Cathedral Group
The Cathedral Group is the group of the tallest mountains of the Teton Range, all of which are located in Grand Teton National Park in the U.S. state of Wyoming. The Cathedral Group are classic alpine peaks, with pyramidal shapes caused by glacial motion. The highest peak in the group is Grand Teton, which rises more than above Jackson Hole valley, and is the second tallest mountain in Wyoming, after Gannett Peak. The Cathedral Group is separated by other tall peaks of the range by the Cascade Canyon to the north and Avalanche Canyon to the south. Half the remaining dozen glaciers in the Teton Range are located in this cluster of high peaks, including the Teton Glacier which is the largest one in the range. Other glaciers such as the Middle Teton Glacier, Teepe Glacier, and Schoolroom Glacier are also located here. The Cathedral Group has several high cirques, arêtes as well as hanging and U-shaped valleys which are all the work of glacial activity. At the base of the Cathed ...

Cirque (landform)
A (; from the Latin word ') is an amphitheatre-like valley formed by glacial erosion. Alternative names for this landform are corrie (from Scottish Gaelic , meaning a pot or cauldron) and (; ). A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides. The floor of the cirque ends up bowl-shaped, as it is the complex convergence zone of combining ice flows from multiple directions and their accompanying rock burdens. Hence, it experiences somewhat greater erosion forces and is most often overdeepened below the level of the cirque's low-side outlet (stage) and its down-slope (backstage) valley. If the cirque is subject to seasonal melting, the floor of the cirque most often forms a tarn (small lake) behind a dam, which marks the down ...

South Teton
South Teton () is the fifth-highest peak in the Teton Range, Grand Teton National Park, in the U.S. state of Wyoming. The peak is south of Middle Teton and just west of Cloudveil Dome and is part of the Cathedral Group of high Teton peaks. The Teton Range is the youngest mountain chain in the Rocky Mountains, and began their uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved South Teton and the other peaks of the range into their current shapes. Climbing South Teton was first climbed on August 29, 1923 by Albert R. Ellingwood and Eleanor Davis. Ellingwood made the first ascent of Middle Teton the same day. Davis was the first woman to ascend Grand Teton. The easiest climbing route is via Garnet Canyon to an altitude of . From there a trail leads southwest towards a pass between South and Middle Teton. Most ascents of the summit are made from this pass. A number of more difficult ascents are also done by experienced climbers, with diffic ...

Middle Teton
Middle Teton () is the third-highest peak in the Teton Range, in the U.S. state of Wyoming. Located within Grand Teton National Park, the peak is immediately southwest of Grand Teton, from which it is separated by a broad high ridge at , known to local climbers as the Lower Saddle. The Middle Teton Glacier is located on the eastern slopes of the peak. Middle Teton is a classic pyramidal alpine peak and is sometimes included as part of the Cathedral Group of high Teton peaks. The Teton Range is the youngest mountain chain in the Rocky Mountains, beginning its uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Middle Teton and the other peaks of the range into their current shapes. From the Lower Saddle, a distinctive feature known as the black dike appears as a straight line running from near the top of the mountain down . The black dike is a basaltic intrusion that occurred long after the surrounding rock was formed. Climbing The first re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Owen (Wyoming)
Mount Owen () is the second highest peak in the Teton Range, Grand Teton National Park in the U.S. state of Wyoming. The peak is named after William O. Owen, who organized the first documented ascent of the Grand Teton in 1898. Mount Owen is part of the Cathedral Group of high Teton peaks, a collection of peaks in the central section of the range that are particularly rugged. The long Teton Range is the youngest mountain chain in the Rocky Mountains, and began its uplift 9 million years ago, during the Miocene. Several periods of glaciation have carved Mount Owen and the other peaks of the range into their current shapes. Valhalla Canyon is situated on the west slopes of Mount Owen. Climbing After two failed attempts in 1927 and one in 1928, Mount Owen was first climbed in 1930, and was one of the last of the major Teton peaks to be climbed. Numerous routes have been explored, ranging in difficulty from Class 5.1 to 5.10 See also * Geology of the Grand Teton area Refe ...

