Sentinel Dome
Sentinel Dome is a granite dome in Yosemite National Park, United States. It lies on the south wall of Yosemite Valley, southwest of Glacier Point and northeast of Profile Cliff. Sentinel Dome is known for a Jeffrey Pine that grew from its peak (see photograph). The pine was photographed as early as 1867 by Carleton Watkins, and was the subject of a well-known photograph by Ansel Adams. The tree died during the drought of 1976, but remained standing until August 2003. History The original Native American name of Sentinel Dome, in the Southern Sierra Miwok language, was "Sakkaduch". The Bunnell survey named it "South Dome", but the Whitney survey renamed it Sentinel Dome (from its likeness to a watch-tower). The view from the top offers a 360 degree view of Yosemite Valley and surroundings. One can see Half Dome, El Capitan, Yosemite Falls, North Dome, Basket Dome, and much more. Sentinel Dome provides a 360 degree view of the night sky and it and nearby Glacier Point are po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yosemite National Park
Yosemite National Park ( ) is an American national park in California, surrounded on the southeast by Sierra National Forest and on the northwest by Stanislaus National Forest. The park is managed by the National Park Service and covers an area of and sits in four countiescentered in Tuolumne and Mariposa, extending north and east to Mono and south to Madera County. Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, meadows, glaciers, and biological diversity. Almost 95 percent of the park is designated wilderness. Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The geology of the Yosemite area is characterized by granite rocks and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and tilted to form its unique s ...

Valley And Sierra Miwok
The Plains and Sierra Miwok were once the largest group of California Indian Miwok people, indigenous to California. Their homeland included regions of the Sacramento Valley, San Joaquin Valley, and the Sierra Nevada. Geography The Plains and Sierra Miwok traditionally lived in the western Sierra Nevada between the Fresno River and Cosumnes River, in the eastern Central Valley of California. As well as in the northern Sacramento–San Joaquin River Delta region at the confluences of the Cosumnes River, Mokelumne River, and Sacramento River. In the present day, many Sierra Miwok live in or close to their traditional territories and Indian rancherias, including at: *Buena Vista Rancheria *Chicken Ranch Rancheria *Jackson Rancheria *Sheep Ranch Rancheria *Shingle Springs Rancheria *Tuolumne Rancheria *Wilton Rancheria Culture The Plains and Sierra Miwok lived by hunting and gathering, and lived in small local tribes, without centralized political authority. They are skilled at b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite Domes Of Yosemite National Park
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly always ...

Mountains Of Mariposa County, California
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 and ...

Taft Point
Taft Point is a viewpoint in Yosemite National Park west of Glacier Point. It offers wide views of Yosemite Valley, Yosemite Falls and El Capitan. The main attraction of Taft Point is the giant fissures in the mile-high granite rock. The fissures are breaks and cracks in the mountain that drop directly down to the valley floor at some points. The point is named after 27th President of the United States William Howard Taft, who, according to newspaper accounts, came across the point when he visited Yosemite for three days hosted by John Muir in October 1909. The two hiked from nearby Glacier Point down to the valley floor. President Taft planned the trip by horseback, but the horses brought for his use were all too small for his 300 plus pounds. His staff set luncheon for the president's party during the hike, including fried chicken. The lunch spot may have been near the flat ledge that has since become known as Taft Point. Taft wrote of his hike, "While I am tired from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yosemite Falls
Yosemite Falls is the highest waterfall in Yosemite National Park, dropping a total of from the top of the upper fall to the base of the lower fall. Located in the Sierra Nevada of California, it is a major attraction in the park, especially in late spring when the water flow is at its peak. Triple fall The falls consist of three drops (sections): Upper Yosemite Fall The plunge comprises over half the total drop. Trails from the valley floor and down from other park areas outside the valley lead to both the top and base of Upper Yosemite Fall.<3 The upper fall is formed by the swift waters of Yosemite Creek, which, after meandering through Eagle Creek Meadow, drop over the edge of a hanging valley in a spectacular and deafening show of force.

El Capitan
El Capitan ( es, El Capitán; "the Captain" or "the Chief") is a vertical rock formation in Yosemite National Park, on the north side of Yosemite Valley, near its western end. The granite monolith is about from base to summit along its tallest face and is a popular objective for rock climbers. Naming The formation was named "El Capitan" by the Mariposa Battalion when they explored the valley in 1851. ''El Capitán'' ("the captain", "the chief") was taken to be a loose Spanish translation of the local Native American name for the cliff, “Tutokanula” or "Rock Chief" (the exact spelling of Tutokanula varies in different accounts as it is a phonetic transcription of the Miwok language). The "Rock Chief" etymology is based on the written account of Mariposa Battalion doctor Lafayette Bunnell in his 1892 book. Bunnell reports that Ahwahneechee Chief Tenaya explained to him, forty-one years earlier, in 1851, that the massive formation, called Tutokanula, could be translated as ...

Half Dome
Half Dome is a granite dome at the eastern end of Yosemite Valley in Yosemite National Park, California. It is a well-known rock formation in the park, named for its distinct shape. One side is a sheer face while the other three sides are smooth and round, making it appear like a dome cut in half. The granite crest rises more than above the valley floor. Geology The impression from the valley floor that this is a round dome that has lost its northwest half, is just an illusion. From Washburn Point, Half Dome can be seen as a thin ridge of rock, an arête, that is oriented northeast–southwest, with its southeast side almost as steep as its northwest side except for the very top. Although the trend of this ridge, as well as that of Tenaya Canyon, is probably controlled by master joints, 80 percent of the northwest "half" of the original dome may well still be there. Ascents As late as the 1870s, Half Dome was described as "perfectly inaccessible" by Josiah Whitney of the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Geological Survey
The California Geological Survey, previously known as the California Division of Mines and Geology, is the California state geologic agency. History Although it was not until 1880 that the California State Mining Bureau, predecessor to the California Geological Survey, was established, the "roots" of California's state geological survey date to an earlier time. As might be expected for a state that owed its existence to the gold rush of 1849, the California State Legislature recognized that geologists could provide valuable information. In 1851, one year after California was admitted to the United States, the Legislature named John B. Trask, a medical practitioner and active member of the California Academy of Sciences, as Honorary State Geologist. In 1853 the Legislature passed a joint resolution asking him for geological information about the state. He submitted a report ''On the Geology of the Sierra Nevada, or California Range''. About two months later, the Legislature creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
