At the bridge over Canyon Creek approximately 1.4 kilometers from the Telkwa High road-Old Babine lake road intersection there is a well exposed outcrop of medium to dark grey well bedded siltstone and sandstone that dips moderately to the east. These rocks are mapped as part of the Bulkley Canyon formation of the Lower Cretaceous Skeena Group. These tilted beds are further evidence that Lower Cretaceous and older strata in the Bulkley valley graben were uplifted and folded during a pre mid Cretaceous contractional tectonic event.
