Comments
EgPs-48: Magne and Ives (1991: 107-108) summarize findings at this site, reporting it to be the most complex of several sites on the alluvial fan. Of several cultural horizons, two occur below a tephra layer, possibly Mazama tephra, which is situated at 76 cm depth. The upper one contains only bison bones and no lithic artifacts. The lower one contains bison, bighorn sheep, a large siltstone flake, and a small quartz crystal with quartz crystal debitage. Newton (1991: 116-119) presents a generalized profile based on several backhoe tests.
