The Raven Black Quarry is located approximately 42 kilometres northeast of Harrison Hot Springs on Cogburn Creek road.

The owner is W. Streicek and the operator is Granite Creations and Stonework.

Large, blocky outcrops are exposed in the bottom part of a V-shaped valley. The stone is sound, lacking microfractures. The homogeneity is affected by scattered, long, 1 to 2 millimetre wide, very dark green veinlets. The anorthosite is part of the Coast Plutonic complex.

Raven Black is a medium black, medium-grained anorthosite. It has an even texture and uniform colour. The rock is comprised of plagioclase with very small amounts of biotite, chlorite and trace magnetite. It has no alteration, staining or fabric. It takes a fair to good polish (7-8/10) with some minor pitting on biotite. There are some narrow (1-2 mm), through going black to very dark green fractures, healed with chlorite, that mar the uniformity of the rock.
