Large Blue Mountain Shale rock brings structure and character to outdoor spaces in a way few other rocks can. These flat, naturally layered stones range from 4 to 10 inches and are ideal for DIY landscapers who want to place stones by hand, create custom landscapes, or build low decorative borders. The flat surfaces make placement easy and the results look intentional without requiring professional installation.

Blue mountain shale rock has a natural color range of blues, oranges, and warm neutrals that complement both modern and rustic landscape styles. The variation from stone to stone means no two placements look exactly alike.

Large shale works best for:

• Informal stepping stone paths
• Low garden borders and edging
• Decorative ground feature placement
• Dry creek bed anchors and accents

Large shale is sold by the ton. One cubic yard of shale is approximately 1.15 tons. Not sure how much you need? Call us at 509-235-4511 and we can help you estimate based on your project area.
