Tafoni

Tafoni at Salt Point State Park, Sonoma County, California.

Tafoni (singular: tafone) are cavities that develop in granular rock. Tafoni are commonly defined as small (less than 1 cm (0.39 in)) to large (greater than 1 meter (3.3 ft)) cavity features that develop in either natural or manmade, vertical to steeply sloping, exposures of granular rock (e.g., granite, sandstone) with smooth concave walls, and often round rims and openings. Recognized subcategories of tafoni include honeycomb, stonelace, alveolar (less than 2 cm (0.79 in)), sidewall, basal, nested, and relic tafoni. It is also commonly synonymous with nido d’ape roccioso in Italian.

Current research suggests they are polygenic in origin with some form of haloclastic control.
