Marin Mix is a premium grade river rock blend featuring smooth, rounded cobbles in an elegant palette of coastal grays, earthy browns, deep plum, olive green, and golden tan. Hand-selected and color-sorted, this vibrant mix brings a polished, contemporary touch to modern landscapes, especially in upscale homes and gardens across Mill Valley, San Rafael, Tiburon, Ross, San Anselmo, Petaluma, Napa, Angwin and Santa Rosa.
 
Each stone is naturally shaped by river erosion, tumbled to a velvety finish, and sorted for consistent size. Whether you’re building a dry creek bed or accenting a modern paver layout, Marin Mix is the perfect fusion of form and function.
