Storm Mountain Flagstone is a natural metaquartzite stone featuring rugged dark gray tones with occasional red rust accents, offering a timeless and durable look for outdoor spaces. Produced by Southwest Boulder & Stone, this flagstone is sold exclusively by the pallet at Costco and is available as a seasonal in-store item at select warehouse locations.

Each pallet covers approximately 100 square feet and consists of large, irregularly shaped stones ranging from 24 to 48 inches in size with a thickness of 1 to 2 inches. The stone is palletized vertically in a "stand-up" configuration. Due to the size and weight of the pieces, professional mason installation is recommended for best results.

Storm Mountain Flagstone is well suited for patios, walkways, stepping stone pathways, pool areas, retaining walls, water features, and stone veneer applications. Its natural variation in shape, size, and color gives each installation a unique, organic appearance that blends seamlessly into garden and landscape designs.
