Silver Peak (Fresno County, California)
Silver Peak is an 11,878-foot-elevation (3,620 meter) mountain summit located in the Sierra Nevada mountain range in Fresno County, California, United States. It is set in the John Muir Wilderness, on land managed by Sierra National Forest. Silver Peak ranks as the 455th-highest summit in California, and topographic relief is significant as the east aspect rises nearly above Beetlebug Lake in approximately one mile. It is north of Lake Thomas A Edison, and approximately south of the community of Mammoth Lakes. The peak is situated on Silver Divide, two miles northwest of Graveyard Peak. The first ascent of the summit was made prior to 1937 by an unknown party. Inclusion on the Sierra Peaks Section peakbagging list generates climbing interest. Climate According to the Köppen climate classification system, Silver Peak 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sierra Peaks Section
The Sierra Peaks Section (SPS) is a mountaineering society within the Angeles Chapter of the Sierra Club that serves to provide mountaineering activities for Sierra Club members in the Sierra Nevada, and to honor mountaineers who have summited Sierra Nevada peaks. History The Sierra Peaks Section was established in 1955. The Section maintains historic summit registers at Bancroft Library on the University of California, Berkeley campus. Membership To become a member of the SPS, one must be a Sierra Club member and have climbed at least six peaks on the SPS List; it is not necessary that the peaks be Emblem peaks. For verification purposes, two of those ascents must be done on an official SPS trip. Especially accomplished members are award with ''emblems'', with the following grades (from highest to lowest): * Third List Completion * Second List Completion * First List Completion * Master Emblem * Senior Emblem * Emblem Upon receiving one of the normal emblems, members may be re ...

Silver Peak, Snowy
Silver is a chemical element with the symbol Ag (from the Latin ', derived from the Proto-Indo-European ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in curre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Fresno 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 ...

Mount Izaak Walton
Mount Izaak Walton is a 12,077-foot-elevation (3,681 meter) mountain summit located in the Sierra Nevada mountain range in Fresno County of northern California, United States. It is situated in the John Muir Wilderness, on land managed by Sierra National Forest. Mount Izaak Walton ranks as the 404th-highest summit in California. Topographic relief is significant as the northwest aspect rises above Izaak Walton Lake in approximately one mile. It is six miles northeast of Lake Thomas A Edison, and approximately south-southeast of the community of Mammoth Lakes. The peak is set on Silver Divide, so precipitation runoff from the north side of this mountain drains into Fish Creek which is a tributary of the San Joaquin River, and from the south slope to Mono Creek, also a tributary of the San Joaquin. History This mountain's toponym was proposed in 1919 by Francis P. Farquhar and officially adopted in 1926 by the U.S. Board on Geographic Names to honor Izaak Walton (1593–168 ...

Theodore Solomons
Theodore Seixas Solomons (1870–1947) was an explorer and early member of the Sierra Club. From 1892 to 1897 he explored and named the Mount Goddard, Evolution Valley and Evolution Basin region in what is now northern Kings Canyon National Park in eastern California. He was instrumental in envisioning, exploring, and establishing the route of what became the John Muir Trail from Yosemite Valley along the crest of the Sierra Nevada to Mount Whitney Biography Early life and ancestors He was born in San Francisco, California on July 20, 1870, the second son and the fifth of seven childrenSelina (b. 1862) became a writer and advocate for woman suffrage; Lucius Levy (b. 1863) became a lawyer and public speaker; Gertrude Marks (b. 1866) died at a young age; Adele Rosa (b. 1868) became a doctor; Leon Mendes (b. 1873) became a scholar; Frank Benjamin (b. 1875) died as an infant. of Hannah Marks, an influential San Francisco educator and civic worker and Gershom Mendes Seixas Solomon ...

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 ...
