Mountain Ash™ Granite

Mountain Ash Granite is a bold, architectural stone built for projects that demand strength and clarity. Quarried from our Cotton Thomas & Fish Creek Quarries in Moulton, Idaho, it delivers cool gray structure and full-system flexibility. In the Build It Right.™ framework, Mountain Ash spans Surface, Feature, and Finish, allowing you to carry a project from patio to wall to final accent with one cohesive material.

Mountain Ash is a dense natural granite known for its consistent gray base and crystalline mineral texture. As an igneous stone, it offers exceptional compressive strength, freeze-thaw durability, and long-term performance in harsh Mountain West climates.

Functionally, Mountain Ash performs across patios, landscape slabs, full bed veneer, drystack walls, rubble, boulders, and structural features. Its density and mass make it ideal for high-traffic areas, retaining walls, and commercial-grade hardscape applications.

Design-wise, Mountain Ash sharpens modern builds and provides strong contrast against warm quartzites like Autumn Gold and Buckskin. It pairs naturally with Storm Mountain and North River Bluestone for cohesive cool-toned palettes and architectural precision.
