Volcanic Ridge
Volcanic Ridge is an 11,486-foot-elevation (3,501 meter) ridge located in the Sierra Nevada mountain range in Madera County of northern California, United States. It is situated in the Ansel Adams Wilderness on land managed by Inyo National Forest. It is set in the Ritter Range, southeast of Mount Ritter, and approximately west of the community of Mammoth Lakes. The Minarets are one mile to the west and Devils Postpile National Monument is five miles to the southeast. Topographic relief is significant as the west aspect rises over above Iceberg Lake in approximately one-half mile. History The descriptive toponym was likely applied during an 1898–99 survey by the USGS, and has been officially adopted by the U.S. Board on Geographic Names. The first ascent of the summit was recorded August 13, 1933, by Craig Barbash and Howard Gates. The Minaret Mine was located on the south aspect of the ridge. Lead was mined there, but the remote location made mining unprofitable, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minarets (California)
The Minarets are a series of jagged peaks located in the Ritter Range, a sub-range of the Sierra Nevada in the state of California. They are easily viewed from Minaret Summit, which is accessible by auto. Collectively, they form an arête, and are a prominent feature in the Ansel Adams Wilderness which was known as the Minaret Wilderness until it was renamed in honor of Ansel Adams in 1984. The peaks were named in 1868 by the California Geographical Survey, which reported: "To the south of Mount Ritter are some grand pinnacles of granite, very lofty and apparently inaccessible, to which we gave the name of 'the Minarets.'" Seventeen of the Minarets have been given unofficial names, including Michael Minaret, Adams Minaret, Leonard Minaret, and Clyde Minaret. Clyde Minaret, named after Norman Clyde, is the tallest of the spires. The Southeast Face Route of Clyde Minaret is a technical rock climb featured in ''Fifty Classic Climbs of North America''. The area is notable for two ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steve Fossett
James Stephen Fossett (April 22, 1944 – September 3, 2007) was an American businessman and a record-setting aviator, sailor, and adventurer. He was the first person to fly solo nonstop around the world in a balloon and in a fixed-wing aircraft. He made his fortune in the financial services industry and held world records for five nonstop circumnavigations of the Earth: as a long-distance solo balloonist, as a sailor, and as a solo flight fixed-wing aircraft pilot. A fellow of the Royal Geographical Society and the Explorers Club, Fossett set more than one hundred records in five different sports, sixty of which still stood at the time of his death. He broke three of the seven absolute world records for fixed-wing aircraft recognized by the Fédération Aéronautique Internationale, all in his Virgin Atlantic GlobalFlyer. In 2002, he was awarded the Gold Medal of the Royal Aero Club of the UK, and was inducted into the National Aviation Hall of Fame in 2007. Fossett disappeare ...

Mountains Of The Ansel Adams Wilderness
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 ...

Minaret Lake
Minaret Lake is a lake in the Ritter Range, a subrange of the Sierra Nevada, in California. It is located in extreme northeastern Madera County, within the Ansel Adams Wilderness of the Inyo National Forest. Minaret Lake is notable for being on the Sierra High Route. It is near the fatal 2007 airplane crash site of Steve Fossett (Fossett's plane crashed north of the lake, near the Minaret Mine on Volcanic Ridge).

San Joaquin River
The San Joaquin River (; es, Río San Joaquín) is the longest river of Central California. The long river starts in the high Sierra Nevada, and flows through the rich agricultural region of the northern San Joaquin Valley before reaching Suisun Bay, San Francisco Bay, and the Pacific Ocean. An important source of irrigation water as well as a wildlife corridor, the San Joaquin is among the most heavily dammed and diverted of California's rivers. People have inhabited the San Joaquin Valley for more than 8,000 years, and it was long one of the major population centers of pre-Columbian California. Starting in the late 18th century, successive waves of explorers then settlers, mainly Spanish and American, emigrated to the San Joaquin basin. When Spain colonized the area, they sent soldiers from Mexico, who were usually of mixed native Mexican and Spanish birth, led by Spanish officers. Franciscan missionaries from Spain came with the expeditions to evangelize the natives by teac ... [...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] |
Snowfall
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...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 ...
