Back before California built Interstate 8, a team from University of  Califor
nia at Los Angeles conducted field testing at a prehistoric site in the  
Laguna Mountains (CA-SDI-777) (it had an historic component). I reviewed their  
field notes and collections before returning four years later for the California  
State Division of Highways to conduct my own tests. The UCLA crew  terminated 
excavating arbitrary levels when the number of flaked stone artifacts  
dropped to three. After reviewing all the geological and soils information and  
inspecting the site, I could not understand why they stopped digging at two  
meters. My field crew penetrated those layers with sparse artifacts, which we  
determined were redeposited river sand that carried a few flaked stone  artifacts. 
Below and to a depth of 3.3 meters, an older prehistoric component  lay 
buried. My geology training went into high gear during that test program and  we 
dug straight to bedrock.
