Mosquito Mound is a tuya in east-central British Columbia, Canada, located in Wells Gray Provincial Park. [1]
Tuber Hill is a small 600,000-year-old basaltic stratovolcano that was constructed on the Bridge River highlands when nearby valleys were packed with ice. Tuber Hill is part of the Garibaldi segment of the Canadian Cascade Arc, but is not in the geographic Cascade Range.
The Watts Point volcanic centre is a small outcrop of Pleistocene age volcanic rock at Watts Point in British Columbia, Canada, about 10 kilometres (6 mi) south of Squamish and 40 kilometres (25 mi) north of Vancouver, and just north of Britannia Beach. It is the southernmost volcanic zone in the Squamish volcanic field and of the Garibaldi segment of the Cascade Volcanic Arc. The latest research indicates that it is most likely a subglacial mound. It comprises a continuous mass of sparsely porphyritic highly jointed dacitic lava overlying the mid-Cretaceous Coast Plutonic Complex and overlain locally by clay and of glacial till.
Caribou Tuya is a basaltic subglacial mound in far northwestern British Columbia that began eruptive activity under glacial ice during the Fraser glaciation. Like Ash Mountain and South Tuya, sections of the subglacial mound reveal a consistent stratigraphic progression from pillow lavas to hyaloclastite deposits from the base upward. Locally the sections are capped by subaerial basaltic lava flows. Samples of the glassy pillow basalts and hyaloclastites along with crystalline basalt flows were collected at Caribou Tuya. The volcano is believed to have formed and last erupted during the Pleistocene Epoch.
Kawdy Mountain is a subglacial mound on the Kawdy Plateau, the northernmost sub-plateau of the Stikine Plateau in northwestern British Columbia, Canada. It consists of nearly horizontal beds of basaltic lava, capping outward dipping beds of fragmental volcanic rocks and last erupted in Pleistocene. Kawdy Mountain is one of many basaltic volcanic features of the Stikine Volcanic Belt, which is forming because the North American tectonic plate is stretching slightly as it moves to the west.
Tsekone Ridge, also called Tsekone Peak and Black Knight Cone, is an isolated ridge on the Big Raven Plateau of the Tahltan Highland in northwestern British Columbia, Canada. It is located southeast of Telegraph Creek at the north side of Mount Edziza Provincial Park between Eve Cone and Mount Edziza.
Mount Brew is a rounded mountain in southwestern British Columbia, Canada, located 18 km (11 mi) southwest of Whistler in the Pacific Ranges of the Coast Mountains. A public cabin run by the Varsity Outdoor Club, Brew Hut, is located near the summit. The alpine area is a popular destination for hiking in the summer and backcountry ski touring in the winter and spring.
Ne Ch'e Ddhäwa is the Northern Tutchone name for an eroded tuya approximately 7 km up the Yukon River from Fort Selkirk in the Fort Selkirk Volcanic Field of central Yukon, Canada. It has been described as a cinder cone or a subglacial mound. The volcano erupted subglacially between 2.0 and 2.3 million years ago during the early Pleistocene, erupting hyaloclastite tuffs, breccias, and pillow breccias. These hyaloclastites locally contain exotic clasts and bodies of till melted from an ice sheet during the subglacial eruption.
Wetalth Ridge is an isolated ridge in northern British Columbia, Canada, located 74 km (46 mi) southwest of Tatogga and south of Telegraph Creek. It lies on the southwest side of Little Arctic Lake at the southwest corner of Mount Edziza Provincial Park.
Pillow Ridge is a ridge of the Tahltan Highland in northern British Columbia, Canada, located southeast of Telegraph Creek. It extends northwest from Mount Edziza in Mount Edziza Provincial Park.
Spanish Mump is a subglacial mound in east-central British Columbia, Canada, located in the northeastern corner of Wells Gray Provincial Park.
A subglacial mound (SUGM) is a type of subglacial volcano. This type of volcano forms when lava erupts beneath a thick glacier or ice sheet. The magma forming these volcanoes was not hot enough to melt a vertical pipe right through the overlying glacial ice, instead forming hyaloclastite and pillow lava deep beneath the glacial ice field. Once the glaciers had retreated, the subglacial volcano would be revealed, with a unique shape as a result of their confinement within glacial ice. They are somewhat rare worldwide, being confined to regions which were formerly covered by continental ice sheets and also had active volcanism during the same period. They are found throughout Iceland, Antarctica and the Canadian province of British Columbia.
Meehaz Mountain is a mountain in the Cassiar Country of the Northern Interior of British Columbia, Canada, located on the north side of the headwaters of Teslin River and to the south of the Atsutla Range. It is a product of subglacial volcanism during the Pleistocene period when this area was covered by thick glacial ice, forming a subglacial volcano that never broke through the overlying glacial ice known as a subglacial mound.
Nuthinaw Mountain is a mountain on the Stikine Plateau in northern British Columbia, Canada, located east of Tutsingale Mountain and 72 km (45 mi) northwest of Dease Lake on the north side of Tachilta Lakes. It is a product of subglacial volcanism during the Pleistocene period when this area was covered by thick glacial ice, forming a subglacial volcano that never broke through the overlying glacial ice known as a subglacial mound.
Tutsingle Mountain is a mountain on the Stikine Plateau in northern British Columbia, Canada, located east of Nuthinaw Mountain and northwest of Dease Lake on the northeast side of the Tachilta Lakes. It is a product of subglacial volcanism during the Pleistocene period when this area was covered by thick glacial ice, forming a subglacial volcano that never broke through the overlying glacial ice known as a subglacial mound.
Volcanism of Western Canada has produced lava flows, lava plateaus, lava domes, cinder cones, stratovolcanoes, shield volcanoes, greenstone belts, submarine volcanoes, calderas, diatremes and maars, along with examples of more less common volcanic forms such as tuyas and subglacial mounds.
Little Eagle Cone is a subglacial mound in northwestern British Columbia, Canada, located in the Dark Mountain area. It last erupted during the Pleistocene epoch.
Enid Creek Cone is a subglacial mound in northwestern British Columbia, Canada, located in the Dark Mountain area. It last erupted during the Pleistocene epoch.
Tadekho Hill is an isolated hill in the Northern Interior of British Columbia, Canada, located 64 km (40 mi) southwest of Tatogga and 10 km (6 mi) southwest of Kitsu Peak. It lies at the southwestern end of Mount Edziza Provincial Park.
Chakatah Creek Peak is a subglacial mound in northwestern British Columbia, Canada. It is one of the volcanoes of the Northern Cordilleran Volcanic Province and last erupted in the Pleistocene period.
Tom MacKay Creek Cone is a basalt subglacial mound in northwestern British Columbia, Canada. It is part of the Iskut-Unuk River Cones group and last erupted during the Pleistocene epoch. There is a single vent and a single flow of weathered, fragmented pillow basalt that has a maximum thickness of 30 m (98 ft).
