Boulder Glacier (Montana)
Boulder Glacier is located in the U.S. state of Montana in Glacier National Park (U.S.). The glacier is situated to the north of Boulder Peak and west of the 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 .... Between 1966 and 2005, Boulder Glacier lost more than 75 percent of its surface area. As of 2005 the glacier was measured to cover only , and no longer met the threshold often cited as the minimal area to qualify as an active glacier. Boulder Glacier was photographed in 2007 by researchers from the U.S. Geological Survey and those images demonstrate that the glacier has almost disappeared. Earlier images taken in 1910 depict a glacier that was far larger than what was recorded in 2007. See also * List of glaciers in the United States * Glaciers in ...

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.

Flathead County, Montana
Flathead County is in the U.S. state of Montana. At the 2020 census, its population was 104,357, making it the state's fourth most populous county. Its county seat is Kalispell. Its numerical designation (used in the issuance of license plates) is 7. Its northern border is on the state's north border, making it contiguous with the Canada–US border, facing British Columbia. Flathead County comprises the Kalispell, Montana Micropolitan Statistical Area, with neighboring Lake County following soon after. History Flathead County was founded in 1893. Some sources cite the supposed practice of the Salish tribe flattening infants' heads as the origin of the name Flathead, but there is no record of Salish Indians ever having that appearance. Geography The county includes much of Flathead Lake, the Flathead Valley, and the Flathead River. These natural treasures, originated by glaciers, are named for the unique geological formation of a broad flat valley surrounded by mountains ...

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 ...

Boulder Glacier 1910
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive. In common usage, a boulder is too large for a person to move. Smaller boulders are usually just called rocks or stones. The word ''boulder'' derives from ''boulder stone'', from the Middle English ''bulderston'' or Swedish ''bullersten''.

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] |