Barns Grand Tetons
A barn is an agricultural building usually on farms and used for various purposes. In North America, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain.Allen G. Noble, ''Traditional Buildings: A Global Survey of Structural Forms and Cultural Functions'' (New York: Tauris, 2007), 30. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, cow house, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. In mainland Europe, however, barns were often part of integrated structures known as byre-dwellings (or housebarns in US literature). In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing. Etymology The word ''barn'' comes fro ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and rock), sometimes referred to as glacial till, that occurs in both currently and formerly glaciated regions, and that has been previously carried along by a glacier or ice sheet. It may consist of partly rounded particles ranging in size from boulders (in which case it is often referred to as boulder clay) down to gravel and sand, in a groundmass of finely-divided clayey material sometimes called glacial flour. Lateral moraines are those formed at the side of the ice flow, and terminal moraines were formed at the foot, marking the maximum advance of the glacier. Other types of moraine include ground moraines (till-covered areas forming sheets on flat or irregular topography) and medial moraines (moraines formed where two glaciers meet). Etymology The word ''moraine'' is borrowed from French , which in turn is derived from the Savoyard Italian ("mound of earth"). ''Morena'' in this case was derived from Provenà ...

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Late Glacial Maximum, was the most recent time during the Last Glacial Period that ice sheets were at their greatest extent. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing drought, desertification, and a large drop in sea levels. Based on changes in position of ice sheet margins dated via terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets commenced 33,000 years ago and maximum coverage was between 26,500 years and 19–20,000 years ago, when deglaciation commenced in the Northern Hemisphere, causing an abrupt rise in sea level. Decline of the West Antarctica ice sheet occurred between 14,000 and 15,000 years ago, consistent with evidence for another abrupt rise in the sea level about 14,500 years ago. Glacier fluctuations around the Strait of Magellan suggest the peak in glacial surface area was constrained to betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taggart Lake
Taggart Lake is located in Grand Teton National Park, in the U. S. state of Wyoming. The natural lake is located at the terminus of Avalanche Canyon. A number of hiking trails can be found near the lake including a roundtrip hike commencing from the Taggart Lake Trailhead parking area. The lake is approximately one mile south of Bradley Lake reckoned by trail distance. A 2005 study of the water quality of the lakes in Grand Teton National Park indicated that the lakes in the park were still considered pristine and that they had not been impacted by air or water pollution. Taggart lake was named after William Rush Taggart, an assistant surveyor to Frank Bradley as part of the Snake River division of the Hayden expedition of 1872 to document the geology and topography of the Yellowstone area. Other lakes in the area were named after the below individuals: * Bradley Lake - Frank Bradley * Taggart Lake - William Rush Taggart * Leigh Lake - Beaver Dick Leigh * Jenny Lake - Jenny Leig ...

Jenny Lake
Jenny Lake is located in Grand Teton National Park in the U.S. state of Wyoming. The lake was formed approximately 12,000 years ago by glaciers pushing rock debris which carved Cascade Canyon during the last glacial maximum, forming a terminal moraine which now impounds the lake. The lake is estimated to be deep and encompasses . Jenny Lake is considered to be a major focal point in Grand Teton National Park, with many hiking trails, scenic boat rides, and quick access to the major climbing routes onto the tallest peaks of the Teton Range. Jenny and Jackson Lakes are the only lakes in Grand Teton National Park where motorboats are permitted; both lakes have scenic tours available. A 2005 study of the water quality of the lakes in Grand Teton National Park indicated that all the lakes in the park were still considered pristine and that they had not been impacted by air or water pollution. Jenny Lake is a starting point for many day and overnight hiking trips. The Jenny Lake Tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. This is apparent in the Lake District in Northwestern England where post-glacial sediments are normally between 4 and 6 metres deep. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-bloc ...
