BackgroundThe Potato Butte cinder cone and lava field, which includes the prominent Hat Creek lava flow that traveled nearly 30 km from a fissure vent near the town of Old Station, lies immediately north of the Lassen volcanic center. Some flows are younger than the Hat Creek flow, which was initially considered to be Holocene, perhaps as young as a few thousand years (Anderson 1940), although later dating showed the the flow to be about 30,000 years old. The younger Potato Butte lavas, once considered to be of latest Pleistocene or early Holocene age, have been K-Ar dated at 65,000-75,000 years old (Clynne et al. 2000). Directly west of Potato Butte is the 61,000-year-old symmetrical lava cone of Sugarloaf Peak.
