Aperture Peak
Aperture Peak is a 13,265-foot-elevation (4,043 meter) mountain summit located in Inyo County, California, United States. Description Aperture Peak is set within the John Muir Wilderness, on land managed by Inyo National Forest. It is situated one-half mile east of the crest of the Sierra Nevada mountain range in the Palisades area, just outside the boundary of Kings Canyon National Park. It is approximately west of the community of Big Pine, one mile (1.6 km) east-northeast of Bishop Pass, north of line parent Mount Agassiz, and southeast of Picture Puzzle. Aperture Peak ranks as the 95th-highest summit in California, and the fourth-highest peak of the Inconsolable Range. Topographic relief is modest as the summit rises above the Big Pine Lakes in 1.5 mile. The west face of the peak features a large, white, diagonal dike, and a rock glacier lies below the east face. History The first ascent of the summit was made June 14, 1934, by David Brower and Hervey Voge. Thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Agassiz (California)
Mount Agassiz, at , is one of the 20 highest peaks of California. It is the northernmost and easiest to climb of the major Palisades summits. This peak is not to be confused with the peak by the same name in Desolation Wilderness, also in the California Sierra. Geography Agassiz is at the north end of the Palisades in the eastern Sierra Nevada, near Bishop Pass. It stands on the boundary between Kings Canyon National Park and Inyo National Forest, and Fresno and Inyo counties. History In 1879, Lilbourne Winchell named it Agassiz Needle for Harvard University professor of zoology and geology Louis Agassiz. Later, the USGS recognized it by its current name. The peak is named after Swiss-American scientist Louis Agassiz. The name Agassiz Needle was originally applied to another nearby peak in 1879, likely Mount Winchell, but at some point the name moved to the current peak. Climbing There are three major routes to Agassiz's summit. The easiest is the west slope, both for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Glacier
Rock glaciers are distinctive geomorphological landforms, consisting either of angular rock debris frozen in interstitial ice, former "true" glaciers overlain by a layer of talus, or something in-between. Rock glaciers are normally found at high latitudes and/or elevations, and may extend outward and downslope from talus cones, glaciers or terminal moraines of glaciers. There are two types of rock glaciers: periglacial glaciers (or talus-derived glaciers), and glacial rock glaciers, such as the Timpanogos Glacier in Utah, which are often found where glaciers once existed. Possible Martian rock glacier features have been identified by the Mars Orbiter spacecraft. A rock glacier, especially if its origin is unclear, can be considered as a discrete debris accumulation. Formation The two known factors that must be present in order to create rock glaciers are low ice velocity and permafrost. Most glacial rock glaciers are created by the recession of debris covered glaciers. Glacial ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 17, 2011 stream in Inyo County, California. It is the largest tributary of the Owens River. It has five hydroelectric plants owned by Southern California Edison, Bishop Creek #2–6. Bishop Creek #1 was never completed. Parts of the creek run through pipelines, or penstocks, to increase output at the power plants. Bishop Creek has three forks, North, Middle and South. All have their headwaters in the eastern Sierra Nevada, near the border with Fresno County. The forks all flow into lakes while still at high elevations. The North Fork flows into North Lake, the Middle Fork flows into Lake Sabrina. The North and Middle forks combine above and flow through the community of Aspendell and below it the combined creeks are dammed at Intake Two, a reservoir. The Sou ...

Big Pine Creek (California)
Big Pine Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map, accessed March 17, 2011 stream in Inyo County of eastern California, in the western United States. It flows from the eastern Sierra Nevada down to the Owens Valley, where it is a major tributary of the Owens River near Big Pine. Course The headwaters of Big Pine Creek are in the eastern slopes of the Sierra Nevada, near the border with Fresno County. The creek begins at the confluence of its North and South Forks, below the Palisades. From there, the creek flows east-northeast, passing Crater Mountain of the Big Pine volcanic field and intersecting Big Pine Canal before joining the Owens River near the town of Big Pine. The total average runoff from the watershed is , mostly from Big Pine Creek itself. Uses Despite its name, Big Pine Canal does not divert water from Big Pine Creek, it comes from the Owens River upstream. The canal provides water to the Big Pi ...

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 ...

Alpine Climate
Alpine climate is the typical weather (climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
