Gaylor Peak
Gaylor Peak is an 11,004-foot-elevation (3,354 meter) mountain summit located on the crest of the Sierra Nevada mountain range in northern California, United States. The peak is situated on the common boundary shared by Yosemite National Park with Inyo National Forest, as well as the border shared by Mono County with Tuolumne County. It rises immediately above the park's Tioga Pass entrance station and Tioga Lake. Topographic relief is significant as the summit rises approximately 1,400 feet (427 meters) above the lake in one-half mile (1 km). The peak is a popular hiking destination on summer weekends due to easy access via the two-mile Gaylor Lakes Trail from State Route 120 which traverses the east base of the peak. History This mountain's toponym was officially adopted by the United States Board on Geographic Names to honor Andrew Jack Gaylor (1846–1921), one of Yosemite's first park rangers. He died of a heart attack on April 19, 1921, while on pat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False White Mountain
False White Mountain is a mountain, in the northern part of Yosemite National Park. It is the 24th highest mountain, in Yosemite National Park. False White Mountain can be climbed, as a day hike, from Tioga Pass. False White Mountain is near Mount Conness, Tioga Peak, Mount Dana, and Lembert Dome, thus is in the Tuolumne Meadows area. Of importance, False White Mountain has been often confused with White Mountain, thus the "false" reference. There have been proposals, to re-name False White Mountain, as ''Peak 12,002'', ''Sharsmith Peak'', ''False White'', and ''False White Mountain Peak''. Climate False White Mountain is located in an alpine climate zone. Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains. As fronts approach, they are forced upward by the peaks (orographic lift), causing moisture in the form of rain or snowfall to drop onto the range.

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kuna Crest
Kuna Crest is a mountain range near Tuolumne Meadows, in Yosemite National Park, California. Name The word ''Kuna'' probably derives from a Shoshonean language, Shoshonean word meaning "fire," which appears in the Mono language (California), Mono dialect of the area, with a meaning of ''firewood''. On the summit of near-by Kuna Peak (Yosemite), Kuna Peak, there are many jagged pieces of rock which resemble fire themselves; see Kuna Crest Granodiorite. Geography and geology The Crest lies between two U-shaped glacial valleys: Lyell Canyon and the canyon of the Parker Pass Creek. Mammoth Peak (Yosemite National Park), Mammoth Peak lies at the northern end of the Kuna Crest. A number of lakes lie in cirques cut into the eastern edge of the Crest, including Kuna Lake, Bingaman Lake, Spillway Lake, and Helen Lake. The Crest consists of Kuna Crest Granodiorite, which is the oldest granitic rock of the Tuolumne Intrusive Suite. It is rich in biotite and hornblende. Rock climbing Cli ...

Mount Dana
Mount Dana is a mountain in the U.S. state of California. Its summit marks the eastern boundary of Yosemite National Park and the western boundary of the Ansel Adams Wilderness. At an elevation of , it is the second highest mountain in Yosemite (after Mount Lyell (California), Mount Lyell), and the northernmost summit in the Sierra Nevada which is over in elevation. Mount Dana is the highest peak in Yosemite that is a simple hike to the summit. The mountain is named in honor of James Dwight Dana, who was a professor of natural history and geology at Yale University, Yale. Mount Dana is composed of batholith, prebatholithic rock that is mostly reddish metamorphic rock, which was composed by metavolcanics of surfacing magma from the Mesozoic Era. Mount Dana's northern face includes a small, receding glacier known as the Dana Glacier (California), Dana Glacier. The Dana Meadows (California), Dana Meadows lie at the foot of the mountain.

Mono Lake
Mono Lake ( ) is a saline soda lake in Mono County, California, formed at least 760,000 years ago as a terminal lake in an endorheic basin. The lack of an outlet causes high levels of salts to accumulate in the lake which make its water alkaline. The desert lake has an unusually productive ecosystem based on brine shrimp, which thrive in its waters, and provides critical habitat for two million annual migratory birds that feed on the shrimp and alkali flies ('' Ephydra hians''). Historically, the native Kutzadika'a people ate the alkali flies' pupae, which live in the shallow waters around the edge of the lake. When the city of Los Angeles diverted water from the freshwater streams flowing into the lake, it lowered the lake level, which imperiled the migratory birds. The Mono Lake Committee formed in response and won a legal battle that forced Los Angeles to partially replenish the lake level. Geology Mono Lake occupies part of the Mono Basin, an endorheic basin that has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lee Vining Creek
Lee Vining Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 17, 2011 stream in Mono County, California, flowing into the endorheic basin of Mono Lake. It is the second largest stream flowing into the lake, after Rush Creek. Geography The stream rises near Tioga Pass in the Eastern Sierra Nevada, more than above sea level, in the Hoover Wilderness of the Inyo National Forest just outside the eastern boundary of Yosemite National Park. The headwaters of the creek consist of many high-altitude lakes, Saddlebag Lake being the largest, as well as permanent snowfields and the Conness Glacier. It flows southeast to Ellery Lake, a natural lake enlarged by a dam, where it turns east and drops over Ellery Lake Falls into the deep Lee Vining Canyon. From there, it flows eastwards out of the mountains past the small town of Lee Vining. The creek terminates at a small sandy delta on the western shore of Mono Lake. ...

Tuolumne River
The Tuolumne River ( Yokutsan: ''Tawalimnu'') flows for through Central California, from the high Sierra Nevada to join the San Joaquin River in the Central Valley. Originating at over above sea level in Yosemite National Park, the Tuolumne drains a rugged watershed of , carving a series of canyons through the western slope of the Sierra. While the upper Tuolumne is a fast-flowing mountain stream, the lower river crosses a broad, fertile and extensively cultivated alluvial plain. Like most other central California rivers, the Tuolumne is dammed multiple times for irrigation and the generation of hydroelectricity. Humans have inhabited the Tuolumne River area for up to 10,000 years. Prior to the arrival of Europeans, the river canyon provided an important summer hunting ground and a trade route between Native Americans in the Central Valley to the west and the Great Basin to the east. First named in 1806 by a Spanish explorer after a nearby indigenous village, the Tuolumne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Grea ...

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 well as push ...
