropy surface forms when a thin skin of cool lava is shoved into folds by hot, more-fluid lava just below the surface. This sample was found in Craters of the Moon National Monument, Idaho. Pahoehoe is pronounced Pa-hoy-hoy.
