Jul 19, 2010 (A Wilson) - The quarry was developed in a sequence of alternating dolostones of the Thorneloe Fm and limestone. At this location, the rock is dark grey in colour and contains both nodular chert (10%) and numerous sporadic mud seams. The rock is described as nodular calcarenite within a fine-grained carbonate matrix.
