Background
The Itcha Range, one of the Miocene to Pliocene felsic shield volcano complexes of the Anahim Volcanic Belt in central British Columbia, is capped by a large number of basaltic cinder cones of Pliocene to latest Pleistocene age. The highly dissected complex covers an area of 300 km2. Potassium-Argon dates on the younger pyroclastic cones and tuff rings, primarily in the eastern half of the complex, range from 2.2 to 0.8 million years ago (Ma). The youngest lavas are basanite flows in the NW and NE part of the complex. The freshest and best preserved cinder cone in the center of the shield could be much younger, perhaps as young as the 0.34 Ma - 7100 years before present Nazko cone to the east (Charland et al., 1993). The cone has not been dated and the latest volcanism is most likely of latest Pleistocene age (Hickson et al., 1994).---
