Quarried from our Cotton Thomas & Fish Creek Quarries – Moulton, Idaho, Mountain Ash Granite is true igneous stone dense, durable, and built for real climates.

Featuring cool gray tones with natural mineral fleck and subtle crystalline movement, this granite aggregate brings structure and architectural weight to landscape designs. It reads clean and grounded without feeling sterile.

This isn’t decorative gravel that breaks down over time. This is granite, hard and stable.

Mountain Ash Granite Decorative Aggregate functions as both a Surface and Finish product when you Build It Right.™

As a Surface, it can serve as compacted pathway material or durable ground cover for xeriscape projects when installed correctly.

As a Finish, it defines borders, strengthens transitions, and adds contrast around patios and vertical elements.

Because it’s quarry-direct from Moulton, Idaho, you get consistent regional sourcing, proven freeze-thaw performance, and material that performs in the same Mountain West environments your projects live in.

We’ll help you Build It Right.™ Build It Beautiful.™

FAQs

Q: What does “minus” mean?
A: “Minus” indicates the material includes fines up to the listed size, allowing it to compact more effectively than washed rock.

Q: Which size is best for pathways?
A: ⅝" minus compacts well and is commonly used for walkable surfaces.

Q: Is granite suitable for freeze-thaw climates?
A: Yes. Granite’s density and low absorption make it highly durable in cold-weather environments.

Q: Does it require edging?A: Yes. Containment with metal, strip, or stone edging helps maintain clean lines and prevent migration.
