This steep-sided blocky lava flow originated from Potato Butte, twin cinder cones located immediately north of Lassen Volcanic National Park.  The lava flows originated from vents that overlie the western side of the Hat Creek valley and traveled primarily to the north and west of the cones.  The flows, once thought to be of possible Holocene age, have been dated at 65,000-75,000 years old. Photo by Lee Siebert, 1998 (Smithsonian Institution).
