A quarry in limestone & sandstone located west of Inglewood. The quarry produces grey & red Whirlpool sandstone of Silurian age for use as flagstone. The limestone, also Silurian, caps the sandstone. Orange to white celestite occurs as bladed & tabular aggregates at the contact of limestone and the sandstone as well as a thin vuggy unit of limestone just above the sandstone. Copper minerals occur in the vuggy limestone and at the limestone-sandstone interface extending a few centimeters into the sandstone.
