Gunnison Basalt

Gunnison Basalt is an excellent choice for interior and exterior applications. It is a durable, hard stone which is resistant to freeze-thaw cycles. Its medium dark gray color and small markings are relatively consistent. Architects specify this natural basalt for interior flooring, exterior paving stone, stair treads, fireplace surrounds and stone wall cladding. Gunnison Basalt is available in honed, cascade and polished finishes.
