Chaos Glacier (Waddington Range)

It flows to the north from Mount Tiedemann for approximately four kilometers before joining the larger Scimitar Glacier. The name was officially adopted in 1978 from field sketches of the area by mountaineer Don Munday. The area's steep terrain makes this an excellent example of a continuous ice fall.Climber's Guide to the Coastal Ranges of British Columbia, January 1967, p.27 file C.1.64 References Glaciers of the Pacific Ranges Waddington Range {{canada-glacier-stub ...

Waddington Range
The Waddington Range is a subrange of the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is only about 4,000 km2 (1,545 sq mi) in area, relatively small in area within the expanse of the range, but it is the highest area of the Pacific Ranges and of the Coast Mountains, being crowned by its namesake Mount Waddington 4,019 m (13,186 ft). The Waddington Range is also extremely rugged and more a complex of peaks than a single icefield, in contrast to the other huge icefield-massifs of the southern Coast Mountains, which are not so peak-studded and tend to have more contiguous icemasses. History The difficulty of access to the core of the massif delayed actual sighting, measurement and climbing of Mount Waddington until 1936; it had only been espied from Vancouver Island by climbers in the 1930s and was at first referred to as Mystery Mountain - because its existence until then had been unknown. Apparently even in First Nations l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Mountains
The Coast Mountains (french: La chaîne Côtière) are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Tiedemann
Mount Tiedemann 3838m (12592 feet), prominence 848m, is one of the principal summits of the Pacific Ranges subdivision of the Coast Mountains of British Columbia. It is located northeast of Mount Waddington in the Waddington Range massif between the Homathko and Klinaklini Rivers. Name origin Mount Tiedemann is named for Herman Otto Tiedemann, who worked for the colonial government under Surveyor-General Joseph Pemberton, designing and supervising construction of Victoria, British Columbia's "Birdcages", the original legislature buildings there, the former courthouse (now the Maritime Museum), the Fisgard Lighthouse and other buildings and churches, all while conducting surveys of the British Columbia and Alaska coast. He was responsible for first bringing water from Elk Lake to the city as a water supply. In 1862, he had accompanied Alfred Waddington on preliminary surveys for the proposed wagon road to the Cariboo goldfields via Bute Inlet and the Homathko River, the demi ...

Don Munday
Walter Alfred Don Munday (1890 – 1950) was a Canadian explorer, naturalist and mountaineer famous for his explorations of the Coast Mountains with his wife Phyllis, and especially for the exploration of the Waddington Range. Early life Don Munday was born and educated in Portage la Prairie, Manitoba and moved to Vancouver, British Columbia with his family in 1909. In World War I, he served in France with the 47th Battalion. Marriage Don met Phyllis in 1918. While on a mountaineering trip an incident occurred which, in Don's words, "lends itself readily to being given a romantic aspect." Don lost his footing on a glacial moraine, and was in danger of slipping into a crevasse. Phyllis jumped to help him restore his balance, and in so doing lost hers. Don managed to grab and steady her until she could regain her feet. They married in February 1920, spending their honeymoon in a cabin on Dam Mountain near Vancouver. Their daughter, Edith was born in 1921, and at 11 weeks she was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icefall
An icefall is a portion of certain glaciers characterized by relatively rapid flow and chaotic crevassed surface, caused in part by gravity. The term ''icefall'' is formed by analogy with the word ''waterfall'', which is a similar phenomenon of the liquid phase but at a more spectacular speed. When ice movement of a glacier is faster than elsewhere, because the glacier bed steepens or narrows, and the flow cannot be accommodated by plastic deformation, the ice fractures, forming crevasses. Where two fractures meet, seracs (or ice towers) can be formed. When the movement of the ice slows down, the crevasses can coalesce, resulting in the surface of the glacier becoming smoother. Ice flow Perhaps the most conspicuous consequence of glacier flow, icefalls occur where the glacier bed steepens and/or narrows. Most glacier ice flows at speeds of a few hundred metres per year or less. However, the flow of ice in an icefall may be measured in kilometres per year. Such rapid flow cannot ...

Glaciers Of The Pacific Ranges
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] |
