Location of NAHS Sample Sites

Figure 1: Map displaying synthesis site locations and proxy types.  Blue circles are oxygen (δ¹⁸O) and carbon (δ¹³C) stable isotope data, yellow stars are lake sediment chemistry data (% carbonate, Mg/Ca, gypsum abundance, loss-on-ignition-based bulk geochemistry), purple triangles are lake elevation (tracking shoreline migrations in sediment cores, dating of highstand and lowstand benchmarks), light green trapezoids are peat indicator data (plant macrofossils, n-alkanes), dark green X’s are pollen-based vegetation data, gray squares are productivity indicators (diatom assemblages, moss production), red diamonds are terrigenous input indicators (grain size, % sand, Ti, Al₂O₃, mineral mass accumulation rate), and orange crosses are testate amoebae-inferred water depth.
