Mount Bolton Brown
Mount Bolton Brown is a 13,491-foot-elevation (4,112 meter) mountain summit located on the shared border of Fresno County and Inyo County in California, United States. Description The peak is set on the crest of the Sierra Nevada mountain range, just south of the Palisades area. It is also situated on the boundary shared by Kings Canyon National Park and John Muir Wilderness. Mount Bolton Brown ranks as the 64th-highest peak in California. Precipitation runoff from this mountain drains east to Tinemaha Reservoir via Tinemaha Creek; south into headwaters of South Fork Kings River; and northwest to Palisade Creek which is a tributary of the Middle Fork Kings River. Topographic relief is significant as the summit rises above Tinemaha Creek in 2.5 miles. Climbing The John Muir Trail, which passes below the western base of the peak, provides a climbing approach option. The first ascent of the summit was made August 14, 1922, by Chester Versteeg and Rudolph Berls by ascending t ... [...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 ...

South Fork Kings River
The South Fork Kings River is a tributary of the Kings River in the Sierra Nevada of Fresno County, California. The river forms part of Kings Canyon, the namesake of Kings Canyon National Park and one of the deepest canyons in North America with a maximum relief of from rim to river. Course The South Fork is the largest headwater of the Kings River. It originates at an elevation of at an unnamed lake in Kings Canyon National Park, south of Mather Pass and west of Split Mountain, in a high alpine basin known as Upper Basin. It flows south, and is paralleled for several miles by the combined Pacific Crest Trail/John Muir Trail. The trail and river separate at a point west of Taboose Pass, where the river turns to the southwest through a deep gorge between Cirque Crest to the northwest and Arrow Ridge to the southeast. To the east, the Muro Blanco cliffs rise more than half a mile (0.8 km) above the river. The river flows into Paradise Valley, where it flows in a south-sou ...

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] |
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] |
Sierra Club
The Sierra Club is an environmental organization with chapters in all 50 United States, Washington D.C., and Puerto Rico. The club was founded on May 28, 1892, in San Francisco, California, by Scottish-American preservationist John Muir, who became the first president as well as the longest-serving president, at approximately 20 years in this leadership position. The Sierra Club operates only in the United States and holds the legal status of 501(c)(4) nonprofit social welfare organization. Sierra Club Canada is a separate entity. Traditionally associated with the progressive movement, the club was one of the first large-scale environmental preservation organizations in the world, and currently engages in lobbying politicians to promote environmentalist policies. Recent focuses of the club include promoting sustainable energy and mitigating global warming, as well as opposition to the use of coal, hydropower and nuclear power. The club is known for its political endorsements, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peakbagging
Peak bagging or hill bagging is an activity in which hikers, climbers, and mountaineers attempt to reach a collection of summits, published in the form of a list. This activity has been popularized around the world, with lists such as 100 Peaks of Taiwan, four-thousand footers, ''100 Famous Japanese Mountains'', the Sacred Mountains of China, the Seven Summits, the Fourteeners of Colorado, and the eight-thousanders becoming the subject of mass public interest. There are numerous lists that a peakbagger may choose to follow. A list usually contains a set of peaks confined to a geographical area, with the peaks having some sort of subjective popularity or objective significance, such as being among the highest or most prominent of the area. Some maps and lists may be inaccurate, however, which has implications for climbers and peak-baggers who rely on publicly reported data. Although peak bagging is a fundamental part of the sport of mountaineering, the term is strongly associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Versteeg
Mount Versteeg is a mountain summit located on the crest of the Sierra Nevada mountain range in California. It is situated on the common border of Tulare County with Inyo County, as well as the shared boundary of Sequoia National Park and John Muir Wilderness. It is west-northwest of the community of Lone Pine, southeast of Mount Tyndall, southwest of Mount Williamson, and 0.68 mile northwest of Trojan Peak, the nearest higher neighbor. Mt. Versteeg ranks as the 66th highest peak in California. Topographic relief is significant as it rises approximately above Lake Helen of Troy in approximately 0.2 mile. Etymology The peak's name was officially adopted by the United States Board on Geographic Names in 1964 in memory of Chester Versteeg (1887–1963), lawyer, author, and prominent Sierra Club member who devoted much of his life to furthering interest in the Sierra Nevada. He is credited with 40 first ascents in the Sierra Nevada, such as Mount Tinemaha, Mount Goode, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
