Jack's Jump is a subglacial volcano in east-central British Columbia, Canada, located in south-central Wells Gray Provincial Park. [1]
Level Mountain is a massive complex volcano in the Northern Interior of British Columbia, Canada. It is located 50 km (31 mi) north–northwest of Telegraph Creek and 60 km (37 mi) west of Dease Lake on the Nahlin Plateau. With a maximum elevation of 2,190 m (7,190 ft), it is the third highest of five large complexes in an extensive north–south trending volcanic zone. Much of the mountain is gently-sloping; when measured from its base, Level Mountain is about 1,100 m (3,600 ft) tall, slightly taller than its neighbour to the northwest, Heart Peaks. The lower, broader half of Level Mountain consists of a shield-like edifice while its upper half has a more steep, jagged profile. Its large summit is dominated by the Level Mountain Range, a small mountain range with prominent peaks cut by deep valleys. These valleys serve as a radial drainage for several small streams that flow from the volcano. Meszah Peak is the only named peak in the Level Mountain Range.
The Anahim hotspot is a hypothesized hotspot in the Central Interior of British Columbia, Canada. It has been proposed as the candidate source for volcanism in the Anahim Volcanic Belt, a 300 km (190 mi) long chain of volcanoes and other magmatic features that have undergone erosion. This chain extends from the community of Bella Bella in the west to near the small city of Quesnel in the east. While most volcanoes are created by geological activity at tectonic plate boundaries, the Anahim hotspot is located hundreds of kilometres away from the nearest plate boundary.
The Powder Mountain Icefield, also called the Powder Mountain Icecap and the Cayley Icefield, is a glacial field in the Pacific Ranges of southwestern British Columbia, Canada, about 20 kilometres (12 mi) west of Whistler and about 90 kilometres (56 mi) north of Vancouver. On the west side of the icefield is the valley of the Squamish River, while on its east is the Callaghan Valley, which is the setting for the Nordic facilities for the 2010 Winter Olympics.
The volcano Tacaná is the second highest peak in Central America at 4,060 metres (13,320 ft), located in the Sierra Madre de Chiapas of northern Guatemala and southern Mexico. It is also known in Mexico as Volcán Tacina.
Maitland Volcano is a heavily eroded shield volcano in the Northern Interior of British Columbia, Canada. It is 83 km (52 mi) southeast of the small community of Telegraph Creek in what is now the Klappan Range of the northern Skeena Mountains. This multi-vent volcano covered a remarkably large area and was topped by a younger volcanic edifice. Little remains of Maitland Volcano today, limited only to eroded lava flows and distinctive upstanding landforms created when magma hardened within the vents of the volcano.
Powder Mountain, 2,347 m (7,700 ft), is a volcanic summit in the Powder Mountain Icefield in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada.
Little Ring Mountain, also called Little Ring Peak, is a tuya in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It lies at the head of the Squamish and Soo Rivers. Part of the Mount Cayley volcanic field, its most recent eruption most likely occurred during the Fraser Glaciation.
Cache Hill is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period. Once used as an airdrop for food and supplies by the Geophysical Survey of Canada, hence its name, it is located north of Raspberry Pass in Mount Edziza Provincial Park.
Camp Hill is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period.
Dark Mountain, formerly also known as Black Mountain, is a mountain in the Tanzilla Plateau of the Northern Interior of British Columbia, Canada, located northeast of the settlement of Dease Lake, near Cry Lake.
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.
Keda Cone, sometimes mistakenly spelled Kena Cone, is a cinder cone in northwestern British Columbia, Canada, located in the Snowshoe Lava Field of Mount Edziza Provincial Park. It last erupted during the Holocene epoch.
Klastline Cone is a cinder cone in northwestern British Columbia, Canada, located near Mount Edziza in Mount Edziza Provincial Park. It last erupted during the Pleistocene epoch.
Nanook Dome is a lava dome in northwestern British Columbia, Canada, located just northeast of Mount Edziza in Mount Edziza Provincial Park. It last erupted during the Pleistocene epoch.
Glacier Dome is a lava dome in northwestern British Columbia, Canada, located near Mount Edziza in Mount Edziza Provincial Park. It last erupted during the Pleistocene epoch.
Iskut Canyon Cone, also known as Iskut River Cone, is a cinder cone of the Iskut-Unuk River Cones group in northwestern British Columbia, Canada, located on the steep southern flank of the Iskut valley near its junction with Forrest Kerr Creek. It last erupted during the Holocene epoch.
Fort Selkirk Vent is a geological name for a cinder cone in central Yukon, Canada, located just east of Fort Selkirk along the Yukon River.
Mess Lake Cone is a cinder cone in northwestern British Columbia, Canada. It is polygenetic in nature, having erupted more than once throughout its eruptive history. Mess Lake Cone is one of the volcanoes that produced young basaltic lava flows in the central portion of the Mount Edziza volcanic complex in the past 10,000 years. These basaltic lava flows form a north–south trending volcanic field called the Mess Lake Lava Field.
Jack Gordon Souther was an American-born Canadian geologist, volcanologist, professor and engineer. He contributed significantly to the early understanding of recent volcanic activity in the Canadian Cordillera. Many of his publications continue to be regarded as classics in their field, even now several decades after they were written.
