Matthes Crest
Matthes Crest is an approximately mile-long fin of rock with two summits separated by a deep notch. It is a part of the Cathedral Range, which is a mountain range in the south-central portion of Yosemite National Park. The range is part of the Sierra Nevada. History and geology Matthes crest is named for François E. Matthes, a cartographer and author who described the geology in the region where Matthes Crest lies. It was originally named Echo Ridge due to its proximity to the Echo Peaks. Matthes crest arose as a nunatak in the glacial field which covered Tuolumne during the last ice age. Climbing The first known ascent of Matthes Crest was by Jules Eichorn, Glen Dawson, and Walter Brem on June 16, 1931. Climbing Matthes Crest by traversing the ridge from south to north is a popular alpine climbing activity today.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Mariposa 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 ...

Geology Of Yosemite National Park
Geology () is a branch of natural science concerned with Earth and other Astronomical object, astronomical objects, the features or rock (geology), rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth science, 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 dating, relative and Geochronology, 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 Eart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elizabeth Lake (Yosemite National Park)
Elizabeth Lake is a lake, in the area of Tuolumne Meadows, in Yosemite National Park, California. It was named for a geologist's niece, one Elizabeth Crow Simmons. The lake is at the base of Unicorn Peak, and is also near Johnson Peak. The lake is in Tuolumne County, California. The hike To hike to Elizabeth Lake is , of perhaps two the three hours. One gains perhaps . As with all sights in Tuolumne, hiking the trail depends on season, usually May until October. For the hike, bug spray and sun tan lotion should be used.

Cockscomb (Tuolumne Meadows)
Cockscomb is a mountain, in the area of Tuolumne Meadows, Yosemite National Park, California. On Cockscomb's particulars Cockscomb is aptly named, notably when viewed from the northwest. It is located in the Yosemite Wilderness, and is often forgotten, due to its proximity to Cathedral Peak, Matthes Crest, and Echo Peaks, but is deserves to be climbed. The proximity of Cockscomb Cockscomb is near Echo Peaks, Unicorn Peak, Cathedral Peak, Matthes Crest, Budd Lake, also Elizabeth Lake. Rock climbing on Cockscomb None of Cockscomb's routes walk-ups, the easiest a Class 4. Cockscomb has two summits, a west and an east, separated by about , with a sharp notch between. The west summit is a small perch, which can barely hold two people, while the east summit is a knife-edge, a dangerous perch. Their altitudes are within a few inches of each other, so saying which is higher is problematic. The west summit appears to be climbed more often, while the east summit is more diffic ...

Cathedral Peak (California)
Cathedral Peak is part of the Cathedral Range, a mountain range in the south-central portion of Yosemite National Park in eastern Mariposa and Tuolumne Counties. The range is an offshoot of the Sierra Nevada. The peak which lends its name to the range derives its name from its cathedral-shaped peak, which was formed by glacial activity: the peak remained uneroded above the glaciers in the Pleistocene. Geography Cathedral Peak has a subsidiary summit to the west called Eichorn Pinnacle, for Jules Eichorn, who first ascended a class 5.4 route to its summit on July 24, 1931, with Glen Dawson. In 1869, John Muir wrote in ''My first summer in the Sierra'': Geology The Cathedral Peak Granodiorite of Cathedral Peak is an intrusion into an area of older intrusive (or plutonic) and metamorphic rock in the Sierra Nevada Batholith. It is part of a grouping of intrusions called the Tuolumne Intrusive Suite. Cathedral Peak is the youngest of the rock formations in the Suite ...

Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Catherine ...

Ice Age
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called '' interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for th ...
