Watch this animated graphic to see the data come together. The moving average trendline derived from the SPD (white line) is overlaying generalized paleoenvironmental data (Wong et al. 2015); yellow indicates warming/drying, blue (3000-1000 cal BP) indicates cooler, wetter climate, and the dashed red boundary line indicates that a short dry period occurred sometime in range. Brackets with bison dates indicate bison presence occurring sometime within that range, not spanning the entire period (that we know of). The start of earth oven plant baking is given as modeled date range, with the start occuring sometime within that range.
