The Stone Seed Fountains and Sculptures that we create at Mariposa are made of dry stacked stone, built using no mortar or glue. Our stone seed features are either free stacked or smoothed down with a grinder. The dimensions of each of our stone seed features are set according to the Golden Mean proportions. The Golden Mean is a mathematical proportion, found all over in nature, in seeds, in shells, in eggs, in flowers and in trees. As a fountain feature, butterflies and birds are easily able to access water.
