The Potato Butte cinder cone and lava field, including the 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 flow to be about 30,000 years old. The younger Potato Butte lavas, once considered to be late Pleistocene or early Holocene, 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 Sugarloaf Peak lava cone.
