Shells and other site constituents from eighty-eight horizontal samples, as well as shells from a 3 m deep test unit in the Hoko River Rockshelter were analysed in this study. Results from studying the horizontal distribution of site constituents suggest several use areas in the rockshelter, including a primary refuse area and a major living zone with a principal activity center. An intermediate zone between these two areas represents processing debris for several intertidal species, as well as mixed debris from major refuse dumping and sweeping. An entranceway is depicted by a general mixed debris flow from the front of the rockshelter.
