Sierra Nevada (U
The Sierra Nevada () is a mountain range in the Western United States, between the Central Valley of California and the Great Basin. The vast majority of the range lies in the state of California, although the Carson Range spur lies primarily in Nevada. The Sierra Nevada is part of the American Cordillera, an almost continuous chain of mountain ranges that forms the western "backbone" of the Americas. The Sierra runs north-south and its width ranges from to across east–west. Notable features include General Sherman, the largest tree in the world by volume; Lake Tahoe, the largest alpine lake in North America; Mount Whitney at , the highest point in the contiguous United States; and Yosemite Valley sculpted by glaciers from one-hundred-million-year-old granite, containing high waterfalls. The Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite, Sequoia, and Kings Canyon National Parks; and Devils ...

Granite Dome
Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts. Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss. As granitic plutons cool kilometers below the Earth's surface, minerals in the rock crystallize under uniform confining pressure. Erosion brings the rock closer to Earth's surface and the pressure from above the rock decreases; as a result the rock fractures. These fractures are known as exfoliation joints, or sheet fractures, and form in onionlike patterns that are parallel to the land surface. These sheets of rock peel off the exposed surface and in certain conditions develop domical structures. Additional theories on the origin of granite domes involve scarp-retreat and tectonic uplift. Sheet fractures Sheet fractures are arcuate fractures defining slabs of rock that range from 0.5 to 10 meters thic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuolumne Meadows
Tuolumne Meadows () is a gentle, granitic dome, dome-studded, sub-alpine meadow area along the Tuolumne River in the eastern section of Yosemite National Park in the United States. Its approximate location is . Its approximate elevation is . The term ''Tuolumne Meadows'' is also often used to describe a large portion of the Yosemite National Park, Yosemite high country around the meadows, especially in context of rock climbing. Natural history The meadow vegetation is supported by shallow groundwater. The water comes from 1,000 mm (39 inches) of precipitation annually, predominantly in the form of snow. Water arises from snowmelt and hill-slope aquifers, and flows through the Tuolumne River, Budd Creek, Delaney Creek, and Unicorn Creek. In spring, as soon as the snow melts, it is not uncommon to see large areas of the meadows flooded and practically transformed into lakes. While the mountains of the Sierra near the meadows have had some permanent snowfields, in the summer they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Medlicott Dome
Medlicott Dome is a prominent granite dome in Yosemite high country. It is located on the southeast side of Tioga Road, between Mariolumne Dome and Dozier Dome, near Pywiack Dome, the Cathedral lakes, Drug Dome, East Cottage Dome, West Cottage Dome, North and South Whizz Domes, and Fairview Dome. It is popular with climbers, hikers and backpackers due to relative ease of access and ascent, as well as scenic views of Yosemite. Etymology The dome was named after Henry P. Medlicott. In 1882, with H. B. Carpenter, Medlicott surveyed the Great Sierra Wagon Road (now known as Tioga Road) through Yosemite. Henry P. Medlicott was a judge and US Deputy Mineral Surveyor from Lundy, California Lundy (formerly Mill Creek) is a defunct community in Mono County, California, United States, located on Mill Creek in Lundy Canyon near the west end of Lundy Lake. It is situated at an elevation of 7858 feet (2395 m). It was named after O.J. .... The original name of the peak, recorded in 18 ...

Pywiack Domes
Pywiack Dome is a prominent 600 foot granite dome in Yosemite National Park, located north-east of Tenaya Lake, west of Tuolumne Meadows and from the Tioga Road. It is quite near Harlequin Dome, and North and South Whizz Domes are north. Josiah Whitney the head of California Geological Survey wrote in 1863 about Pywiack Dome in ''Geology'': Climbing The west face of the formation is popular with rock climbers and has several multi-pitch slab climbs easily visible from the Tioga Road. Earliest was ''Dike Route'' a 6 pitch YDS 5.9R first climbed in August 1966 by Tom Gerughty, Roger Evje and Dave Meeks. Other popular climbs include Zee Tree (a 5 pitch YDS 5.7) and Aqua Knobby (a 4 pitch YDS 5.9) Etymology "Py-we-ack" in the native language means "glistening rocks", and the native people applied it to both the Tenaya Creek and Tenaya Lake, due to the abundance of glacial polish in the upper Tenaya basin. In 1932 the name "Pywiack" has applied to Pywiack Cascade. Pywi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California State Route 120
State Route 120 (SR 120) is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season. Route description SR 120 begins as a freeway intersecting Interstate 5 to extend Interstate 205 through Manteca. In east Manteca the freeway ends at SR 99 and becomes a highway which continues to head east through Escalon, Oakdale and other various small towns. East of Oakdale there are no highly populated area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yosemite Decimal System
The Yosemite Decimal System (YDS) is a three-part system used for rating the difficulty of walks, hikes, and climbs, primarily used by mountaineers in the United States and Canada. It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems, particularly those developed in Yosemite Valley, and quickly spread throughout North America. Description The class 5 portion of the class scale is primarily a rock climbing classification system, while classes 1–2 are used mainly in hiking and trail running. Class 3 describes easy and moderate climbing (i.e. scrambling), with varying amounts of exposure (length of a possible fall). Class 4 is an "in-between" rating that describes a very exposed scramble, corresponding roughly to the IFAS classification of PD+. Climbers, specifically those involved with technical class 5 climbing, often abbreviate "class 3" and "class 4" to "3rd" and "4th" respectively. Originally the system was ...

Bolt (climbing)
In rock climbing, a bolt is a permanent anchor fixed into a hole drilled in the rock as a form of protection. Most bolts are either self-anchoring expansion bolts or fixed in place with liquid resin. Description While bolts are commonplace in rock and gym climbing there is no universal vocabulary to describe them. Generally, a ''bolt hanger'' or a ''fixed hanger'' is a combination of a fixed bolt and a specialized stainless steel hanger designed to accept a carabiner, whereas in certain regions a ''bolt runner'' or a ''carrot'' describes a hangerless bolt (where the climber must provide their own hanger bracket and sometimes lock nut). A ''ring bolt'' has a loop on one end so it presents as a U-shape embedded in the wall. A climbing rope is then clipped into the carabiner. Generally quickdraws or slings are employed between bolt hangers and the rope to reduce drag when ascending, belaying and rappelling. Use Bolts are used in sport climbing as a backup to catch a fall, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
