Mount Agassiz (California)
Mount Agassiz, at , is one of the 20 highest peaks of California. It is the northernmost and easiest to climb of the major Palisades summits. This peak is not to be confused with the peak by the same name in Desolation Wilderness, also in the California Sierra. Geography Agassiz is at the north end of the Palisades in the eastern Sierra Nevada, near Bishop Pass. It stands on the boundary between Kings Canyon National Park and Inyo National Forest, and Fresno and Inyo counties. History In 1879, Lilbourne Winchell named it Agassiz Needle for Harvard University professor of zoology and geology Louis Agassiz. Later, the USGS recognized it by its current name. The peak is named after Swiss-American scientist Louis Agassiz. The name Agassiz Needle was originally applied to another nearby peak in 1879, likely Mount Winchell, but at some point the name moved to the current peak. Climbing There are three major routes to Agassiz's summit. The easiest is the west slope, both for i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Palisade
North Palisade is the third-highest mountain in the Sierra Nevada (U.S.), Sierra Nevada range of California, and one of the state's small number of peaks over 14,000 feet, known as fourteeners. It is the highest peak of the Palisades (California Sierra), Palisades group of peaks in the central part of the Sierra range. It sports a small glacier (the Palisade Glaciers, Palisade Glacier) and several highly prized rock climbing routes on its northeast side. History North Palisade has a collection of names from the 19th century. The Wheeler Survey referred to it as Northwest Palisade in 1878. The following year, Lilbourne A. Winchell called it Dusy's Peak after local rancher Frank Dusy. In 1895, Bolton Brown advocated yet another name, after David Starr Jordan. In 2009, U.S. Senator Dianne Feinstein, supported by U.S. Senator Barbara Boxer, introduced legislation to rename the peak as "Brower Palisade", in honor of environmentalist David Brower. There was significant opposition to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lilbourne Winchell
Lilbourne is a village and civil parish in West Northamptonshire in England. It is close to the M1 motorway which runs east of the village, and the A5 road, west of the village which marks the boundary with Warwickshire, slightly to the north is the River Avon which marks the boundary with Leicestershire (the three counties meeting at Dow Bridge). At the time of the 2001 census, the parish's population was 254 people, increasing to 273 at the 2011 Census, and further to 305 at the 2021 census. History The villages name means 'Lilla's stream'. Alternatively, the first element might be a stream-name, Lille. Just outside Lilbourne is the River Avon and the remains of a Norman motte-and-bailey castle. To the west of the castle is the local church, All Saints, which is Grade I listed building dating from the 12th century. A, smaller, motte and bailey castle lies 0.9 km to the north west of the village, at Lilbourne Gorse. No. 73 Squadron RAF was stationed at nearby RAF Lil ...

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 ...

Mountain Peaks Of California
This article comprises three sortable tables of major mountain peaksThis article defines a significant summit as a summit with at least of topographic prominence, and a major summit as a summit with at least of topographic prominence. All summits in this article have at least 500 meters of topographic prominence. An ultra-prominent summit is a summit with at least of topographic prominence. of the U.S. State of California. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level.All elevations in this article include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88).

Arête
An arête ( ) is a narrow ridge of rock which separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in ... events and the erosion of exposed, unstable rock. The word ''arête'' () is actually French for "edge" or "ridge"; similar features in the Alps are often described with the German language, German equivalent term ''Grat''. Where three or more cirques meet, a pyramidal peak is created. Cleaver A ''cleaver' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Couloir
A ''couloir'' (, "passage" or "corridor") is a narrow gully with a steep gradient in a mountainous terrain.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, p. 121. . Geology A couloir may be a seam, scar, or fissure, or vertical crevasse in an otherwise solid mountain mass. Though often hemmed in by sheer cliff walls, couloirs may also be less well-defined, and often simply a line of broken talus or scree ascending the mountainside and bordered by trees or other natural features. Couloirs are especially significant in winter months when they may be filled in with snow or ice, and become much more noticeable than in warmer months when most of the snow and ice may recede. These physical features make the use of couloirs popular for both mountaineering and extreme skiing Extreme skiing is performed on long, steep (typically from 45 to 60+ degrees, or grades of 100 to 170 percent) slopes in mountainous terrain. The French coined the term 'Le Ski Ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Winchell
Mount Winchell, a thirteener, is among the thirty highest peaks of California. It is in the Palisades region of the Sierra Nevada, on the Sierra Crest between Mount Agassiz and Thunderbolt Peak. Geography The Inyo-Kern County line follows Winchell's northwest-southeast ridges. Hydrologically, this same boundary divides the Big Pine Creek drainage from Dusy Basin, part of the Kings River's headwaters. Its west slopes fall within Kings Canyon National Park, while its east slopes are in the John Muir Wilderness of the Inyo National Forest. History Two mountain peaks in the vicinity were christened Mount Winchell during the 1870s, but neither of them were present day Mount Winchell. The United States Geological Survey applied the name to the present peak. The name's original application was made by Elisha Winchell for his cousin, Alexander Witchell, who was a founding member of the Geological Society of America. The first recorded climb of Mount Winchell was by Harvey C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...
