These are two 5-to-10-millimetre-thick (0.20-to-0.39-inch) tephra layers of phonolitic to trachytic composition in the Dease Lake and Finlay River areas of northern British Columbia. [163] Radiocarbon dating of terrestrial plant macrofossils directly overlying the youngest tephra layer suggest an Early Holocene age for this volcanic material. [164]
The Triplex Cones are a group of three cinder cones in northern British Columbia, Canada. [1] They are thought to have last erupted during the Holocene epoch. [ 2 ]
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.
Eve Cone is a well-preserved black cinder cone on the Big Raven Plateau, British Columbia, Canada. [1] 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.
Williams Cone is a satellite cone of Mount Edziza, located 36 km (22 mi) 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 .
Kostal Cone is too young for the commonly used potassium-argon dating technique (usable on specimens over 100,000 years old), and no charred organic material for radiocarbon dating has been found. However, the uneroded structure of the cone with the existence of trees on its flanks and summit have it an area for dendrochronology studies, which ...
Tseax Cone is one of the southernmost volcanoes in the Northern Cordilleran Volcanic Province. [10] This is a broad area of shield volcanoes, lava domes, cinder cones and stratovolcanoes extending from northwestern British Columbia northwards through Yukon into easternmost Alaska.
