Glacial Boulders: Stones and rocks that were exposed by a glacier and then left behind after the glacier melted. Perfect for building walls, ponds, water features, borders and beyond.
Glacial Boulders continue to be our specialty and our staple product. You can confidently view Duro Rock as your trusted supply line from the field directly to your job site. Our smallest glacial boulders start at 4-6” sort and then increase 6” increments from a 6” rock all the way up to 60” boulder.
