Swiftcurrent Glacier (British Columbia)
Swiftcurrent Glacier is in Glacier National Park in the U.S. state of Montana.The glacier is on the east ( Glacier County) side of the Continental Divide arête known as the Garden Wall. Swiftcurrent Glacier is one of several glaciers that are being monitored to determine stream flow alterations that occur due to glacial retreat. Compared to other glaciers in Glacier National Park, Swiftcurrent Glacier has experienced relatively slow retreat. As of 2005, the glacier had an area of , a 14 percent reduction since 1966. See also *List of glaciers in the United States *Glaciers in Glacier National Park (U.S.) There are at least 35 named glaciers in Glacier National Park (U.S.). At the end of the Little Ice Age about 1850, the area containing the national park had 150 glaciers. There are 25 active glaciers remaining in the park as of 2022. Since the l ...

Cirque Glacier
A cirque glacier is formed in a cirque, a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation in corries often occurs as the result of avalanching from higher surrounding slopes. If a cirque glacier advances far enough, it may become a valley glacier. Additionally, if a valley glacier retreats enough that it is within the cirque, it becomes a cirque glacier again. In these depressions, snow persists through summer months, and becomes glacier ice. Snow may be situated on the leeward slope of a mountain, where it is sheltered from wind. Rock fall from above slopes also plays an important role in sheltering the snow and ice from sunlight. If enough rock falls onto the glacier, it may become a rock glacier. Randklufts may form beneath corrie glaciers as open space between the ice and the bedrock, where meltwater Meltwater is water released by the melting of snow or ice, including glacial ice, tabular icebergs and ice shelves over oceans.

Glacier County, Montana
Glacier County is located in the U.S. state of Montana. As of the 2020 census, the population was 13,778. The county is located in northwestern Montana between the Great Plains and the Rocky Mountains, known to the Blackfeet as the "Backbone of the World". The county is geographically and culturally diverse and includes the Blackfeet Indian Reservation, Glacier National Park, and Lewis and Clark National Forest. The county is bordered by 75 miles of international boundary with two ports of entry ( Piegan and Del Bonita) open year-round and one seasonal (Chief Mountain) international border crossing into Alberta, Canada. Settlements Several small unincorporated communities, one incorporated town, and one incorporated city are located within the county. Cut Bank, the county seat with a population of around 3000, is located in eastern Glacier County, on the edge of the Great Plains. Cut Bank arose from the railroad and agriculture needs of the surrounding area, and was fostere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Continental Divide
A continental divide is a drainage divide on a continent such that the drainage basin on one side of the divide feeds into one ocean or sea, and the basin on the other side either feeds into a different ocean or sea, or else is endorheic, not connected to the open sea. Every continent on earth except Antarctica (which has no known significant, definable free-flowing surface rivers) has at least one continental drainage divide; islands, even small ones like Killiniq Island on the Labrador Sea in Canada, may also host part of a continental divide or have their own island-spanning divide. The endpoints of a continental divide may be coastlines of gulfs, seas or oceans, the boundary of an endorheic basin, or another continental divide. One case, the Great Basin Divide, is a closed loop around an endoreic basin. The endpoints where a continental divide meets the coast are not always definite since the exact border between adjacent bodies of water is usually not clearly defined. T ...

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 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 equivalent term ''Grat''. Where three or more cirques meet, a pyramidal peak is created. Cleaver A ''cleaver'' is a type of arête that separates a unified flow of glacial ice from its uphill side into two glaciers flanking, and flowing parallel to, the ridge. ''Cleaver'' gets its name from the way it resembles a meat cleaver slicing meat into two parts. A cleaver may be t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garden Wall
The Garden Wall is a steep alpine area within Glacier National Park well known during the summer months to be heavily covered in dozens of species of flowering plants and shrubs. Located along the west side of the Continental divide and extending northward from Logan Pass, the Garden Wall can be traversed via the popular Highline Trail and for a distance of over to the Granite Park Chalet. The Going-to-the-Sun Road also passes through portions of the Garden Wall northwest of Logan Pass. The Weeping Wall is a short stretch of the Going-to-the-Sun Road where water cascades over the Garden Wall to the roadway below. The Garden Wall is an arête or rock spine that separates the Many Glacier region of the park from Lake McDonald Lake McDonald is the largest lake in Glacier National Park. It is located at in Flathead County in the U.S. state of Montana. Lake McDonald is approximately 10 miles (16 km) long, and over a mile (1.6 km) wide and 472 feet (130 m) ... vall ...

Glaciers In Glacier National Park (U
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 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 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. Between latitudes 35°N and 35°S, glaciers occur only in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
