Arizona Moss Rock and Boulders Northern Arizona quarries harvest surface select stone materials with lichens and moss growing on the stone. Stone materials include patio flagstone, large slabs, and boulders. Stone materials are shipped bulked on flatbeds in amounts of 2 to 24 tons throughout the Western USA and beyond. Smaller orders shipped on pallets anywhere requested. Arizona Moss Rock and Boulders are very hard surface rocks made up of sandstone quartzite. These slabs and boulders are harvested from the surface of the bedrock flagstone quarries. This material has been baked in the sun of Northern Arizona for hundreds of years, if not longer, and then covered most winters in snow. The result is a very dark red, sienna-red rock with the additional benefit of lichens or moss growing and covering in full or in patches on the rock.
