Mount Senger
Mount Senger is a 12,286-foot-elevation (3,745 meter) mountain summit located west of the crest of the Sierra Nevada mountain range in Fresno County of northern California, United States. It is set within the John Muir Wilderness, on land managed by Sierra National Forest. It is situated southeast of Mount Hooper, southwest of Gemini, and south-southwest of Seven Gables. Senger ranks as the 348th-highest summit in California. Topographic relief is significant as the summit rises over above the South Fork San Joaquin River in approximately three miles. The John Muir Trail traverses the south and west slopes of the mountain, providing an approach option. History The mountain was named in 1894 by Theodore Solomons to honor Joachim Henry Senger (1848–1926), philologist and professor at the University of California, Berkeley, who was one of the four founders of the Sierra Club in 1892. Senger contacted John Muir with the idea of forming a local 'alpine club' for mountain lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gemini (California Mountain)
Gemini is a twin-peaked mountain summit located west of the crest of 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. It is set west-southwest of Merriam Peak, northeast of Mount Senger, and southeast of Seven Gables, the nearest higher neighbor. Topographic relief is significant as it rises over above Piute Canyon in approximately three miles. Gemini ranks as the 176th-highest summit in California. History The first ascent of the summit was made July 30, 1953, by Jim Koontz and Rosemarie Lenel. The mountain's name was suggested by Chester Versteeg, a prominent Sierra Club mountaineer from Los Angeles.Erwin G. Gudde, ''California Place Names'', University of California Press, 1969, , page 142. The peak's name was officially adopted in 1954 by the U.S. Board on Geographic Names and promulgated in 1957. Today this peak draws climbing interest becau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 Gr ...

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 we ...

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 t ... [...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'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peak Bagging
Peak bagging or hill bagging is an activity in which Hiking, hikers, climbing, climbers, and Mountaineering, 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 topographical prominence, 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 ...

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 ...

Warren Olney
Warren Olney, Sr. (March 11, 1841 – June 2, 1921) was an American lawyer, conservationist, and politician, in California. He was a founding member, alongside John Muir and the young botany professor, Willis Linn Jepson of the University of California at Berkeley, of the Sierra Club. From 1903 to 1905 he served as the 34th Mayor of Oakland, California. Early life Olney was born near the Fox River in frontier Iowa and was raised in abject poverty and with little formal schooling. His family moved often and his education up to the age of 10 consisted of brief stints in log or early frame school houses and from his father who had only briefly attended school himself. Typical of the times, his mother was uneducated. She finally taught herself to read and write so as to communicate with her son during his military service during the Civil war. From the age of 10 through 17 no record has been found to verify whatever education he received. Where and however he got it, he lear ...

John Muir
John Muir ( ; April 21, 1838December 24, 1914), also known as "John of the Mountains" and "Father of the National Parks", was an influential Scottish-American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States of America. His letters, essays, and books describing his adventures in nature, especially in the Sierra Nevada, have been read by millions. His activism helped to preserve the Yosemite Valley and Sequoia National Park, and his example has served as an inspiration for the preservation of many other wilderness areas. The Sierra Club, which he co-founded, is a prominent American conservation organization. In his later life, Muir devoted most of his time to the preservation of the Western forests. As part of the campaign to make Yosemite a national park, Muir published two landmark articles on wilderness preservation in '' The Century Magazine'', "The Treasures o ...
