Shumla’s presentations are an opportunity for us to share developing insights and data from our ongoing research efforts. Since review and revision are an integral part of the scientific research process, our interpretations are subject to change as new data are collected and other lines of evidence are considered. Our research primarily utilizes scientific, archaeological, and ethnographic methods; however Shumla recognizes and affirms other ways of understanding and knowing, especially Indigenous Traditional Knowledge.
