Glacial geomorphology and chronology of the (a) Lago Palena/General Vintter ice lobe with ¹⁰Be ages (n = 4) obtained from the innermost moraine ridge (PV6) and (b) the Cerro Riñón valley glacier with ¹⁰Be ages (n = 26) obtained from CR1-CR5 moraine complexes and the additional perched boulder. On top of the boxes the mean moraine age is acompanied by 1 standard deviation (σ) and the Standard Error of the Mean (SEM) including a 3% propagated production rate error²⁰ (Table 1). Individual ages are presented along with internal uncertainty and sample ID. One age in red italics is considered an outlier. Inset maps with the location of sites mentioned in the text. Black dots correspond with glacial chronologies from RG: Río Guanaco; SUE: Seno Última Esperanza. Red dots correspond to paleovegetation reconstruction. LL: Lago Lepué. CP: Canal de la Puntilla. HM: Huelmo mire. Green dot is the location of ODP1233 sediments core. White outlines represent Northern (NPI) and Southern (SPI) Patagonian Icefields and Cordillera Darwin Icefield (CDI).
