Tafoni Filled With Rocks, San Mateo Coast, California
Coastal tafoni are distinctive rock formations found along shorelines, characterized by their intricate, honeycomb-like patterns and smooth, rounded cavities. Formed primarily in sandstone and other granular rocks, these features develop through a combination of salt weathering, where salt crystals from seawater infiltrate and expand within the rock, and thermal stress from temperature fluctuations. The constant action of waves and the presence of salty, moist air accelerate these weathering processes, creating the unique, often visually striking patterns seen in coastal tafoni. These formations not only enhance the natural beauty of coastal landscapes but also serve as important microhabitats for various marine organisms.
