Johnson Peak
Johnson Peak is the highest mountain, in Tuolumne Meadows, Yosemite National Park. Johnson Peak is made of eroded granite. At 85 Year#SI_prefix_multipliers, Ma, the Johnson Granite Porphyry is the youngest granite rock in the Yosemite National Park, though the entire peak formed beneath the Earth's crust. It broached the surface much later, via subduction (geology), subduction. Despite it being a fairly easy hike, Johnson Peak climbed less frequently than its many neighbors.

Matthes Crest
Matthes Crest is an approximately mile-long fin of rock with two summits separated by a deep notch. It is a part of the Cathedral Range, which is a mountain range in the south-central portion of Yosemite National Park. The range is part of the Sierra Nevada (U.S.), Sierra Nevada. History and geology Matthes Crest is named for François E. Matthes, a cartographer and author who described the geology in the region where Matthes Crest lies. It was originally named Echo Ridge due to its proximity to the Echo Peaks. Matthes crest arose as a nunatak in the glacial field which covered Tuolumne during the last ice age. Climbing The first known ascent of Matthes Crest was by Jules Eichorn, Glen Dawson (mountaineer), Glen Dawson, and Walter Brem on June 16, 1931. Climbing Matthes Crest by traversing the ridge from south to north is a popular alpine climbing activity today.

Cathedral Peak (California)
Cathedral Peak is part of the Cathedral Range, a mountain range in the south-central portion of Yosemite National Park in eastern Mariposa County, California, Mariposa and Tuolumne County, California, Tuolumne Counties. The range is an offshoot of the Sierra Nevada (U.S.), Sierra Nevada. The peak which lends its name to the range derives its name from its cathedral-shaped peak, which was formed by glacier, glacial activity: the peak remained uneroded above the glaciers in the Pleistocene. Geography Cathedral Peak has a subsidiary summit to the west called Eichorn Pinnacle, for Jules Eichorn, who first ascended a Yosemite Decimal System, class 5.4 route to its summit on July 24, 1931, with Glen Dawson (mountaineer), Glen Dawson.

Johnson Granite Porphyry
Johnson Granite Porphyry is found in Tuolumne Meadows, Yosemite National Park. Johnson Granite Porphyry was named for Johnson Peak, the highest mountain in Tuolumne Meadows, Yosemite National Park. Its area is estimated at , the exposed area covering roughly .Glazner, Allen F, Stock, Greg M. (2010). ''Geology Underfoot in Yosemite''. Mountain Press, p. 53. . Johnson Granite Porphyry is part of the Tuolumne Batholith. Its boundaries are difficult to trace, and are irregular. It is both the youngest, and the most siliceous rock of Tuolumne Intrusive Suite. Geology The innermost, most felsic part of the Tuolumne Batholith is the Johnson Granite Porphyry. It is a highly irregular, elongated body. Completely surrounding it is the much larger body of Cathedral Peak granite. Field observations and magnetic fabrics suggest an extrusive event, that is, Johnson Granite Porphyry may record possible volcanism. This may relate to deformation along active shear zones.

Surveying
Surveying or land surveying is the technique, profession, art, and science of determining the land, terrestrial Plane (mathematics), two-dimensional or Three-dimensional space#In Euclidean geometry, three-dimensional positions of Point (geometry), points and the Euclidean distance, distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations, such as the designated positions of structural components for construction or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. A professional in land surveying is called a land surveyor. Surveyors work with elements of geodesy, geometry, trigonometry, regression analysis, physics, engineering, metrology, programming languages, and the law. They use equipment, such as total stations, robotic total stations, theodolites, Satellite navigation, GNSS receivers, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guide
A guide is a person who leads travelers, sportspeople, or tourists through unknown or unfamiliar locations. The term can also be applied to a person who leads others to more abstract goals such as knowledge or wisdom. Travel and recreation Explorers in the past venturing into territory unknown by their own people invariably hired guides. Military explorers Lewis and Clark were hired by the United States Congress to explore the Pacific Northwest. They in turn hired the better qualified Native American Sacagawea to help them. Wilfred Thesiger hired guides in the deserts that he ventured into, such as Kuri on his journey to the Tibesti Mountains in 1938. Tour guide Tour guides lead visitors through tourist attractions and give information about the attractions' natural and cultural significance. Often, they also act as interpreters for travelers who do not speak the local language. Automated systems like audio tours are sometimes substituted for human tour guides. Tour op ...

Teamster
A teamster in American English is a truck driver; a person who drives teams of draft animals; or a member of the International Brotherhood of Teamsters, a labor union. In some places, a teamster was called a carter, the name referring to the bullock cart. Originally the term ''teamster'' meant a person who drove a team, usually of oxen, horses, or mules, pulling a wagon, replacing the earlier ''teamer''. This term was common by the time of the Mexican–American War (1848) and the Indian Wars throughout the 19th and early 20th centuries on the American frontier. Another name for the occupation was ''bullwhacker'', related to driving oxen. A teamster might also drive pack animals, such as a muletrain, in which case he was also called a muleteer or muleskinner. Today this person may be called an outfitter or packer. In Australian English, a teamster was also called a bullocker or bullocky and was sometimes used to denote a carrier. From the Revolutionary War at le ...

Mount Lyell (California)
Mount Lyell is the highest point in Yosemite National Park, at . It is located at the southeast end of the Cathedral Range, northwest of Rodgers Peak. The peak as well as nearby Lyell Canyon is named after Charles Lyell, a well-known 19th century geologist. The peak had one of the last remaining glaciers in Yosemite, Lyell Glacier. The Lyell Glacier is currently considered to be a permanent ice field, not a living glacier. Mount Lyell divides the Tuolumne River watershed to the north, the Merced to the west, and the Rush Creek drainage in the Mono Lake Basin to the southeast. Climbing The most common approach to Mount Lyell is from Tuolumne Meadows on a highly traveled section of the John Muir Trail. The round trip is approximately and involves of elevation gain when starting from the Tuolumne Wilderness Office. The hike is easy from Tuolumne Meadows, following the Tuolumne River to the head of the Lyell Canyon, and becomes moderate as it approaches Donohue Pass. Before re ...
