This striking interior fireplace showcases the Quarry Mill's Eagle River natural thin stone veneer with a tightfit mortarless installation. Eagle River is a unique ashlar style linear take on natural moss rock. Moss rock is a collective term used to describe the pieces of stone that are on the top of or halfway within the layer of topsoil. The stone is exposed to the elements and weather. Moss rock is unique in that lichen grows on the pieces over time. The raw pieces are collected and sorted by hand.
