==Geology== The range contains rocks deformed by the Antler orogeny of Late Devonian to early Mississippian age. Along the Roberts Mountain thrust fault, which was named for the range, a terrane of oceanic island arc volcanic rocks and sediments were emplaced over the pre-existing Devonian to Silurian carbonates, sandstones and shales of the coastal margin of the continent.<ref>Crafford, A.
