Geology
Baldface Mountain is a
trachytic–
phonolitic volcanic cone in the
Anahim Volcanic Belt that was active 2.37 million years ago. A locally extensive field of volcanic cones is centered on Baldface Mountain and is judiciously called the
Baldface Mountain volcanic field (BMVF). Baldface Mountain is the largest edifice in this volcanic field and is one of the few BMVF volcanoes known to have produced
felsic

rocks.
A small trachytic knob just south of Baldface Mountain has a slightly older age of 2.52 million years and is the oldest known BMVF feature. The close proximity between this knob and Baldface Mountain indicates that they might be part of a larger volcanic centre and/or a single period of intermittent
volcanism.
