Jenny Lake (Montana)
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 Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Grand Teton National Park
Grand Teton National Park is an American national park in northwestern Wyoming. At approximately , the park includes the major peaks of the Teton Range as well as most of the northern sections of the valley known as Jackson Hole. Grand Teton National Park is only south of Yellowstone National Park, to which it is connected by the National Park Service–managed John D. Rockefeller Jr. Memorial Parkway. Along with surrounding national forests, these three protected areas constitute the almost Greater Yellowstone Ecosystem, one of the world's largest intact mid-latitude temperate ecosystems. The human history of the Grand Teton region dates back at least 11,000 years when the first nomadic hunter-gatherer Paleo-Indians began migrating into the region during warmer months to pursue food and supplies. In the early 19th century, the first white explorers encountered the eastern Shoshone natives. Between 1810 and 1840, the region attracted fur trading companies that vied fo ...

Teton County, Wyoming
Teton County is a county in the U.S. state of Wyoming. As of the 2020 United States Census, the population was 23,331. Its county seat is Jackson. Its west boundary line is also the Wyoming state boundary shared with Idaho and the southern tip of Montana. Teton County is part of the Jackson, WY- ID Micropolitan Statistical Area. Teton County contains the Jackson Hole ski area, all of Grand Teton National Park, and 40.4% of Yellowstone National Park's total area, including over 96.6% of its water area (largely in Yellowstone Lake). Previously a staunchly Republican county, which produced Governor and U.S. Senator Clifford Hansen, Teton has become the most Democratic county in Wyoming, following a broader national trend of affluent and college-educated voters drifting towards the political party. In 2020, Joe Biden beat Donald Trump 67.10% to 29.58% in Teton, an overwhelming margin that was the most for a Democrat ever in the county. History Teton County was created February ...

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 ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Cascade Canyon
Cascade Canyon is located in Grand Teton National Park, in the U.S. state of Wyoming. The canyon was formed by glaciers which retreated at the end of the last glacial maximum approximately 15,000 years ago. Today, Cascade Canyon has numerous polished glacial erratics, hanging cirques and a U-shape as evidences that demonstrate that glaciers once filled the canyon to a depth of at least . Rock debris that was transported out of the canyon by glacial motion formed moraines which now impound the waters of Jenny Lake which is located at the base of the canyon. Cascade Creek now flows where the glaciers once did and the numerous waterfalls, such as the tall Hidden Falls, found within the gorge are popular destinations with tourists. The canyon is immediately west of Jenny Lake. The Cascade Canyon Trail follows the length of the canyon and is one of the most heavily used hiking trails in the park. The canyon can be reached from the Jenny Lake campground after a level hike of al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...

Teton Range
The Teton Range is a mountain range of the Rocky Mountains in North America. It extends for approximately in a north–south direction through the U.S. state of Wyoming, east of the Idaho state line. It is south of Yellowstone National Park and most of the east side of the range is within Grand Teton National Park. One theory says the early French voyageurs named the range ' ("the three nipples") after the breast-like shapes of its peaks. Another theory says the range is named for the Teton Sioux (from ThÃtÈŸuÅ‹waÅ‹), also known as the Lakota people.Ullrich, Jan. (2008). ''New Lakota Dictionary''. Lakota Language Consortium. It is likely that the local Shoshone people once called the whole range ', meaning "many pinnacles". The principal summits of the central massif, sometimes referred to as the Cathedral Group, are Grand Teton (), Mount Owen (), Teewinot (), Middle Teton () and South Teton (). Other peaks in the range include Mount Moran (), Mount Wister (), Buck Mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jackson Lake (Wyoming)
Jackson Lake is in Grand Teton National Park in northwestern Wyoming. This natural lake was enlarged by the construction of the Jackson Lake Dam, which was originally built in 1911, enlarged in 1916 and rebuilt by 1989. As part of the Minidoka Project the top of the lake is used by farmers in Idaho for irrigation purposes under water rights legislation that was enacted prior to the establishment of Grand Teton National Park. The lake is the remnant of large glacial gouging from the neighboring Teton Range to the west and the Yellowstone Plateau to the north. The lake is primarily fed by the Snake River, which flows in from the north, and empties at Jackson Lake Dam. Jackson Lake is one of the largest high altitude lakes in the United States, at an elevation of above sea level. The lake is up to long, wide and deep. The water of the lake averages below , even during the summer. Numerous species of fish inhabit the lake including nonnative brown and lake trout and the native S ...
