Introduction:
The Wells Gray-Clearwater cinder cones are early Pleistocene-to-Holocene age. Pleistocene deposits include plateau-capping lava flows, subglacial mounds and tuyas, and hyaloclastites. Buck Hill Cone was erupted during the latest Pleistocene during the waning stages of the Fraser glaciation. Holocene eruptions took place in the Spanish Creek, Ray Lake and Kostal Lake areas, forming cinder cones and producing lava flows that traveled up to 14 km. A lava flow from Dragon cone is radiocarbon dated at about 7600 years ago, and flows from Flourmill, Kostal, and Spanish Lake Cones rest on glaciated bedrock without an intervening paleosol, suggesting an early Holocene age.---
