Abstract

In the original publication by Quade et al. (2022) textual errors occurred throughout the article. Some of these errors were regrettably made by the authors; others have been mandated by the United States Geological Survey (USGS). The corrected texts are reproduced below; the original article has also been corrected to reflect all changes outlined in this notice. Line 22: Stratigraphic and shoreline evidence shows that floods occurred most frequently from 14.3 to 11.4 ka, followed by lesser events between 14.3 to 11.4 ka, and during the late Holocene from 2.6 to ca. 0.2 ka. Line 197: In the early twentieth century, a canal, the Canada de los Molles, was built across the low drainage divide that diverted the Rio Desaguadero into Salinas del Bebedero (Fig. 2), creating up to a-20 km2 lake. Line 284: U-Pb ages of zircon grains were determined by ablation by a Photon Machines Analyte G2 Excimer laser equipped with a HelEx ablation cell and with a spot diameter of 20 1ìm; samples were analyzed on a Thermo Element2-HR ICPMS (Gehrels et al., 2006; Gehrels and Pecha, 2014). Line 288: For strontium isotope analysis, extracts of waters and mollusks were subjected to clean column elution and thermal ionization mass spectrometry (TIMS) at the US Geological Survey Denver Radiogenic Isotope Laboratory. Line 403: The modeled floods detailed in the Results section and in Supplemental Table 3 and Supplemental Figure 4 looked at the flood volumes, including those of historic floods, that were necessary to simply reach various points downstream up to the area of the Bebedero Basin without filling it. Line 485: Two C. parchappii valves from profile BD-2 (Figs. 3a, b; 4) cut into a high shoreline berm yielded ages at the >35ka limit of 14C dating for carbonates (Table 1; samples BD-2b, f: 40,480 37014C yr BP, 36,310 4014C yr BP). Line 727: LGE-6 is represented by a single channel fill located at BD-31 (400m asl; Fig. 2; Supplementary Figure 3h), where >2m of channel fill cuts into LGE-3 sediments. Line 783: The samples form a linear array (r2 = 0.95) with a slope of about 3.7 that intersects the Global Meteoric Water Line (GMWL) at 18O (VSMOW) = 5.4, close to the value of Beazley tap water (Fig. 6). Line 791: Projection of this data point using a slope of 3.7 back onto the GMWL yields a A18O water (VSMOW) value of 12.8, similar to the composition of rainfall and snow falling at >4000m in the modern eastern Andes (Fig. 6; Rohrmann et al., 2014; Dettinger and Quade, 2015). Line 822: Samples were taken from LHE-1 at site BD-35 along Bebedero Creek, the LGE-2 shoreline complex on the north side of the basin (Fig. 4) that is composed of grusy sand mainly derived from the Sierra de San Luis (BD-2c), and from the R¨ªo Desaguadero (BD-36) 50 km northwest of the basin. Line 825: Samples were taken from LHE-1 at site BD-35 along Bebedero Creek, the LGE-2 shoreline complex on the north side of the basin (Fig. 4) that is composed of grusy sand mainly derived from the Sierra de San Luis (BD-2c), and from the R¨ªo Desaguadero (BD-36) 50 km northwest of the basin. Line 852: Both peaks indicate Andean sources: The former from Permian¨CTriassic plutonic rocks (including the dominant Choiyoi Igneous Complex) exposed in the frontal Cordillera, and the latter from Andean volcanic sources mainly in the western Cordillera of the Andes. Line 975: This temperature range yields an estimated 18O water VSMOW value of 13 1.5 (Fig. 8) using 18Oshell VPDB = 12.3. Line 1026: H. parchappii is a small (3¨C5 mm) hydrobiid (Fig. 3d) that is generally adapted to fresh water but tolerate a wide range of salinities up to 23%, such as is found in evaporative lakes and river estuaries (Prieto et al., 2004; De Francesco and Hassan, 2009). Line 1114: The channel fills are locally composed of shell coquinas dominated by B. peregrina, indicating fresh, lentic, oligotrophic host water. Line 1249: In Patagonia, numerous moraine-dammed lakes were formed by the advance of glaciers during the Little Ice Age, followed by recent recession (Anacona et al., 2015;Wilson et al., 2018). Line 1282: Many avalanches are triggered seismically (e.g., Ferrer, 1999), but historically large rainfall events causing slope failure seem to be the primary cause for avalanches (Moreiras, 2005). Line 1294: The lake began to rise dramatically starting 18-17 ka and reached its hydrologic maximumbetween 16.4 ka and 14.1 ka, when the lake covered 55,000 km2 (Placzek et al, 2006). Line 1438: This may explain why the chronology of late glacial flooding at Bebedero closely matches the periods of megalake development and wetland expansion in the subtropical latitudes of Chilean Atacama Desert and Bolivian Altiplano. Additionally, the original article contains an error in figure 8. The correct figure 8 and caption is reproduced below: Per the USGS, the acknowledgments section has been corrected to read as below.
