Capsule Geology

A 500 metre wide band of Upper Triassic Quatsino Formation (Vancouver Group) limestone extends northwestward from the west shore of Upper Campbell Lake for 1.75 kilometres to the southwest side of Bacon Lake. Underlying basalts of the Upper Triassic Karmut- sen Formation (Vancouver Group) outcrop to the southwest. To the northeast, the limestone contacts granodiorite of the Early to Middle Jurassic Island Intrusions. The band is truncated to the northwest by a northeast trending fault.
