Hawksbeak Peak
Hawksbeak Peak is a mountain summit with an elevation of located on the crest of the Sierra Nevada mountain range, in northern California, United States. The granitic summit is situated on the common boundary shared by Yosemite National Park with Hoover Wilderness, as well as the common border of Mono County and Tuolumne County. This remote peak is set at the head of Thompson Canyon, approximately eight miles west of Twin Lakes and 17 miles southwest of Bridgeport, the nearest town. Topographic relief is significant as the west aspect rises over in less than one-quarter mile. The West Face was first climbed in September 1989 by Alan Swanson and John Nye. This landform's toponym has been officially adopted by the U.S. Board on Geographic Names. Climate According to the Köppen climate classification system, Hawksbeak 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 appro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains Of Mono 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 (topography), 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 Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, 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 Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Tower Peak (California)
Tower Peak is a mountain in the Sierra Nevada of Mono and Tuolumne County, California. To the south of the summit is Yosemite National Park and to the north is the Hoover Wilderness. Mary Lake is to the west, Ehrnbeck Peak and Hawksbeak Peak to the east. To the south are Wells Peak and Craig Peak. The next higher mountain is Eagle Peak, about 8 mi east-northeast. Climate Tower 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 approach, they are forced upward by the peaks (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 cr ...), causing them to drop their moisture in the form of rain or snowfall onto the range.

Wells Peak
Wells Peak is a granitic mountain summit with an elevation of located in Yosemite National Park, in Tuolumne County, California, United States. The peak is situated between Stubblefield and Thompson canyons in the Sierra Nevada mountain range. Topographic relief is significant as the summit rises above Stubblefield Canyon in one mile. Precipitation runoff from this landform drains southwest to Hetch Hetchy via Rancheria Creek. History Wells Peak was named in the 1890s by R. B. Marshall of the USGS to honor Rush Spencer Wells (1874–1951), US Army officer. The US Army had jurisdiction over Yosemite National Park from 1891 to 1914, and each summer 150 cavalrymen traveled from the Presidio of San Francisco to patrol the park. This landform's toponym was officially adopted by the U.S. Board on Geographic Names in 1932. The first ascent of the summit was made July 27, 1945, by Arthur J. Reyman.

Hunewill Peak
Hunewill Peak is a mountain with a summit elevation of located in the Sierra Nevada mountain range, in Mono County of northern California, United States. The summit is set in Hoover Wilderness on land managed by Humboldt–Toiyabe National Forest. The peak is situated approximately four miles west of Twin Lakes, 1.3 mile southwest of Victoria Peak, and 2.4 miles southwest of line parent Eagle Peak. Precipitation runoff from this mountain drains into tributaries of Robinson and Buckeye Creeks, which are within the Walker River drainage basin. Topographic relief is significant as the summit rises over above Robinson Creek in approximately . History Hunewill Peak is the toponym officially adopted in 1962 by the U.S. Board on Geographic Names to remember Napoleon Bonaparte "N. B." Hunewill (1828–1908), a pioneer who operated the Eagle Creek Lumber Mill in this area in the 1860s and supplied timber to build the mining town of Bodie.

Geology Of The Yosemite Area
The exposed geology of the Yosemite area includes primarily granitic rocks with some older metamorphic rock. The first rocks were laid down in Precambrian times, when the area around Yosemite National Park was on the edge of a very young North American continent. The sediment that formed the area first settled in the waters of a shallow sea, and compressive forces from a subduction zone in the mid-Paleozoic fused the seabed rocks and sediments, appending them to the continent. Heat generated from the subduction created island arcs of volcanoes that were also thrust into the area of the park. In time, the igneous and sedimentary rocks of the area were later heavily metamorphosed. Most of the rock now exposed in the park is granitic, having been formed 210 to 80 million years ago as igneous diapirs 6 miles (10 km) below the surface. Over time, most of the overlying rock was uplifted along with the rest of the Sierra Nevada and was removed from the area by erosion. This exposed t ...

Rancheria Creek (Tuolumne County, California)
Rancheria Creek is a long stream in northern Yosemite National Park mostly in Tuolumne County, California and is a tributary of the Tuolumne River. Draining a large area of the Sierra Nevada, it is the largest tributary of the Tuolumne within Yosemite National Park. The stream is labeled as Kerrick Creek on some early maps. The creek begins at Peeler Lake at the Sierra Crest, in Mono County, and immediately crosses westward into Tuolumne County. It flows in a southerly direction through Kerrick Meadow and a series of high mountain valleys until reaching Kerrick Canyon, where it turns abruptly west. The Pacific Crest Trail parallels the creek through Kerrick Canyon. At the end of the canyon it receives a major tributary from Stubblefield Canyon and turns southwest, receiving Tilden Creek. Continuing southwest, it flows through rugged and complex granite formations, receives Breeze Creek, then turns west once more for its last few miles. It drops over Rancheria Falls before empty ...

West Walker River
The West Walker River is a tributary of the Walker River, approximately long,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 17, 2011 in eastern California and western Nevada in the United States. It drains part of the Sierra Nevada range along the California-Nevada border in the watershed of Walker Lake in the Great Basin. The river derives its name from Joseph R. Walker, a mountain man. It rises from snowmelt in the Sierras of northwestern Mono County, north of Yosemite National Park approximately south-southwest of Walker in the snowfields on the northeast faces of Tower Peak and Forsyth Peak on the Sierra crest in the Toiyabe National Forest. It flows north, along the west side of the Sweetwater Mountains, emerging into the Antelope Valley, a ranching region around Walker.

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] |
