Washougal Gray Basalt Wall Stone
An irregular, blocky basalt in light to medium gray, quarried in Washougal, Washington just across the Columbia from Portland. The pieces come in varied sizes with flat bedding faces, which makes them easy to stack by hand into a natural-looking wall. The rough, varied shapes give walls a relaxed, organic line, which makes this stone the right pick for dry-stack walls, terraces, and garden borders.
The gray coloring is lighter than the dark gray of standard Columbia River basalt, keeping a soft look while holding the durability and weather resistance of volcanic stone. Coverage runs 14 to 18 square feet per ton stacked, and the mix of sizes lets pieces nest together with little fitting.
