Fig. 2: Devils Hole 2 (DH2) δ18O, δ13C, and palaeo water table elevation over the last 600 ka.
From: Controls on the southwest USA hydroclimate over the last six glacial-interglacial cycles

From top: DH2 δ18O and δ13C (11; this study). Blue lines indicate core-P δ18O data spliced into core D record (see text). Blue diamonds indicate palaeo water table elevations in DH2 cave relative to modern, including 2σ age uncertainties27,28. Purple shading is produced from a binomial spline of DH2 water table data.
