The first Native Americans arrived to the San Diego area between 9,000 and 10,000 cal BP (cal BP is a time standard for uncalibrated carbon dating and begins at 1950 in present time).

These people most likely originated from the North, around the Santa Barbara region. The first records of natives living in Santa Barbara date back to about 11,600 years ago.
Evidence supports the belief that the Batiquitos Lagoon was abandoned between 3500 and 1500 BP. The lagoon may have silted up and populations may have declined due to lack of food. The gap in the archaeological record leaves unanswered questions about what happened to the people. The entire San Diego County region seemed to be abandoned between 7500 years ago and before about 1000 A.D
