Calico Early Man Site, Archaeological site in San Bernardino County, United States.
The archaeological site contains thousands of stone tools, flakes, and artifacts distributed across the Pleistocene alluvial deposits in the Mojave Desert.
Ruth DeEtte Simpson and Louis Leakey initiated systematic excavations at Calico in 1964, revealing potential evidence of early human occupation in North America.
The site includes petroglyphs and sections of ancient pathways linked to the transportation of chalcedony stones by Native American inhabitants.
The excavation area lies 16 kilometers west of Calico Ghost Town and features multiple research zones with distinct geological formations.
Dating methods indicate the stone tools found at Calico could be between 135,000 to 200,000 years old, challenging conventional theories of human arrival in Americas.
