Map of Long Valley Caldera Early winter in Long Valley, 2017. Long Valley Caldera is a depression in eastern California that is adjacent to Mammoth Mountain.The valley is one of the Earth's largest calderas, measuring about 20 mi (32 km) long (east-west), 11 mi (18 km) wide (north-south), and up to 3,000 ft (910 m) deep.
According to USGS risk assessment of the volcanoes in CalVO's region, the following volcanoes were ranked "very high threat potential". [4] Mount Shasta in far-northern California, north of Redding; Lassen Volcanic Center in Lassen Volcanic National Park; Long Valley Caldera in eastern California; Mono-Inyo Craters. These were ranked "high ...
Many geological features in Western United States have a Northeastern orientation, the North American craton motion has the same orientation as well. [1] For example: the Trans-Challis fault zone, Idaho; the Snake River in Oregon; the Garlock Fault, California; the Colorado River in Utah; the Colorado Mineral Belt; Crater Flat-Reveille Range-Lunar Crater lineament, the Northwestern Nevada ...
Mammoth Mountain is a lava dome complex in Mono County, California. It lies in the southwestern corner of the Long Valley Caldera [6] and consists of about 12 rhyodacite and dacite overlapping domes. [7] These domes formed in a long series of eruptions from 110,000 to 57,000 years ago, building a volcano that reaches 11,059 feet (3,371 m) in ...
The Bishop Tuff is a welded tuff which formed 764,800 ± 600 years ago as a rhyolitic pyroclastic flow during the approximately six-day eruption that formed the Long Valley Caldera. [1] [2] [3] Large outcrops of the tuff are located in Inyo and Mono Counties, California, United States. Approximately 200 cubic kilometers of ash and tuff erupted ...
A long-quiet yet massive super volcano, dubbed the "Long Valley Caldera," has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so.
Yellowstone National Park is on three partly covered caldera complexes. The Long Valley Caldera in eastern California is also a complex volcano; the San Juan Mountains in southwestern Colorado are formed on a group of Neogene-age caldera complexes, and most of the Mesozoic and Cenozoic rocks of Nevada, Idaho, and eastern California are also ...
The Long Valley to Mono Lake region is one of three areas in California that are in the United States Geological Survey's volcanic hazards program. [ note 2 ] [ 28 ] : 52 These areas are in the program because they have been active in the last 2,000 years and have the ability to produce explosive eruptions.
