(volcanic field & cinder cones)
|The Amboy volcanic field covers an area of 70 km2 between Bagdad Dry Lake to the west and Bristol Dry Lake to the east in the Mojave Desert, California. It contains mainly pahoehoe lava flows. Amboy crater proper is a prominant cinder cone in the NE of the lava field. [more]|
|Brushy Butte is a small, poorly studied shield volcano immediately east of Timbered Crater maar, and south-southeast of the Medicine Lake Highlands in northern California, USA. [more]|
|Clear Lake volcanic field lies in the northern Coast Ranges, California, ca. 135 km north of San Francisco. The volcanic field consists of lava dome complexes, cinder cones, and maars of basaltic-to-rhyolitic composition. Mount Konocti, a dacitic lava dome on the south shore of C... [more]|
|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, Cali... [more]|
|Eagle lake is a volcanic field at the junction of the Sierra Nevada, Cascades, and Basin Range in California, USA. It contains 15 small cinder cones, fissures and lava flows. [more]|
|Golden Trout Creek|
|The Golden Trout Creek volcanic field consists of a group of cinder cones and lava flows in the Toowa Toowa valley of the Sierra Nevada, California, about 25 km south of Mount Whitney.
Toowa valley is a broad and open valley about 8600 feet high, dotted with cones rising 10... [more]
|Inyo Craters are a 12-km long field of lava domes at the eastern margin of the Sierra Nevada, California, near the town of Mammoth and south of the similar Mono Craters field. The field contains silicic 6 lava domes, lava flows, and 15 explosion craters (maars) that last erupted ... [more]|
|Lassen (or Lassen Peak) volcano in northern California is located at the southern end of the Cascade Range. Besides Mt St. Helens, it is the only volcano in the contiguous US that erupted in the 20th century.
Lassen's summit complex is a lava dome that rises 2,000 feet (610... [more]
|Lavic Lake, a dry lakebed in the Mojave desert, California, is a volcanic field of 4 cinder cones, 3 of which are in the Lavic Lake area and a fourth in the Rodman Maountains 20 km to the west.
Pisgah crater is the main feature, a prominent 100 m high cinder cone north of L... [more]
|The large 17 x 32 km Long Valley caldera east of the central Sierra Nevada Range, California, is the result of a giant explosive eruption that happened about 760,000 years ago and formed the widespread and voluminous Bishop Tuff.
The caldera has been showing unrest in recen... [more]
|Mammoth Mountain is a lava-dome complex on the SW rim of Long Valley caldera, California. Despite its close geographic relation, it is believed that it has its own magma chamber different from the ones underlying Long Valley caldera and the Inyo craters. [more]|
|Medicine Lake is a large shield volcano in northeastern California about 50 km (30 mi) northeast of Mount Shasta, rising about 1,200 metres (3,900 ft) above the Modoc Plateau to an elevation of 2,376 metres (7,795 ft). It contains a 12 km x 7 km wide caldera.
The shield vol... [more]
|The Mono Craters are an elongated, 17 km long group of lava domes, cinder cones and maars on the eastern side of the Sierra Nevada between Mono Lake and Long Valley caldera, California. The last eruption at the Mono Craters took place about 600 years ago, nearly contemporaneously... [more]|
|The Mono Lake volcanic field east of Yosemite National Park and north of the Mono Craters in central eastern California is a series of cinder cones in Mono Lake and on its shore. It is one of the most recently active volcanoes in California, the last eruptions having occurred at ... [more]|
|Mt Shasta in Siskiyou County, northen Californian, is the second largest volcano of the Cascade Range. Mount Shasta rises majestically nearly 10,000 ft (3000 m) above the surrounding terrain as it is not connected to any nearby mountain. It has an estimated volume of 350 km3 whic... [more]|
|The Salton Buttes volcanic field consist of 5 small rhyolitic lava domes built above sediments of the Colorado River delta within the Salton Sea geothermal field, located at the SE margin of the Salton Sea, California. [more]|
|Silver Lake is one of many volcanic fields northern California. It consists of 3 small explosion craters The volcano consists of 3 small cinder cones and lava lakes. The craters contain lakes: Silver Lake, Author Lake, and Buckhorn Lake. [more]|
|Tumble Buttes is a volcanic field in northern California, consisting of several cinder cones that had been last active about 15,000 years ago. A well-known feature is Devils Rock Garden, a blocky lava flow which extends south of the volcano. [more]|
|Twin Buttes in northern California is a volcanic field of cinder cones, lava flows and domes. [more]|
(explosion craters (maars))
|Ubehebe Craters volcano is a group of maars (explosion craters) located at the western margin of Tin Mountain, California, in the northern end of Death Valley. The craters were thought to have last erupted about 6000 years ago, but a recent study suggests that some activity could... [more]|
