Chief Cliff is an extremely durable dark grey quartzite. Quartzite forms from quartz rich sandstone undergoing metamorphosis resulting in a compact rock composed of recrystallized interlocking quartz grains. Quartzite is so durable that in nature it typically forms ridges with little or no soil or vegetation. Chief Cliff contains iron oxides (rust and other minerals) which can be seen in streaks and on exposed surfaces causing earth tones which characterize the rock. Chief Cliff thin veneer is available in squares and rectangles, ledge, and random shapes.
