Franklin Glacier
Franklin Glacier is a mountain glacier in the Waddington Range of the Pacific Ranges in southwestern British Columbia, Canada. It lies at the head of the Franklin River adjacent to Mount Waddington, the highest mountain entirely within British Columbia. The name of the glacier was officially adopted in 1928 after having been submitted by mountaineer Don Munday in August 1927 for its association with the Franklin River. It is the namesake of the Franklin Glacier Complex, a heavily eroded geologic feature consisting of dikes, subvolcanic intrusions and overlying volcanic rocks. A base camp was established on the Franklin Glacier on June 23, 1934, by climbers Neal Carter Neal Marshall Carter (December 12, 1902 – March 3, 1978) was a Canadian marine biologist, cartographer, photographer, mountaineer and surveyor. He is most famous for his explorations in British Columbia, especially in the Coast Mountains where ..., Alan Lambert, Alec Dalgleish and Eric Brooks as part of ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

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#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, 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.

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.

Mount Waddington
Mount Waddington, once known as Mystery Mountain, is the highest peak in the Coast Mountains of British Columbia, Canada. Although it is lower than Mount Fairweather and Mount Quincy Adams, which straddle the United States border between Alaska and British Columbia, Mount Waddington is the highest peak that lies entirely within British Columbia. It and the subrange which surround it, known as the Waddington Range, stand at the heart of the Pacific Ranges, a remote and extremely rugged set of mountains and river valleys. It is not as far north as its extreme Arctic-like conditions might indicate, and Mount Waddington and its attendant peaks pose some of the most serious expedition mountaineering to be had in North America — and some of the most extreme relief and spectacular mountain scenery. From Waddington's fang to sea level at the heads of Bute and Knight Inlets is only about 20 miles; across the gorges of the Homathko and the Klinaklini Rivers stand mountains almo ...

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] |
Franklin Glacier Complex
The Franklin Glacier Complex is a deeply eroded volcano in the Waddington Range of southwestern British Columbia, Canada. Located about northeast of Kingcome, this sketchily known complex resides at Franklin Glacier near Mount Waddington. It is over in elevation and because of its considerable overall altitude, a large proportion of the complex is covered by glacial ice. Magmatic activity of the Franklin Glacier Complex spanned roughly four million years from the Late Miocene to the Early Pleistocene, with the most recently identified volcanic eruption having taken place around 2.2 million years ago. The existence of thermal springs near the complex implies that magmatic heat is still present. It has therefore been of interest to geothermal exploration. Geography The area lies in one of British Columbia's many territorial divisions called the Range 2 Coast Land District.

Dike (geology)
A dike or dyke, in Geology, geological usage, is a sheet of rock that is formed in a Fracture (geology), fracture of a pre-existing rock body. Dikes can be either Intrusive rock, magmatic or Sedimentary rock, sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subvolcanic Rock
A subvolcanic rock, also known as a hypabyssal rock, is an intrusive igneous rock that is emplaced at depths less than within the crust, and has intermediate grain size and often porphyritic texture between that of volcanic rocks and plutonic rocks. Subvolcanic rocks include diabase (also known as dolerite) and porphyry. Common examples of subvolcanic rocks are diabase, quartz dolerite, microgranite, and diorite. See also * Cone sheet * Dike (geology) * Igneous intrusion * Sill (geology) In geology, a sill is a tabular sheet intrusion that has intruded between older layers of sedimentary rock, beds of volcanic lava or tuff, or along the direction of foliation in metamorphic rock.

Intrusion
In geology, an igneous intrusion (or intrusive body or simply intrusion) is a body of intrusive igneous rock that forms by crystallization of magma slowly cooling below the surface of the Earth. Intrusions have a wide variety of forms and compositions, illustrated by examples like the Palisades Sill of New York and New Jersey; the Henry Mountains of Utah; the Bushveld Igneous Complex of South Africa; Shiprock in New Mexico; the Ardnamurchan intrusion in Scotland; and the Sierra Nevada Batholith of California. Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). Intrusive igneous rocks are classified separately from extrusive igneous rocks, generally on the basis of their mineral content. The relative amounts of quartz, alkali feldspar, plagioclase, and feldspathoid is particularly important in classifying intrusive igneous rocks. Intrusions ...

Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces.
