Calico Early Man Archaeological Site


Calico Early Man Site is an active archaeological site where stone tools from at least 50,000 years ago have been found.  These are the earliest dated evidence of human occupation in the Western Hemisphere. 

Calico is also the only site in the Western Hemisphere with which Dr. Louis Leakey was associated.  He was the Project Director here until his death in 1972.

Since 1964 when excavation began three master pits and numerous test pits have uncovered over 11,000 significant quality artifacts--mostly stone tools.  The creators of these tools were probably late Homo erectus or early Homo sapiens neandertalensis.

The site is administered by the Friends of Calico Early Man Site and the Bureau of Land Management.
