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.
