The Insular Mountains are a mountain range of the Pacific Coast Ranges on the coast of British Columbia , Canada . They include the Vancouver Island Ranges and the Queen Charlotte Mountains. The Insular Mountains are rugged, with some of the peaks in Strathcona Provincial Park being more than 2,000 m (6,562 ft) high. The highest among them is the Golden Hinde on Vancouver Iceland , the 2,195 m (7,207 ft).
Although the Coast Mountain Range is commonly referred to as the westernmost range of the Pacific Cordillera (since it is the westernmost stretch of the main land mass at this point), in reality the Insular Mountains are the westernmost range.
geology
The Insular Mountains have not yet fully emerged above sea level , and Vancouver Island and the Haida Gwaii archipelago are just the higher plains of the area that was actually exposed to the sun during the last Ice Age (they had their maximum ice surface about 18,000 years ago). when the continental shelf in this area was a broad coastal plain.
The Insular Mountains were formed when a chain of active volcanic islands (the Insular Islands) hit the North American continent in the Middle Cretaceous . The type of rocks that formed the Insular Mountains are turbidite and pillow lava . Granite plutons are rarely found in island mountains , not so in Coast Mountains . The Insular Mountains area covers an area of 133,879 km² (51,691 mi² ). Seismic activity is common as the Pacific Plate and Juan de Fuca Plate are pushed into the Earth's mantle . Large earthquakes have caused mountains to collapse, landslides and crevices.
During the last cold spell, almost all of these mountains were surrounded by ice. Glaciers that ran down to the Pacific Ocean carved the valleys and led to soil erosion. These valleys were turned into fjords when the ice melted and the sea level rose. Ice age remnants can still be observed today, for example Comox Glacier in the Vancouver Island Ranges .
