Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Potato Butte. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Potato Butte page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

Photo Gallery

Potato Butte, the forested cinder cone at the left-center, is seen here from the rim of the Hat Creek vent with snow-covered Lassen Peak in the background. The Potato Butte cinder cones and lava flows were erupted around 65,000-75,000 years ago. The prominent 30,000-year-old Hat Creek lava flow traveled nearly 30 km from a fissure vent near the town of Old Station. An undated, but younger-looking flow originated from a cinder cone near West Prospect Peak, west of Potato Butte.

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.

The green Manzanita-covered slope in the foreground is part of the circular rim of South Potato Butte, one of two cinder cones forming Potato Butte. The two cinder cones fed youthful-looking lava flows down the Hat Creek graben. Snow-covered Lassen Peak rises in the distance, with the Chaos Crags lava dome complex to its right.

The two small Pleistocene cinder cones in the Hat Creek valley, just to the right of the two highest trees in the foreground, are viewed here from West Prospect Peak. The cones are among a series of young volcanic vents located north of Lassen Peak and fed lava flows that traveled to the north (right). Three forest-covered Pleistocene volcanoes can be seen in the background, Sugarloaf (above the green meadow in the center), Logan Mountain (left-center), and Burney Mountain (right-center). Snow-capped Mount Shasta is at the upper right.

North Potato Butte, seen here from South Potato Butte, is a 65,000-75,000-year-old cinder cone located in the Hat Creek valley north of Lassen Peak. The Potato Butte cinder cones are among a series of small Quaternary basaltic volcanic vents located between Lassen and Medicine Lake volcanoes.
