Cowboy Coffee D. G. Basalt Rock Fine Northern California quarry This is a new material to the California landscape market. This a crushed basalt stone product, a dark hard rock material that will stand the test against heavy traffic or just the effects if seasonal weather. Bold rich brown colors with hints a deep green colors. Naming this popular road engineering material for landscape use was easy. When I saw the colors it reminded me right away of the coffee my mother and other horse trainers & riders used to brew out at the ranches morning and night, bold and strong.
