The Coso volcanic field is located east of the Sierra Nevada Range at the western edge of the Basin and Range province, California. It consists of 38 old rhyolitic lava domes and basaltic cinder cones covering a 400 sq km area. volcano is located 200 km north of Los Angeles, California.
Eruptions in this area over the past 4 million years produced 35 km3 of lava, the youngest eruptions are probably from the basaltic Volcano Peak cinder cone and occurred more than 33,000 years ago.
