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 256 feet (78 m) deep and encompasses 1,191 acres (482 ha). 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jenny Lake Trail
The Jenny Lake Trail is a long hiking trail which circles Jenny Lake located in Grand Teton National Park in the U.S. state of Wyoming. The trail begins at the Jenny Lake campground or can be accessed at several other trailheads. One of the most popular and easiest hikes in the park, the trail provides pedestrian access to the Cascade Canyon Trail and is overlapped by the Valley Trail (Grand Teton National Park), Valley Trail along the west side of Jenny Lake.

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 from 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 ...

Moraine
A moraine is any accumulation of unconsolidated debris (regolith and Rock (geology), 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 are those 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 language, French , which in turn is derived from the Savoyard dialect, Savoyard Italian ('mound of e ...

Smallpox
Smallpox was an infectious disease caused by Variola virus (often called Smallpox virus), which belongs to the genus '' Orthopoxvirus''. The last naturally occurring case was diagnosed in October 1977, and the World Health Organization (WHO) certified the global eradication of the disease in 1980, making smallpox the only human disease to have been eradicated to date. The initial symptoms of the disease included fever and vomiting. This was followed by formation of ulcers in the mouth and a skin rash. Over a number of days, the skin rash turned into the characteristic fluid-filled blisters with a dent in the center. The bumps then scabbed over and fell off, leaving scars. The disease was transmitted from one person to another primarily through prolonged face-to-face contact with an infected person or rarely via contaminated objects. Prevention was achieved mainly through the smallpox vaccine. Once the disease had developed, certain antiviral medications could poten ...

Beaver Dick
Richard "Beaver Dick" Leigh (9 January 1831, Manchester – 29 March 1899, Wilford, Idaho) was an English-American trapper, scout, and guide at the end of the 19th century, primarily in the area now known as Jackson Hole, Wyoming, United States. He has been called "possibly the West's last mountain man." He was the guide for Ferdinand Vandeveer Hayden, F. V. Hayden's survey of the Teton Range in 1872. Leigh Lake was named for Richard Leigh, and nearby Jenny Lake for his first wife, by Hayden's expedition. He corresponded frequently with his longtime friend, Charles B. Penrose, leaving behind diaries and letters that provide a personal, historical, and geographical documentation of the area. He was mentioned by Theodore Roosevelt in 1892, as a local hunter around Two Ocean Pass. His moniker "Beaver Dick" was reportedly given to him by Brigham Young as a tribute to his trapping skills. In 1964, Beaver Dick Park was established near Rexburg, Idaho. Despite what the The New York Times, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Pollution
Water pollution (or aquatic pollution) is the contamination of Body of water, water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater pollution, groundwater. This form of pollution can lead to many problems. One is the environmental degradation, degradation of aquatic ecosystems. Another is spreading Waterborne diseases, water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the Water resources, water resource. Sources of water pollution are either p ...

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 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 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 Snake River fine- ...

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-shaped hill, breast-like shapes of its peaks. Another theory says the range is named for the Teton Sioux (from Thítȟuŋwaŋ), 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 (Wyoming), Mount Owen (), Teewinot Mountain, Teewinot (), Middle Teton () and South Teton ().

Last Glacial Maximum
The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent between 26,000 and 20,000 years ago. Ice sheets covered much of Northern North America, Northern Europe, and Asia and profoundly affected Earth's climate by causing a major expansion of deserts, along with a large drop in sea levels. Based on changes in position of ice sheet margins dated via cosmogenic nuclide, terrestrial cosmogenic nuclides and radiocarbon dating, growth of ice sheets in the southern hemisphere commenced 33,000 years ago and maximum coverage has been estimated to have occurred sometime between 26,500 years ago and 20,000 years ago. After this, deglaciation caused 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 fl ...

Grand Teton National Park
Grand Teton National Park is a national park of the United States 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 south of Yellowstone National Park, to which it is connected by the 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. In the early 19th century, the first European explorers encountered the eastern Shoshone people. Between 1810 and 1840, the region attracted fur trading companies that vied for control of the lucrative beaver pelt trade. U.S. government expeditions to the region commenced in the mid-19th century, with the first permanent whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier
A glacier (; or ) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and 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“Glacier, N., Pronunciation.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/7553486115. Accessed 25 Jan. 2025. 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 ever ...
