Costa Rica is known for its holes, and in particular following the rainy season on the roads. I have a fondness for holes and a collection of mounds. These mounds range in material composition, but they tend to be made from organic matter. In composition they are created and range from additive to subtractive processes.
The canopy of the rain forest and the sea graciously provided multiples of each. Termites formed these mounds for a nest. Grains of sand that were trapped by sea and swirled themselves into a frenzy to form these inverted mounds in this stone.
The termites stayed in Guiones… The stone made it back to NYC.
