'''Caribou Tuya''' is a [[basalt]]ic [[subglacial mound]] in far northwestern [[British Columbia]] that began eruptive activity under glacial ice during the Fraser glaciation (25 to 10 [[Annum|ka]]). Like [[Ash Mountain (British Columbia)|Ash Mountain]] and [[South Tuya]], sections of the subglacial mound reveal a consistent stratigraphic progression from [[pillow lava]]s to [[hyaloclastite]] deposits from the base upward. Locally the sections are capped by subaerial basaltic [[lava flows]]. Samples of the glassy [[pillow basalt]]s and hyaloclastites along with [[crystalline]] basalt flows were collected at Caribou Tuya. The volcano is believed to have formed and last erupted during the [[Pleistocene]] Epoch.<ref>{{cite web |url=http://gsc.nrcan.gc.ca/volcanoes/cat/volcano_e.php?id=svb_crt_027 |archive-url=https://web.archive.org/web/20110604154301/http://gsc.nrcan.gc.ca/volcanoes/cat/volcano_e.php?id=svb_crt_027 |archive-date=2011-06-04 |title=Caribou Tuya |publisher=Catalogue of Canadian volcanoes}}</ref>
