Background:Nazko Cone, the easternmost and youngest volcano of the Anahim volcanic belt in the Chilcotin-Nechako Plateau was formed in three episodes of activity, the first of which took place during a Pleistocene interglacial stage about 0.34 million years ago. The second stage produced a large hyaloclastite scoria mound erupted beneath the Cordilleran ice sheet during the late Pleistocene. The final activity occurred about 7200 years ago, forming a compound subaerial cinder cone that overtopped the hyaloclastite mound and produced two small lava flows that traveled about 1 km to the west. An airfall tephra blanket extends several km to the north and east of the cone.--- Source: GVP Nazko volcano information |
