Academy Black Granite Boulder Free Stacks.  Stacks can be made permanent with pinned steel rods. The natural shape of the boulders create a ‘only one of a kind on earth’ arrangement.

To create a ‘Monument to Earthquakes’ Art City Stone Specialists can build a seismic garden of free stacked boulders in a safety zone area in a community prone to earthquakes.  Fallen boulders would explain to a community there was an earthquake.
