One of the key goals of lithic raw material analysis is to discern patterns in the distribution that might reflect human activity. Most lithic raw materials in Minnesota are widespread in bedrock and glacial till preventing the tracking of a material from a point of origin to a point of use or discard. Grand Meadow Chert (GMC) has a relatively small source area in the southeastern corner in Minnesota and was not moved across Minnesota by glacial activity. GMC stone tools that occur in archaeological samples across southern Minnesota were used as a case study to model the movement of stone from quarry to tool use and ultimately to discard areas. Finished tools (not debitage) were assessed from institutionally archived collections and private collections across the state. Three mathematical models were compared to the data gathered on GMC use: 1) the resource region model (Bakken 2011), 2) an exponential model based on a declining amount of GMC with distance from the quarry, and 3) a quadratic model that can describe more complex trends such as decrease with distance and variation by direction. The quadratic model was the best fit and highlighted a westward movement of GMC stone tools that was not predicted by the resource region model, nor by the expected declines with distance from the source as predicted by the exponential model.
