Coso Range
The Coso Range of eastern California is located immediately south of Owens Lake, east of the Sierra Nevada, and west of the Argus Range. The southern part of the range lies in the restricted Naval Air Weapons Station China Lake and the northern part of the range is designated as the Coso Range Wilderness. The mountains include Coso Peak, at above sea level, as well as Silver Peak and Silver Mountain, both more than in height. The range is underlain principally by Mesozoic granitic rocks that are partly veneered by upper Cenozoic volcanic rocks of the Coso Volcanic Field. The volcanic units (in apparent decreasing age) include (1) widespread basaltic flows, (2) dacitic flows and tuff, and (3) rhyolitic domes and flows and basaltic cones and flows. These volcanic rocks are encompassed by an oval-shaped zone of late Cenozoic ring faulting that measures about east to west and north to south and that defines a structural basin. Most of the Coso Range and a slice of the adjacent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inyo County, California
Inyo County () is a county in the eastern central part of the U.S. state of California, located between the Sierra Nevada and the state of Nevada. In the 2020 census, the population was 19,016. The county seat is Independence. Inyo County is on the east side of the Sierra Nevada and southeast of Yosemite National Park in Central California. It contains the Owens River Valley; it is flanked to the west by the Sierra Nevada and to the east by the White Mountains and the Inyo Mountains. With an area of 10,192 square miles (26,397 km2), Inyo County is the second-largest county by area in California, after San Bernardino County. Almost one-half of that area is within Death Valley National Park. However, with a population density of 1.8 people per square mile, it also has the second-lowest population density in California, after Alpine County. History Present-day Inyo county has been the historic homeland for thousands of years of the Mono, Timbisha, Kawaiisu, and Nort ...

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Mountain Ranges Of The Mojave Desert
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain a ...

Fossil Falls
The Fossil Falls is a unique geological feature, located in the Coso Range of California in the United States. Volcanic activity in the mountain range, along with meltwater from glaciers in the nearby Sierra Nevada, played a role in the creation of the falls. They are located near the community of Little Lake, off US 395 (at a red cinder cone called "Red Hill") on Cinder Road to Red Hill, with signs to Fossil Falls. Geology During the last ice age, glaciers formed in the Sierra Nevada. Meltwater from the glaciers pooled into large lakes, including Owens Lake and the Owens River. The river traveled through to Indian Wells Valley, and its course was diverted several times by volcanic activity. The falls were formed when the river was forced to divert its course over a basalt flow, polishing and reshaping the rock into a variety of unique shapes and forms. All the lava flows at Fossil Falls are basaltic. The Coso Volcanic Field brought flows from the north east and later Red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ridgecrest, California
Ridgecrest is a city in Kern County, California, United States, along U.S. Route 395 in the Indian Wells Valley in northeastern Kern County, adjacent to the Naval Air Weapons Station China Lake (NAWS, or China Lake). It was incorporated as a city in 1963. The population was 27,959 at the 2020 census, up slightly from 27,616 at the 2010 census.

Channel Islands Of California
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group. The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture.

Coso Rock Art District
Coso Rock Art District is a rock art site containing over 100,000 Petroglyphs by Paleo-Indians and/or Native Americans. The district is located near the towns of China Lake and Ridgecrest, California. Big and Little Petroglyph Canyons were declared a National Historic Landmark in 1964. In 2001, they were incorporated into this larger National Historic Landmark District. There are several other distinct canyons in the Coso Rock Art District besides the Big and Little Petroglyph Canyons. Also known as Little Petroglyph Canyon and Sand Tanks, Renegade Canyon is but one of several major canyons in the Coso Range, each hosting thousands of petroglyphs (other locations include Haiwee Springs, Dead End Canyon, and Sheep Canyon). The majority of the Coso Range images fall into one of six categories: bighorn sheep, entopic images, anthropomorphic or human-like figures (including animal-human figures known as pattern-bodied anthopomorphs), other animals, weapons & tools, and "medicine ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magma Chamber
A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. If the magma finds a path to the surface, then the result will be a volcanic eruption; consequently, many volcanoes are situated over magma chambers. These chambers are hard to detect deep within the Earth, and therefore most of those known are close to the surface, commonly between 1 km and 10 km down. Dynamics of magma chambers Magma rises through cracks from beneath and across the crust because it is less dense than the surrounding rock. When the magma cannot find a path upwards it pools into a magma chamber. These chambers are commonly built up over time, by successive horizontal or vertical magma injections. Influx of new magma causes reaction of pre-existing crystals and the pressure in the chamber to increase. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
