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.
Acatenango is a stratovolcano in Guatemala, close to the city of Antigua. It is part of the mountain range of the Sierra Madre. The volcano has two peaks, Pico Mayor and Yepocapa which is also known as Tres Hermanas. Acatenango is joined with Volcán de Fuego and collectively the volcano complex is known as La Horqueta.
The Black Tusk, known as Q̓elqámtensa ti Skenknápa in the St'at'imcets (Lillooet) language and as T'ákt'akmúten tl'a Ín7inyáx̱a7en in the Sḵwx̱wú7mesh (Squamish) language, is a stratovolcano and a pinnacle of volcanic rock in Garibaldi Provincial Park of British Columbia, Canada. At 2,319 m (7,608 ft) above sea level, the upper spire is visible from a great distance in all directions. It is particularly noticeable from the Sea-to-Sky Highway just south of Whistler, British Columbia. Distinctive and immediately identifiable, The Black Tusk is among the best known mountains in the Garibaldi Ranges of the Coast Mountains. The volcano is part of the Garibaldi Volcanic Belt which is a segment of the Canadian Cascade Arc, but it is not within the geographic boundary of the Cascade Range.
The Mount Meager massif is a group of volcanic peaks in the Pacific Ranges of the Coast Mountains in southwestern British Columbia, Canada. Part of the Cascade Volcanic Arc of western North America, it is located 150 km (93 mi) north of Vancouver at the northern end of the Pemberton Valley and reaches a maximum elevation of 2,680 m (8,790 ft). The massif is capped by several eroded volcanic edifices, including lava domes, volcanic plugs and overlapping piles of lava flows; these form at least six major summits including Mount Meager which is the second highest of the massif.
Heart Peaks, originally known as the Heart Mountains, is a mountain massif in the Northern Interior of British Columbia, Canada. It is 90 km (56 mi) northwest of the small community of Telegraph Creek and just southwest of Callison Ranch. With a maximum elevation of 2,012 m (6,601 ft), it rises above the surrounding landscape on the Nahlin Plateau, which is part of the western Stikine Plateau. Heart Peaks has been an area of prospecting since the 1980s with the discovery of precious metals.
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.
The Vulcan's Thumb is a rock pinnacle in the Pacific Ranges of southwestern British Columbia, Canada. It is the largest of a number of slender pinnacles protruding from the sharp summit ridge of Pyroclastic Peak, which forms part of the Mount Cayley massif.
The Cascade Volcanoes are a number of volcanoes in a volcanic arc in western North America, extending from southwestern British Columbia through Washington and Oregon to Northern California, a distance of well over 700 miles (1,100 km). The arc formed due to subduction along the Cascadia subduction zone. Although taking its name from the Cascade Range, this term is a geologic grouping rather than a geographic one, and the Cascade Volcanoes extend north into the Coast Mountains, past the Fraser River which is the northward limit of the Cascade Range proper.
Mount Job is one of six named volcanic peaks of the Mount Meager massif in British Columbia, Canada. It is a pile of rubble held together by volcanic ash and sand. The main summit of Mount Job is hard to climb because of difficult access and its horribly loose rock.
Plinth Peak, sometimes called Plinth Mountain, is the highest satellite cone of the Mount Meager massif, and one of four overlapping volcanic cones which together form a large volcanic complex in the Garibaldi Volcanic Belt of the Canadian Cascade Arc. It is one of the most recently formed volcanic formations of the Mount Meager massif.
Pylon Peak is the southernmost of six named volcanic peaks comprising the Mount Meager massif in British Columbia, Canada. Two pinnacled ridges extend from Pylon and are named respectively the Pylons and the Marionettes. Pylon Peak overlooks the Meager Creek Hot Springs.
Perkin's Pillar was a vertical pillar of volcanic rock of the Mount Meager massif in southwestern British Columbia, Canada. It existed on the steep north flank of Capricorn Mountain. The upper half of Perkin's Pillar broke sometime in June 2005 and only a jagged sliver remains of the previously mighty summit.
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.
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 Plinth Assemblage, also known as the Plinth Formation, is an accreted terrane of igneous rocks in southwestern British Columbia, Canada, located just north of the Lillooet River and on the northern flank of the Mount Meager massif. It is named after Plinth Peak, a peak made of Plinth Assemblage rocks.
The Capricorn Assemblage, also known as the Capricorn Formation, is a geological formation comprising the central portion of the Mount Meager massif in southwestern British Columbia, Canada. It is named after Capricorn Mountain, the third highest subsidiary peak of Meager. The assemblage was formed during a period of volcanic activity about or less than 90,000 years ago.
The Pylon Assemblage is an accreted terrane of igneous rocks in southwestern British Columbia, Canada, located about 150 km (93 mi) north of Vancouver. It is named after Pylon Peak, a summit of the Mount Meager massif. Two units make up the Pylon Assemblage, although the youngest unit comprises nearly 100% of the assemblage.
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.
