The accidental discovery was made under the Main Ranch House on Santa Rosa Island, California, USA, during the process of lifting the building to construct a new foundation. The site may be at least 10000 years old.

The Main House Ranch was constructed sometime after 1869 and served as a sheep and cattle ranch for more than 150 years. It’s believed to be one of the oldest wood framed structures in Santa Barbara County. Among the finds from the archaeological site are two types of stone tools believed to belong to early North American Paleoindians. According to the researchers these tools were made from local island chert and  were used for hunting and fishing by some of the earliest people on the West Coast. Researchers state that these types of sites serve as evidence of a coastal migration following the North Pacific Rim from the North-east Asia into the Americas.
