Blocky, linear weathered boulders with flat top and bottom that are ideal for stacking large boulder retaining walls. Color tones of grays, browns, tans, subtle reds, and earthy greens from the moss and lichen, give these boulders lots of character.  Sizes of 18″-30″ depth x 24” – 72” long x 12” – 24” tall. Approximate coverage of 10 face feet per ton
