 profile at line 0; c, north-south profile at line ElOO. 



stratum 2, a clean yellowish-brown sand up to 12 inches in thickness, 

 overlying stratum 1 between grid lines NlOO and S300 ; and stratum 

 3, the surface member of light- to dark-gray sand which blanketed 

 the entire area. 



Stratum 1 was sterile of cultural material except for the upper 

 3 or 4 inches, where a few chipped stone implements and flint chips 

 representing a preceramic occupation of the site were found. Similar 

 lithic material continued throughout strata 2 and 3, but ceramics 

 occurred only in stratum 3 and the upper part of stratum 2.
