A hard, fine-grained sandstone member of the Upper Cretaceous Nanaimo Group containing disseminated biotite was quarried for building stone. Fresh rock is blue but weathers to a buff colour. Curving horizontal joints and other irregular partings divide the rock into irregular masses. The stone retains its original colour very well.

The product of this quarry was used chiefly for the tower of the Episcopal Church in New Westminster, and for a building at the corner of Carroll and Cordova streets in Vancouver. No production figures are available.
