The Garibaldi Volcanic Belt is a northwest–southeast trending volcanic chain in the Pacific Ranges of the Coast Mountains that extends from Watts Point in the south to the Ha-Iltzuk Icefield in the north. This chain of volcanoes is located in southwestern British Columbia, Canada. It forms the northernmost segment of the Cascade Volcanic Arc, which includes Mount St. Helens and Mount Baker. Most volcanoes of the Garibaldi chain are dormant stratovolcanoes and subglacial volcanoes that have been eroded by glacial ice. Less common volcanic landforms include cinder cones, volcanic plugs, lava domes and calderas. These diverse formations were created by different styles of volcanic activity, including Peléan and Plinian eruptions.
The Tuya volcanic field is a volcanic field of tuyas located in far northern British Columbia, Canada, near the border with the Yukon Territory and focused on the area of the Tuya Range, a subrange of the Stikine Ranges of the Cassiar Mountains, though some vents are in the Kawdy Plateau, the northernmost part of the Stikine Plateau. Several small shield volcanoes, and postglacial lapilli cones and lava flows have been reported in this area. The only nonglacial volcanoes in the field are Gabrielse Cone and the West Tuya lava field.
Mount Fee is a volcanic peak in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is located 13 km (8.1 mi) south of Callaghan Lake and 21 km (13 mi) west of the resort town of Whistler. With a summit elevation of 2,162 m (7,093 ft) and a topographic prominence of 312 m (1,024 ft), it rises above the surrounding rugged landscape on an alpine mountain ridge. This mountain ridge represents the base of a north-south trending volcanic field which Mount Fee occupies.
Tuya Butte is a tuya in the Tuya Range of north-central British Columbia, Canada. It is a bit less isolated from other ranges than neighbouring Mount Josephine. Some of the other volcanoes in the area include South Tuya, Ash Mountain, and Mathews Tuya.
Mount Silverthrone, officially named Silverthrone Mountain, is a mountain in the Pacific Ranges of the Coast Mountains of British Columbia, Canada, located over 320 km (200 mi) northwest of the city of Vancouver and about 50 km (30 mi) west of Mount Waddington, British Columbia, Canada. It is the highest peak in the Ha-Iltzuk Icefield, which is the largest icefield in the Coast Mountains south of the Alaska Panhandle.
Crow Lagoon is a little-known volcanic center located north of Prince Rupert, British Columbia, Canada. There are beds of thick, basaltic tephra that are of Holocene age.
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.
Toozaza Peak is a tuya in the Stikine Ranges of the Cassiar Mountains in northern British Columbia, Canada, located in the Iverson Creek. Toozaza Peak is the summit of a north–south aligned ridge between the head of Toozaza Creek and the head of the Jennings River, just south of the Jennings' divide with the Little Rancheria River headwaters. The Little Rancheria and Toozaza Creek are part of the Liard, while the Jennings is part of the Yukon River drainage via Teslin Lake, and the peak therefore stands astride the line of the Continental Divide. It is part of the Tuya Volcanic Field, a volcanic field associated with the Stikine Volcanic Belt, part of the Northern Cordilleran Volcanic Province.
Pyroclastic Peak is the second highest of the five named volcanic peaks immediately south of Mount Cayley in British Columbia, Canada. It is steep and rotten and is located 12 km (7 mi) southwest of Callaghan Lake and 24 km (15 mi) west of Whistler. It is part of the Pacific Ring of Fire that includes over 160 active volcanoes.
Castle Rock is a volcanic plug located 13 km (8 mi) west of Iskut and 8 km (5 mi) northwest of Tuktsayda Mountain in British Columbia, Canada. Castle Rock is part of the Pacific Ring of Fire that includes over 160 active volcanoes and is in the Klastline Group of the Northern Cordilleran Volcanic Province and last erupted in the Pleistocene.
