The dataset comprises of X ray fluorescence log ratio time series data for two sediment cores from Lago Pato, a small lake basin at 51.3003 S, 72.6786 W and approx 33 m a.s.l., which is topographically separated from Lago del Toro in Torres del Paine (TdP). The data are used to constrain glacier dynamics and lake level change in the TdP and Ultima Esperanza region over the last approx 30,000 cal a BP (30 ka). LP08 was extracted from the current depocentre in November 2007 to March 2008. LP16 was extracted the terrestrial shoreline in November 2015.
