Sub-Stratum 5B: Lower member—third red

This sub-stratum is found 4 inches up in the clean cave fill. It was formed by a ½-inch layer of red clay being deposited and staining about 2 inches of white fill below.  As shown in the wall profile photo at right, three thin fingers of clay extended inward from a red clay deposit at the front of the shelter. This sub-stratum is the lowest of the three.

The red clay layer was devoid of artifacts, although bone fragments of small animals were found in the cave fill above.
