Triplex Cone

Last updated

Triplex Cone is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period. [1]

Cinder cone A steep conical hill of loose pyroclastic fragments around a volcanic vent

A cinder cone is a steep conical hill of loose pyroclastic fragments, such as either volcanic clinkers, cinders, volcanic ash, or cinder that has been built around a volcanic vent. They consist of loose pyroclastic debris formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30–40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped crater at the summit.

British Columbia Province of Canada

British Columbia is the westernmost province of Canada, located between the Pacific Ocean and the Rocky Mountains. With an estimated population of 5.016 million as of 2018, it is Canada's third-most populous province.

Canada Country in North America

Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border. Its capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra. Consequently, its population is highly urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies widely across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons.

Eve Cone mountain in Canada

Eve Cone is a well-preserved black cinder cone on the Big Raven Plateau, British Columbia, Canada. It is one of the 30 cinder cones on the flanks of the massive shield volcano of Mount Edziza that formed in the year 700, making it one of the most recent eruptions on the Big Raven Plateau and in Canada. Eve Cone stands by itself in the middle of the Desolation Lava Field and its distinctive shape can be seen from a long distance. Commonly photographed, Eve Cone is covered by light yellow pumice from a close by but unknown vent.

Cracker Creek Cone is a small cinder cone in northwestern British Columbia. A large lava flow that partly filled Ruby Creek may have originated from this cone. The lower west side of the cone appears to be partly covered by glacial till suggesting that the cone is older than the most recent glacial advances down Ruby Creek. Cracker Creek Cone is in the Northern Cordilleran Volcanic Province and is one of the three young volcanic cones in the Atlin Volcanic Field.

Williams Cone is a satellite cone of Mount Edziza, located 36 kilometers east of Telegraph Creek. It lies just off the northern edge of the Tencho Icefield and is one of the many postglacial cinder cones that lie on the Mount Edziza volcanic complex. Williams Cone last erupted about 1,350 years ago along with other nearby volcanoes, such as the well-preserved Eve Cone.

The Desolation Lava Field is a volcanic field associated with the Mount Edziza volcanic complex in British Columbia, Canada. It covers 150 km2 (58 sq mi) on the northern end of the Mount Edziza volcanic complex and is the largest area of the youngest lava flows. The longest lava flow from the field and the volcanic complex, is about 12 km (7.5 mi) long. Eve Cone, in the middle of the field, is one of the most symmetrical and best preserved cinder cones in Canada.

Kana Cone is a red nested cinder cone in northern British Columbia, Canada, located northeast of Eve Cone in Mount Edziza Provincial Park.

Snowshoe Lava Field

The Snowshoe Lava Field is a volcanic field associated with the Mount Edziza volcanic complex in northern British Columbia, Canada. It is on the southern end of the Big Raven Plateau and is an area of young lava flows.

Twin Cone is a cinder cone in northern British Columbia, Canada. It is thought to have last erupted in the Holocene period.

Second Canyon Cone, also called Canyon Creek Cone is a cinder cone in the Boundary Ranges of the Coast Mountains in northwestern British Columbia, Canada. It is a volcanic feature of the Iskut-Unuk River Cones which is part of the Northern Cordilleran Volcanic Province and formed in the past 10,000 years of the Holocene 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.

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.

Walkout Creek Cone is a cinder cone in northwestern British Columbia, Canada. It 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 volcanic field called the Snowshoe Lava Field.
