| Profile of 35-foot wall in Unit 35, looking north, showing limestone fragments in Stratum 7. The 5-foot-long measure stick rests at a depth of 198 inches. Located largely outside the drip line of the shelter, Stratum 7 is made up of talus deposits and possibly flood materials. Based on archeological evidence, it appears to be a continuation of the interior cave deposits (Stratum 5), although it is different in color and texture. Photo by Albert Redder. |
