Mount Silverthrone, officially gazetted as Silverthrone Mountain, is a mountain in Regional District of Mount Waddington, British Columbia, located over 320 km (199 mi) northwest of the city of Vancouver and about 50 km (31 mi) west of Mount Waddington, British Columbia, Canada. There are many notable lists of mountains around the world Typically a list of mountains becomes notable by first being listed or defined by an author or group (e See also List of volcanoes Western Canada is commonly thought to occupy a gap in the Pacific Ring of Fire, although that is not actually true Here is a List of Cascade volcanoes, ie Volcanoes in the Pacific Northwest of North America.

The first mountaineering visit at Mount Silverthrone was by the famous pioneering climbing group of Don and Phyllis Munday in 1936 by walking up the Klinakini Glacier from the head of Knight Inlet. Walter Alfred Don Munday (1890 – 1950 was a Canadian Explorer, naturalist and Mountaineer famous for his explorations of the Coast Mountains Phyllis B Munday CM (née James (born 1894 died 1990 was a Canadian Mountaineer, Explorer, naturalist and Humanitarian Year 1936 ( MCMXXXVI) was a Leap year starting on Wednesday (link will display the full calendar of the Gregorian calendar.

Because Silverthrone is heavily glaciated, Don Munday called the mountain "home of the snows". Walter Alfred Don Munday (1890 – 1950 was a Canadian Explorer, naturalist and Mountaineer famous for his explorations of the Coast Mountains ^[1] It has notoriously wet weather. This is why the Klinaklini Glacier descends to only about 300 m (984 ft) above sea level. The extensive icefields around Mount Silverthrone are receding and are small compared to their former extent, but they are an impressive indication of how much of British Columbia looked 10,000 years or more ago. Silverthrone contains one of the few calderas buried beneath the ice caps of western Canada, another example is Mount Edziza in far northwestern British Columbia, which is almost 2 km (1 mi) wide. Mount Edziza is a Stratovolcano in the Stikine Country of northwestern British Columbia, Canada.

Geology

Mount Silverthrone is an eroded lava dome on the northeast edge of a large caldera complex called the Silverthrone Caldera. In Volcanology, a lava dome or plug dome is a roughly circular Mound -shaped protrusion resulting from the slow eruption of Felsic Lava A caldera is a cauldron-like volcanic feature formed by the collapse of land following a volcanic eruption The Silverthrone Caldera is a potentially active Caldera complex in southwestern British Columbia, Canada, located over northwest of the city of It lies within the Coast Plutonic Complex, which is the single largest contiguous granite outcropping in the world. Granite (ˈɡrænɪt is a common and widely occurring type of intrusive, Felsic, igneous rock. The plutonic and metamorphic rocks extend approximately 1,800 kilometers on the coast of British Columbia, southwestern Yukon and southeastern Alaska. In Geology, an intrusion is a body of Igneous rock that has Crystallized from molten Magma below the surface of the Earth. Metamorphic rock is the result of the transformation of an existing rock type the protolith, in a process called Metamorphism, which means "change Yukon (ˈjuːkɒn is the westernmost and smallest of Canada's three territories. Alaska ( Аляска Alyaska) is a state in the United States of America, in the northwest of the North American continent In addition, Garibaldi, Meager, Cayley and Silverthrone areas are of recent volcanic origin. Mount Garibaldi is a potentially active Stratovolcano in the Squamish-Lillooet Regional District of British Columbia, north of Vancouver, Mount Meager, also called the Meager Group, Meager Mountain, Mount Meager Volcanic Complex or Meager Creek Volcanic Field (sometimes mistakenly Mount Cayley is a potentially active Stratovolcano in Squamish-Lillooet Regional District of southwestern British Columbia, Canada. The volcanic terrain in the Silverthrone area is very similar to the Mount Meager volcanic complex further south. Mount Meager, also called the Meager Group, Meager Mountain, Mount Meager Volcanic Complex or Meager Creek Volcanic Field (sometimes mistakenly However, there is much more ice.

The mountain and the surrounding area may be the northernmost section of the Cascade Volcanic Arc, but scientific study has been very limited due to its extremely remote location. The Cascade Volcanoes (also known as the Cascade Volcanic Arc or the Cascade Arc) are a number of Volcanoes in a Volcanic arc in western Some geological references suggest that it represents the northernmost of the Cascade Volcanic Arc, because the Pemberton Volcanic Belt is usually merged with the Garibaldi Volcanic Belt,^[2][3][4] but its relationship to volcanism caused by the Cascadia subduction zone (i. The Pemberton Volcanic Belt is an eroded Miocene Volcanic belt at a low angle near Mount Meager, British Columbia, Canada. The Cascadia Subduction zone is a Subduction zone, a type of convergent plate boundary that stretches from northern Vancouver Island to e. the Cascade Volcanic Arc) has not been firmly established. Silverthrone may also be the highest volcano in Canada, but even its elevation is not definitely known. Plate tectonics and hotspots Divergent plate boundaries At the Some references state an elevation as high as 3,160 m (10,367 ft), but the current topographic map shows contours only as high as 2,865 m (9,400 ft), and no spot elevation is given. In addition, it is unclear whether the highest point is of volcanic origin or not, since the summit is covered with permanent snow and ice, and the composition of the underlying rock is unknown.

Mount Silverthrone is perhaps the most heavily glaciated volcanic complex in southwestern British Columbia. "Glacial" and "Glaciation" redirect here For the geological periods see Glacial period. It has a topographic prominence of approximately 975 m (3,199 ft), greater than any other volcano in southwestern British Columbia.

Skiing and recreation

Skiing on Mount Silverthrone includes skiing on the largest ice field in the southern Coast Mountains, the Ha-Iltzuk Icefield. Snow skiing is a group of sports utilizing Skis as primary equipment It is skiable over 1,500 m (4,921 ft), possibly over 2,700 m (8,858 ft) down to the Pacific Ocean. The Pacific Ocean is the largest of the Earth 's Oceanic divisions ^[5] The easiest access to Mount Silverthrone is by air travel, starting from the rural community of Tatla Lake, landing on the major part of the Ha-Iltzuk Icefield. Air travels can also be made into logging camps at Owikeno Lake to the west or at the start of Knight Inlet to the southwest, followed by long hiking and skiing methods. Logging is the process in which Trees are cut down for Forest management and Timber. Owikeno Lake, also; Owekeeno Lake, Owekano Lake, Oweekayno Lake and other spellings (pron Knight Inlet is one of the principal inlets of the British Columbia Coast, and the largest of the major inlets in the southern part of the Coast
