Calico Early Man Site

Calico Early Man Site

The history of this site dates back to 1942, when amateur archaeologists discovered what they believed to be primitive stone tools in this area. Fragments were embedded in the sediments of the shoreline of an ancient Pleistocene Era lake, called Lake Manix.

This was the only New World archaeology project undertaken by the renowned archaeologist-paleontologist, Dr. Louis S.B. Leakey. Leakey, and his son, Richard, are well known for their Early Man discoveries at Olduvai Gorge in east Africa. Dr. Leakey first visited the area in 1963. He came to examine artifacts discovered in a commercial excavation by Ruth Dee Simpson, a San Bernardino County archaeologist. Leakey continued to act as Project Director until his death in 1972. Ruth Dee Simpson died in 2000.
