Baldface Mountain Volcanic Field

The Baldface Mountain volcanic field is a volcanic field in the Central Interior of British Columbia, Canada. It is located about 25 km (16 mi) east of the Itcha Range on the Chilcotin Plateau. The volcanic field contains at least eight volcanic cones and is one of two volcanic fields in the Anahim Volcanic Belt, the other being the Satah Mountain volcanic field which extends south from the Itcha Range.
