This lava flow is part of the Lavic Lake Volcanic Field in California's Mojave Desert. Mono Lake Volcanic Field The Mono Lake volcanic field east of Yosemite National Park and north of the Mono Craters consists of vents within Mono Lake and on its north shore. As of 2008, seismic monitoring is the most used technique for volcano surveillance. Volcanic Fields. Lavic Lake The Lavic Lake volcanic field was considered to contain four Holocene cinder cones, three in the Lavic Lake area and a fourth in the Rodman Mountains 20 km to the west (Miller 1989). The Eagle Lake volcanic field occupies the junction of the Cascades, Sierra Nevada, and Basin and Range geologic provinces, and consists of 15 cinder cones and basaltic lava flow vents within a larger Quaternary basaltic field. Of the three volcanoes discussed on this page, it is located the nearest to Southern California's city areas, being about 23 miles (37 km) from Barstow, and 50 miles (80 km) from San Bernardino. The lava field, at 1,495 m (4,905 ft) elevation, and its cones can be seen from historic Route 66 and from Interstate 40, between Barstow to the west and Needles to the east, and is located southeast of Ludlow, California. These receivers are part of the 46 instruments that make up the network monitoring Long Valley Caldera. The Lavic Lake volcanic field contains four late Pleistocene cinder cones, three in the Lavic Lake area and a fourth in the Rodman Mountains 20 km (12.4 mi) to the west.Pisgah Crater, a 100-m-high (328 ft) cinder cone, is the most prominent feature of the basaltic lava field. Pisgah Crater, a 100-m-high cinder cone, is the most prominent feature of the field. As magma moves through the earth, it displaces and fractures rock along the way. It's the most accessible of the the Lavic Lake volcanic field's four cinder cone volcanoes in the area. Attribution: California Volcano Observatory, Clear Lake Volcanic Field, Coso Volcanic Field, Lassen Volcanic Center, Long Valley Caldera, ... A group of scientists at CalVO have recently begun a new investigation of the Clear Lake Volcanic Field (CLVF), a seismically and geothermally active volcanic system located just ~150 km (93 miles) north of the San Francisco Bay Area. There may have been activity at this site as recent as 2,000 years ago; however others believe the last eruption occurred as early as 20,000 to 50,000 years ago. The Lavic Lake volcanic field is a volcanic field with extinct cinder cones in the Mojave Desert, in San Bernardino County, California, United States.
