I learned, from someone much wiser than me, that these little cavities are called "tafoni." I'll never forget it 🫶🏼

Bean Hollow State Beach 🧵

1/2 Bean Hollow State Beach is one of the loveliest beaches in California, and lies along Highway 1 near San Mateo County. It is famous for its tafoni, pebbles and beautiful rock.

The “tafoni’ is wind and wave eroded soft sandstone, that captures the pebbles in little pockets. The colorful pebbles are varieties of white agate, red chert, green jade, jasper, and other types of stone, and are washed in from an offshore gravel bed.

Bean Hollow State Park educational sign on Tafoni. It says, “Tafoni are created by a process called “cavernous weathering.” This it the interaction of salt, spray and wind on the rock. The rock here consists of the mudstones, siltstone and sandstones of the Pigeon Point Formation. Tafoni form best in sandstone because it is soft and porous.A tafoni-weathered rock with pockets full of colorful small pebbles.More tafoni weathering.A close up of the colorful pebbles.
