North Cascades National Park
North Cascades National Park is an American national park in the state of Washington. At more than , it is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through the reservoirs of Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national par ...

Cirque
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 ...

Boston Peak
Boston Peak is a tall peak in the North Cascades in the U.S. state of Washington and within North Cascades National Park. At in elevation it is the 26th highest peak in Washington. Its nearest higher neighbor is Buckner Mountain, to the east. Description Boston Peak is located just north of the border between Chelan and Skagit counties. It is connected to Buckner Mountain, to the east by the sharp arête of Ripsaw Ridge, which follows the county line. Sahale Peak is located directly south of Boston Peak, connected by a short ridge. A longer ridge to the northwest connects Boston Peak with Forbidden Peak and Sharkfin Tower. The north slopes of Boston Peak and Ripsaw Ridge are covered by Boston Glacier, the largest glacier of the North Cascades. The west side of Boston Peak is covered by Quien Sabe Glacier. Davenport Glacier occupies the southeast side of Boston Peak. To the east of the high summits of Forbidden Peak, Boston Peak, and Sahale Mountain the land slopes down into ...

Washington (state)
Washington (), officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital; the state's largest city is Seattle. Washington is often referred to as Washington state to distinguish it from the nation's capital, Washington, D.C. Washington is the 18th-largest state, with an area of , and the 13th-most populous state, with more than 7.7 million people. The majority of Washington's residents live in the Seattle metropolitan area, the center of trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sahale Mountain
Sahale Mountain is a jagged, glaciated mountain, in North Cascades National Park, in northern Washington state. The summit of Sahale Mountain is referred to as Sahale Peak. It is south of its higher neighbor, Boston Peak, and the saddle between the two is lower than Sahale's summit. Quien Sabe Glacier is to the west of the ridge between the two peaks while Davenport Glacier is in a cirque east of this ridge and above Horseshoe Basin. Sahale Glacier is south of the summit and east of Sahale Arm, a ridge that extends southwest from Sahale to Cascade Pass. The name Sahale may originate from a Northwest Native American word meaning "high place," "falcon," or "sacred." Climbing Sahale Peak is noted for its panoramic views and is popular among mountaineers. The least technical route follows the Sahale Arm from the Cascade Pass Trail to the Sahale Glacier. From the glacier there is a 3–4 climb to the summit. Another option is to traverse from the Sahale Arm onto the Quien Sabe Glac ...

Boston Glacier
Boston Glacier is located in a large cirque below several mountain peaks in North Cascades National Park in the U.S. state of Washington. Approximately long but nearly wide, it is the largest glacier in North Cascades National Park. Extending in an arc from the north of Forbidden Peak, it is flanked by Boston Peak to the southwest and Buckner Mountain at its eastern margin, between which it lies below the arête known as Ripsaw Ridge. Another arête extending between Boston Peak, Sharkfin Tower, Forbidden Peak and further north separate Boston Glacier from the nearly adjoining Quien Sabe and Forbidden Glaciers. Boston Glacier has been in an overall state of retreat since the end of the Little Ice Age around the year 1850. A moderate advance occurred between 1950 and the mid-1970s; however, the retreat resumed and between 1972 and 2006 its terminus retreated .

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 Mass wasting, also known as mass movement, is a general term for the movement of rock or soil down slopes under the force of gravity. It differs from other processes of erosion in that the debris transported by mass wasting is not entrained in ... 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 language, German equivalent term ''Grat''. Where three or more cirques meet, a pyramidal peak is created. Cleaver A ''cleaver' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glaciers Of The North Cascades
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
