Description: Substantial volcanic rock sourced from the Mt. St. Helens region in Washington State. "3-Man" sized rocks are large pieces, typically weighing between approximately 750 lbs to 1500+ lbs, requiring appropriate machinery (like a mini-excavator or small loader) for safe handling and precise placement. This rock showcases a distinctive porous texture and a captivating range of volcanic colors, including grays, charcoals, reddish-browns, and blacks, with generally angular forms.
Used for: Building large, engineered retaining walls, creating impressive landscape focal points and statement pieces, significant erosion control applications, and constructing substantial naturalistic features in larger scale projects that demand a bold, volcanic aesthetic.
