Disarticulated burial in Hidden Valley Rockshleter. Adams (1949:63) noted that the burial was associated with grit tempered pottery (Woodland Period) at a depth of 75 cm below the surface. "The bones were in a very poor state of preservation - the skull, mandible, most of the ribs, vertebrae, tarsals, carpals and phlanges were missing."


"Three large, circular fireplaces and a small circular fireplace were found 120 to 150 cm under large rocks..." (Adams 1949: Figure 17B).
