Tenchen Glacier
Tenchen Glacier is located on the eastern flank of Mount Edziza in northwestern British Columbia, Canada. It lies within an immense cirque whose headwall has breached the eastern side of Mount Edziza's summit volcanic crater, crater. At the head of Tenchen Glacier are icefalls that drape down shear, cliffs from the breached eastern crater rim; permanent ice fills the summit crater. Meltwater from Tenchen Glacier feeds Tenchen Creek which eventually merges with Kakiddi Creek. The name of the glacier was suggested by the Geological Survey of Canada on November 19, 1979, and eventually became official on November 24, 1980. ''Tenchen'' is derived from the Tahltan words ''ten'' and ''chen'', which mean ''ice'' and ''dirty'' respectively. The name of this glacier is a reference to its debris-covered surface. Geology The Tenchen cirque is the product of erosion that gradually enlarged an initial scar formed by an explosive eruption that blew away part of the eastern summit crater rim. H ...

Mountain 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 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] |
