Stratum 9: Yellow Clay

This stratum lies atop the red "Plainview" sands at the back of the shelter and is about 12 inches thick.  Yellow in color, its texture is very tough and waxy, and it is so difficult to screen that part of it was thrown out without screening.  The deposit is culturally sterile, although a few small unmodified animal bones have been found along with small flecks of charcoal.
