Research done by the Far Western Anthropological Research Group/Daron Duke has pushed the time of the Western Stemmed Tradition back further into the Paleoindian period, with dating as far back as 12,000 years ago. One of the points in the study from Utah's Great Salt Lake region tested showed elephant/probiscidean blood residue, showing use for large thrusting and throwing spears. This artifact is one of the largest known, and is a complete and undamaged example of the regional type.   (cast copyright Occpaleo 2020)