Slag Hill is a subglacial volcano associated with the Mount Cayley volcanic field in British Columbia, Canada. It consists of glassy, augite-phyric basaltic andesite in steep-sided, glassy, finely jointed domes and one small, flat-topped bluff. The finely jointed domes are similar to those of Ember Ridge. There are quench features at Slag Hill, which is suggesting that the volcanic activity was subglacial. Slag Hill was formed throughout the Pleistocene period, but its most recent volcanic activity produced a lava flow on its western lobe that shows no evidence of ice-contact volcanism. This indicates the lava flow was erupted less than 10,000 years ago after the last glacial period.
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.
Cauldron Dome is a tuya in the Mount Cayley volcanic field, British Columbia, Canada. Cauldron Dome is made of coarsely plagioclase-orthophyroxene-phyric andesite lava flows and last erupted during the Holocene. It is in the Garibaldi Volcanic Belt, a portion of the Canadian Cascade Arc.
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.
Pali Dome is a subglacial volcano in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. It is part of the Mount Cayley volcanic field and its elevation is 2,250 m (7,380 ft). For the past 2 million years, the Mount Cayley volcanic field has had interactions between ice and lava which have created some unique landforms and an in-ice drainage system."Pali" comes from the Hawaiian word that means cliff or steep hill, while dome refers to the lava dome, which is when doughy lava flows from a volcanic vent which is usually rounded and flat on top.
The volcanic history of the Northern Cordilleran Volcanic Province presents a record of volcanic activity in northwestern British Columbia, central Yukon and the U.S. state of easternmost Alaska. The volcanic activity lies in the northern part of the Western Cordillera of the Pacific Northwest region of North America. Extensional cracking of the North American Plate in this part of North America has existed for millions of years. Continuation of this continental rifting has fed scores of volcanoes throughout the Northern Cordilleran Volcanic Province over at least the past 20 million years and occasionally continued into geologically recent times.
The Canadian Cascade Arc, also called the Canadian Cascades, is the Canadian segment of the North American Cascade Volcanic Arc. Located entirely within the Canadian province of British Columbia, it extends from the Cascade Mountains in the south to the Coast Mountains in the north. Specifically, the southern end of the Canadian Cascades begin at the Canada–United States border. However, the specific boundaries of the northern end are not precisely known and the geology in this part of the volcanic arc is poorly understood. It is widely accepted by geologists that the Canadian Cascade Arc extends through the Pacific Ranges of the Coast Mountains. However, others have expressed concern that the volcanic arc possibly extends further north into the Kitimat Ranges, another subdivision of the Coast Mountains, and even as far north as Haida Gwaii.
The Mount Cayley volcanic field (MCVF) is a remote volcanic zone on the South Coast of British Columbia, Canada, stretching 31 km (19 mi) from the Pemberton Icefield to the Squamish River. It forms a segment of the Garibaldi Volcanic Belt, the Canadian portion of the Cascade Volcanic Arc, which extends from Northern California to southwestern British Columbia. Most of the MCVF volcanoes were formed during periods of volcanism under sheets of glacial ice throughout the last glacial period. These subglacial eruptions formed steep, flat-topped volcanoes and subglacial lava domes, most of which have been entirely exposed by deglaciation. However, at least two volcanoes predate the last glacial period and both are highly eroded. The field gets its name from Mount Cayley, a volcanic peak located at the southern end of the Powder Mountain Icefield. This icefield covers much of the central portion of the volcanic field and is one of the several glacial fields in the Pacific Ranges of the Coast Mountains.
Mount Cayley is an eroded but potentially active stratovolcano in the Pacific Ranges of southwestern British Columbia, Canada. Located 45 km (28 mi) north of Squamish and 24 km (15 mi) west of Whistler, the volcano resides on the edge of the Powder Mountain Icefield. It consists of massif that towers over the Cheakamus and Squamish river valleys. All major summits have elevations greater than 2,000 m (6,600 ft), Mount Cayley being the highest at 2,385 m (7,825 ft). The surrounding area has been inhabited by indigenous peoples for more than 7,000 years while geothermal exploration has taken place there for the last four decades.
