11,000-Year-Old Seafaring Indian Sites revealing Chert crescent tool from San Miguel Island discovered on California Island. It's “definitive evidence” of ancient Paleoindian occupation, about half of them having been dated to 11,000 to 12,000 years ago, making their inhabitants some of the earliest known settlers of North America’s West Coast.
