 While volcanoes of the Anahim Volcanic Belt appear to merge laterally with the Chilcotin Group lavas, the particular nature and connection between the Anahim Volcanic Belt and the Chilcotin Group is unknown.However, volcanoes within the Anahim Volcanic Belt usually become younger from coastal British Columbia to near the small city of Quesnel further east, indicating these volcanoes may have formed as a result of the North American Plate passing over a possible mantle plume known as the Anahim hotspot, whereas the Chilcotin Group is related to back-arc basin volcanism.Nazko Cone, a cluster of basaltic cinder cones in the Nazko area west of Quesnel forms the youngest and most easterly part of the Anahim Volcanic Belt with dates of 7,200 years.
