Ha-Iltzuk Icefield
The Ha-Iltzuk Icefield is an icefield in the central Pacific Ranges of the Coast Mountains in British Columbia, Canada. It is the largest icefield in the Coast Mountains south of the Alaska Panhandle, with an area of . It is located on the west side of the Klinaklini River and the Waddington Range. The highest summit in the icefield is Mount Silverthrone, which is a mountain on the northeast edge of a circular, wide, deeply dissected caldera complex called the Silverthrone Caldera. The southern half of the icefield is named the Silverthrone Glacier and flows west, joining the Klinaklini Glacier just above that glacier's terminus, where its outflow is short but very large, and joins the Klinaklini River within a few kilometres. The Klinaklini Glacier constitutes the northern half of the icefield, and off its northwest edge a glacial tongue produces the head of the Machmell River. The name Ha-Iltzuk Icefield does not appear in government gazettes. The term is almost certainly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Complex Volcano
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. Stratovolcanoes can also form a large caldera that gets filled in by a lava dome, or else multiple small cinder cones, lava domes and craters may develop on the caldera's rim. Although a comparatively unusual type of volcano, they are widespread in the world and in geologic history. Metamorphosed ash flow tuffs are widespread in the Precambrian rocks of northern New Mexico, which indicates that caldera complexes have been important for much of Earth's history. Yellowstone National Park is on three partly covered caldera complexes. The Long Valley Caldera in eastern California is also a complex volcano; the San Juan Mountains in southwestern Colorado are formed on a group of N ...

Homathko Icefield
The Homathko Icefield is an icefield in British Columbia, Canada. Officially named the Homathko Snowfield from 1950 until the current name was adopted in 1976, it is one of the largest icefields in the southern half of the Coast Mountains, with an area of over . It is located between Chilko Lake and the Homathko River, and lies across the Great Canyon of that river to the east of the Waddington Range. Although adjacent to Mount Queen Bess, the Homathko Icefield is largely an expanse of ice, about across, ringed by relatively minor peaks and distinguished, relative to the other Coast Mountains icefields, by lack of any major ones. The Lillooet Icecap and the Compton Névé, both similar in size to the Homathko Icefield but much more peak-studded, lie to the Homathko Icefield's southeast across the Southgate River which bends around the icefield-massif's southern flank to reach the head of Bute Inlet adjacent to the mouth of the Homathko River. The icefield is essentially one large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lillooet Icecap
The Lillooet Icecap, also called the Lillooet Icefield or the Lillooet Crown, is a large icefield in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is about northwest of the towns of Pemberton and Whistler, and about north of Vancouver, British Columbia. The Lillooet Icecap is one of the largest of several large icefields in the Pacific Ranges which are the largest temperate-latitude glacial fields in the world. At its maximum extent including its glacial tongues it measures east to west and north to south; its central icefield area is approximately in diameter. The Lillooet Icecap is the source of several major rivers which radiate out from it in a wheel pattern. The Lillooet River is fed by the Lillooet Glacier on the icefield's southern flank and runs southeast via Pemberton to Harrison Lake. The Bridge River is fed by the Bridge Glacier on the icefield's eastern flank and runs east to the town of Lillooet. On the icefield's n ...

List Of Glaciers
A glacier ( ) or () is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world. Glaciers by continent Africa Africa, specifically East Africa, has contained glacial regions, possibly as far back as the last glacier maximum 10 to 15 thousand years ago. Seasonal snow does exist on the highest peaks of East Africa as well as in the Drakensberg Range of South Africa, the Stormberg Mountains, and the Atlas Mountains in Morocco. Currently, ...

Heiltsuk
The Heiltsuk or Haíɫzaqv , sometimes historically referred to as ''Bella Bella'', are an Indigenous people of the Central Coast region in British Columbia, centred on the island community of Bella Bella. The government of the Heiltsuk people is the Heiltsuk Nation, though the term is also used to describe the community. Its largest community is Bella Bella. They should not be confused with the Salish-speaking Nuxalk (Nuxalkmc) peoples ("People of Bella Coola Valley (Nuxalk)"), who were formerly usually called Bella Coola, an Anglicization of the Heiltsuk term Bíbḷxvḷá (singular: Bḷ́xvḷá, meaning: "stranger"). History Ancestors of the Heiltsuk (Haíɫzaqv) have been in the Central Coast region of British Columbia since at least 7190 BCE. The Heiltsuk (Haíɫzaqv) are the main descendants of Haíɫzaqvḷa(Heiltsuk)-speaking people and identify as being from one or more of five tribal groups: W̓úyalitx̌v (Wuyalitxv) (Seaward Tribe or Seaward Division; outsid ...

Silverthrone Caldera
The Silverthrone Caldera is a potentially active caldera complex in southwestern British Columbia, Canada, located over northwest of the city of Vancouver and about west of Mount Waddington in the Pacific Ranges of the Coast Mountains. The caldera is one of the largest of the few calderas in western Canada, measuring about long (north-south) and wide (east-west). Mount Silverthrone, an eroded lava dome on the caldera's northern flank that is high, may be the highest volcano in Canada. The main glaciers in the Silverthrone area are the Pashleth, Kingcome, Trudel, Klinaklini and Silverthrone glaciers. Most of the caldera lies in the Ha-Iltzuk Icefield, which is the largest icefield in the southern half of the Coast Mountains; it is one of the five icefields in southwestern British Columbia that thinned between the mid-1980s and 1999 due to global warming. Nearly half of the icefield is drained by the Klinaklini Glacier, which feeds the Klinaklini River. The Silverthrone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caldera
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a Volcanic crater, crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish language, S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
