Fossil Creek Stone is a quartzitic sandstone formed over 300 million years ago in the deserts of Eastern New Mexico. Formed by water deposits with a higher compressive strength (16,400 psi) and a lower absorption rate (2%), Fossil Creek Stone can be utilized in any climate and last for generations. It is a color consistent material, with its neutral beige to earth tone buff coloring. Wavy surface is great for outdoor pool decks, providing for solid traction when the stone gets wet. Beautiful natural cleft texture give flagstone a wonderfully appealing charm, combined with the strength and durability of natural stone. Fossil Creek Wall Rock 2″-3″ refers to large, thick, horizontally palletized pieces used for durable pool decks, and rugged stepping stones for landscaping. These heavy-duty jumbo pieces are perfect for high-traffic, load-bearing, or structural applications (vertical cladding).
