Big Pine volcanic field is a volcanic field in Inyo County, California. The volcanic field covers a surface area of 500 square kilometres (190 sq mi) within the Owens Valley east of the Sierra Nevada and consists of lava flows, one rhyolitic coulee and about 40 volcanic vents including cinder cones. Some vents are simple conical cinder cones while others are irregular scoria cones. Glaciers and former lakes have modified lava flows. Volcanic activity in the field commenced 1.2 million years ago and was controlled by a number of faults which cross the valley. Activity continued into the Pleistocene with the youngest eruption generating cones and several lava flows about 17,000 years ago. A major road and the Los Angeles Aqueduct would be threatened if volcanic activity restarted at Big Pine.
