Los Osos Back Bay is a prehistoric Chumash archaeological site in the Los Osos Valley, near the coast in San Luis Obispo County, California.
These ancient Californian Native Americans had a significant settlement, now named "Los Osos Back Bay," on a stabilized sand dune.
[1] It is to the west of the Elfin Forest Natural Area, which has another midden within it.
It is where the native Chumash at the eponymous archaeological site gathered marine resources,[1] as coastal tribes along this part of the California coast regularly did.
