Parker Peak (California)
Parker Peak is a mountain summit located in the Sierra Nevada mountain range, in Mono County of northern California, United States. It is situated in the Ansel Adams Wilderness, on land managed by Inyo National Forest. It is approximately northwest of the community of June Lake, east of Yosemite National Park's eastern boundary, and east of Koip Peak, the nearest higher neighbor. The mountain is visible from the June Lake Loop, and from the nearby June Mountain ski area. Topographic relief is significant as it rises over above Grant Lake in four miles. The peak's name is derived from Parker Creek, which in turn was named after an early settler of Mono County. This geographical feature's name has been officially adopted by the U.S. Board on Geographic Names. The first ascent of the summit was made in 1914 by Norman Clyde. Climate According to the Köppen climate classification system, Parker Peak has an alpine climate. Most weather fronts originate in the Pacific Ocean, and ...

First Ascent
In mountaineering, a first ascent (abbreviated to FA in guide books) is the first successful, documented attainment of the top of a mountain or the first to follow a particular climbing route. First mountain ascents are notable because they entail genuine exploration, with greater risks, challenges and recognition than climbing a route pioneered by others. The person who performs the first ascent is called the first ascensionist. In free climbing, a first ascent (or first free ascent, abbreviated FFA) of a climbing route is the first successful, documented climb of a route without using equipment such as anchors or ropes for aiding progression or resting. History The details of the first ascents of even many prominent mountains are scanty or unknown; sometimes the only evidence of prior summiting is a cairn, artifacts, or inscriptions at the top. Today, first ascents are generally carefully recorded and usually mentioned in guidebooks. The term is also used when referrin ...

Mountains Of Mono 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 ...

Geology Of The Yosemite Area
The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock. The first rocks were laid down in Precambrian times, when the area around Yosemite National Park was on the edge of a very young North American continent. The sediment that formed the area first settled in the waters of a shallow sea, and compressive forces from a subduction zone in the mid-Paleozoic fused the seabed rocks and sediments, appending them to the continent. Heat generated from the subduction created island arcs of volcanoes that were also thrust into the area of the park. In time, the igneous and sedimentary rocks of the area were later heavily metamorphosed. Most of the rock now exposed in the park is granitic, having been formed 210 to 80 million years ago as igneous diapirs 6 miles (10 km) below the surface. Over time, most of the overlying rock was uplifted along with the rest of the Sierra Nevada and was removed from the area by erosion. This expos ...

Mount Gibbs
Mount Gibbs is located in the Sierra Nevada of the U.S. state of California, south of Mount Dana. The mountain was named in honor of Oliver Gibbs, a professor at Harvard University and friend of Josiah Whitney. The summit marks the boundary between Yosemite National Park and the Ansel Adams Wilderness, and Mount Gibbs is the sixth-highest mountain, of Yosemite. The peak is accessible either from the west, starting at Tioga Pass Road, or from the east, via Bloody Canyon from the trailhead at Walker Lake. Overnight camping is not permitted on the western side of the mountain, which is part of the protected watershed of Dana Meadows and Tioga Pass. In the summer the mountain has only patchy snow, on the northern slope. The easiest ascent is via the ridge extending west from the peak; there is a steep section of loose, unstable rock, leading to the gentle ridge that forms the top of the mountain. Although the top is above the tree line, there is some sparse plant life, includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Lewis (California)
Mount Lewis is a 12,350-foot-elevation (3,764 meter) mountain summit located along the crest of the Sierra Nevada mountain range, in Mono County of northern California, United States. It is situated in the Ansel Adams Wilderness, on land managed by Inyo National Forest. The summit lies less than one mile outside of Yosemite National Park's eastern boundary, and some of the lower western slope lies within the park. The mountain rises southeast of Mono Pass, northeast of Parker Pass, and two miles north of Parker Peak, which is the nearest higher neighbor. Topographic relief is significant as it rises over above Grant Lake in four miles which makes the mountain visible from Highway 395. Etymology The mountain is named in memory of Washington Bartlett "Dusty" Lewis (1884–1930), Superintendent of Yosemite National Park for 11 years from 1917 through 1928. He played a leading part in the development of the park and in standardizing uniforms for National Park Service employees. Th ...

Mount Wood (California)
Mount Wood is a 12,657-foot-elevation (3,858 meter) mountain summit located just east of the crest of the Sierra Nevada mountain range, in Mono County of northern California, United States. It is situated in the Ansel Adams Wilderness, on land managed by Inyo National Forest. It is approximately northwest of the community of June Lake, two miles outside of Yosemite National Park's eastern boundary, and one mile east-southeast of line parent Parker Peak. Topographic relief is significant as the summit rises over above Grant Lake in three miles. The mountain is visible from the June Lake Loop. History This geographical feature was named in 1894 by Lieutenant Nathaniel Fish McClure who prepared a map of Yosemite Park for use by Army troops. The toponym honors Captain Abram Epperson Wood, 4th Cavalry US Army, the first acting military superintendent of Yosemite National Park from 1891 to 1893, shortly before he died in 1894. The US Army had jurisdiction over Yosemite Nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rush Creek (Mono County, California)
Rush Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 17, 2011 creek in California on the eastern slope of the Sierra Nevada, running east and then northeast to Mono Lake. Rush Creek is the largest stream in the Mono Basin, carrying 41% of the total runoff. It was extensively diverted by the Los Angeles Aqueduct system in the twentieth century until California Trout, Inc., the National Audubon Society, and the Mono Lake Committee sued Los Angeles Department of Water and Power (LADWP) for continuous low flows in Rush Creek to maintain trout populations in good condition, which was ordered by the court in 1985. History On A. W. Schmidt's plat of 1857 it was called Lake Creek, possibly because it was the major stream flowing into Mono Lake. The Rush Creek place name appeared on the Hoffmann and Gardiner map of 1863-1867 and is one of the older place names on the eastern slope of the Sierra, although the orig ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orographic Lift
Orographic lift occurs when an air mass is forced from a low elevation to a higher elevation as it moves over rising terrain. As the air mass gains altitude it quickly cools down adiabatically, which can raise the relative humidity to 100% and create clouds and, under the right conditions, precipitation. Orographic lifting can have a number of effects, including precipitation, rain shadowing, leeward winds, and associated clouds. Precipitation Precipitation induced by orographic lift occurs in many places throughout the world. Examples include: * The Mogollon Rim in central Arizona * The western slope of the Sierra Nevada range in California * The mountains near Baja California North – specifically La Bocana to Laguna Hanson. * The windward slopes of Khasi and Jayantia Hills (see Mawsynram) in the state of Meghalaya in India. * The Western Highlands of Yemen, which receive by far the most rain in Arabia. * The Western Ghats that run along India's western coast. * The Gr ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Weather Front
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients are known as dry lines can trigger severe weather. Some fronts produce no precipitation and little cloudiness, although there is invariably always a wind shift. Cold fronts generally move from west to east, whereas warm fronts move poleward, although any direction is possible. Occluded fronts are a hybrid merge of the two, and stationary fronts are stalled in their motion. Cold fronts and cold occlusions move faster than warm fronts and warm occlusions because the dense air behind them can lift as we ...
