Bowling Ball Beach
The bowling balls at Bowling Ball Beach are concretions that have eroded from the sandstone beds of the Miocene Galloway
Fm. The sandstone bed exposed in the bluff in the top center of the photograph has several concretions that are in the process of forming new bowling balls. As the cliff is worn back by the waves, the hard sandstone concretions are left behind.
Bowling Ball Beach is in Schooner Gulch State Park, between Gualala and Point Arena.
Go at low tide, the bowling balls and the beach are covered at high tide.
