The mountain is one of two hydrological apexes of North America; it is a major triple divide between three great drainage basins. Water falling on Snow Dome's summit may flow into streams that drain into the Pacific Ocean (via the Bush River and the Columbia River ), the Arctic Ocean (via the Athabasca River ), and Hudson Bay (via the North ...
One of the first volcanoes to erupt during the Big Raven eruptive period was Tennena Cone which formed high on the western flank of Ice Peak. [166] It issued basaltic magma under an ice sheet during the Last Glacial Maximum, under an expansion of Mount Edziza's ice cap during the Younger Dryas between 12,900 and 11,600 years ago or during a ...
A long-quiet yet massive super volcano, dubbed the "Long Valley Caldera," has the potential to unleash a fiery hell across the planet, and the magma-filled mountain has a history of doing so.
Mount Edziza, a stratovolcano in northwestern British Columbia A topographic map of Canada, showing elevations shaded from green (lower) to brown (higher). Volcanic activity is a major part of the geology of Canada and is characterized by many types of volcanic landform, including lava flows, volcanic plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, submarine volcanoes ...
Water vapor cloud; 2). Lake; 3). Ice; 4). Layers of lava and ash; 5). Stratum; 6). Pillow lava; 7). Magma conduit; 8). Magma chamber; 9). Dike. A subglacial volcano, also known as a glaciovolcano, is a volcanic form produced by subglacial eruptions or eruptions beneath the surface of a glacier or ice sheet which is then melted into a lake by ...
Big Ben (previously known as Big Ben Peak, Old Ben Mountain, Emperor William Peak and Kaiser Wilhelm-Berg) [1] is a volcanic massif that dominates the geography of Heard Island in the southern Indian Ocean. It is a stratovolcano with a diameter of about 25 km (16 mi). Its highest point is Mawson Peak, which is 2,745 m (9,006 ft) above sea level.
Mount Melbourne is a 2,733-metre-high (8,967 ft) ice-covered stratovolcano in Victoria Land, Antarctica, between Wood Bay and Terra Nova Bay.It is an elongated mountain with a summit caldera filled with ice with numerous parasitic vents; a volcanic field surrounds the edifice.
There are fumaroles on the mountain, which show Mount Shasta is still alive. [citation needed] The worst-case scenario for an eruption is a large pyroclastic flow, similar to that which occurred in the 1980 eruption of Mount St. Helens. Since there is ice, such as Whitney Glacier and Mud Creek Glacier, lahars would also result.
