Elephants Back
Elephants Back is a 9,585-foot-elevation (2,922 meter) mountain summit located in Alpine County, California, United States. Description This landmark of Hope Valley is set in the Mokelumne Wilderness of the Sierra Nevada mountain range. The summit is situated one mile south of Carson Pass and 1.4 mile (2.25 km) northeast of line parent Round Top. Elephants Back is a lava dome which was created in association with the now-inactive volcanic vent that is Round Top. Precipitation runoff from the peak's east slope drains to the West Fork Carson River via Red Lake Creek, whereas the west slope drains to Caples Lake via Woods Creek. Topographic relief is significant as the summit rises 1,600 feet (488 meters) above Forestdale Creek in less than one mile. The Pacific Crest Trail traverses the eastern and northern slopes of this peak, providing an approach from California State Route 88. History During his second exploratory expedition, John C. Frémont campe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Round Top (Alpine County, California)
Round Top is a mountain located on the Sierra crest in Alpine County, California, United States. Its summit is the highest point in Eldorado National Forest and the Mokelumne Wilderness. The mountain lies just south of Carson Pass. With of prominence, Round Top is the 16th most prominent mountain in the Sierra Nevada. Geology Round Top is the remnant of a volcano that formed in the Miocene epoch, which lasted from 23 million years ago to 5 million years ago. Most of the mountain's vertical height consists of an intrusive volcanic plug formed of basaltic andesite. This intrusive structure formed under the volcano's surface as subsurface magma gradually cooled and solidified. Approximately is exposed by the northern wall of Summit City canyon, which forms the south face of the mountain. A strong magnetic anomaly in the vicinity indicates that this plug further extends far below the canyon floor. The upper layers of the mountain are made up of extrusive rocks, which formed a ...

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] |

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] |

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 ...

Kit Carson
Christopher Houston Carson (December 24, 1809 – May 23, 1868) was an American frontiersman. He was a fur trapper, wilderness guide, Indian agent, and U.S. Army officer. He became a frontier legend in his own lifetime by biographies and news articles, and exaggerated versions of his exploits were the subject of dime novels. His understated nature belied confirmed reports of his fearlessness, combat skills, tenacity, and profound effect on the westward expansion of the United States. Although he was famous for much of his life, historians in later years have written that Kit Carson did not like, want, or even fully understand the fame that he experienced during his life. Carson left home in rural Missouri at 16 to become a mountain man and trapper in the West. In the 1830s, he accompanied Ewing Young on an expedition to Mexican California and joined fur-trapping expeditions into the Rocky Mountains. He lived among and married into the Arapaho and Cheyenne tribes. In the 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California State Route 88
State Route 88 (SR 88), also known as the Carson Pass Highway, is a state highway in the U.S. state of California. It travels in an east–west direction from Stockton in the San Joaquin Valley, crossing the Sierra Nevada at Carson Pass, and ending at the Nevada state line, whereupon it becomes Nevada State Route 88, eventually terminating at U.S. Route 395. Unlike other two-lane California highways through the mountains (Routes 4, 108 and 120), Route 88 stays open through winter, except during the worst snowstorms, making it the third major route through the mountains, after Interstate 80 and U.S. Route 50. In fact, Route 88 over the Carson Pass is designated as Alternate U.S. 50, such that it may be used during floods of the American River Canyon. Route description SR 88 begins just outside Stockton as Waterloo Road, heading northeast towards Waterloo. The highway turns north at Waterloo, and SR 88 continues north to an intersection with SR 12, where the latter runs co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Crest Trail
The Pacific Crest Trail (PCT), officially designated as the Pacific Crest National Scenic Trail, is a long-distance hiking and equestrian trail closely aligned with the highest portion of the Cascade and Sierra Nevada mountain ranges, which lie east of the U.S. Pacific coast. The trail's southern terminus is next to the Mexico–United States border, just south of Campo, California, and its northern terminus is on the Canada–US border, upon which it continues unofficially to the Windy Joe Trail within Manning Park in British Columbia; it passes through the states of California, Oregon, and Washington. The Pacific Crest Trail is long and ranges in elevation from roughly above sea level near the Bridge of the Gods on the Oregon–Washington border to at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks. Its midpoint is near Chester, California (near Mt. Lassen), where the Sierra and Cascade mountain ranges meet. It was d ...
