Photo Gallery

The Wells Gray-Clearwater volcanic field in the Quesnel Highland of east-central British Columbia contains basaltic cones and lava flows of early Pleistocene-to-Holocene age. Dragon Cone (above) produced lava flows that traveled 14 km down Falls Creek to the Clearwater River. Pleistocene deposits of the volcanic field include plateau-capping lava flows, subglacial mounds and tuyas, and hyaloclastites. Several cones were active during the Holocene, and the latest eruption took place from Kostal cone about 400 years ago.
