  • Fig. 1 Comparison of Devils Hole records with other paleoclimate archives.

    (A) 230Th ages with 2σ uncertainties for DHC2-8 (light blue) (23), DHC2-3 (light-mid blue) (23), DH-11 (light green) (7, 8, 23), DH-2 (dark green) (this study), DH2-E (mid-dark blue) (this study), and DH2-D (dark blue) (this study). VPBD, Vienna Pee Dee belemnite standard. (B) δ18O records for samples in (A) [same color codes and references as in (A)] and 65°N July insolation (dark gray) (32). (C) δ13C records for DH-2, DH2-E, and DH2-D [same color codes as in (A)]. (D) Growth rate of samples from this study with [same color codes as in (A)]. (E) Stacked global benthic δ18O records (5). (F) Antarctica CO2 composite curve (3840). (G) 230Th ages on mammillary calcite with 2σ uncertainty (24). Pre-folia, red; post-folia, black; pre-growth hiatus, blue. Arrows indicate the direction of water-table change.

  • Fig. 2 Timing of TII and the last interglacial in speleothem records.

    (A) DH-2 (dark green) (this study) and DH-11 (light green) (7, 8, 23). (B) DH2-D (dark blue) (this study) and DH2-E (mid-blue) (this study). (C) Great Basin composite dripstone record (“Leviathan chronology,” pink) (30); Lehman Cave (red) (26) (dark red) (25); and 65°N July insolation (gray) (32). The midpoints of transitions are indicated with x’s and vertical dashed lines.

  • Fig. 3 TI in Devils Hole and Great Basin paleoclimate records.

    (A) 230Th ages with 2σ uncertainties: DHC2-8 (light blue) (23), DHC2-3 (light-mid blue) (23), DH2-E (mid blue) (this study), and DH2-D (dark blue) (this study). (B) δ18O records for samples in (A) with same color codes and 65°N July insolation (dark gray) (32). (C) δ18O Great Basin composite dripstone record (“Leviathan chronology”) (30) and 65°N July insolation (dark gray) (32).

  • Fig. 4 The age of the TII δ18O midpoint of –15.7 per mil versus depth below the water table [+5.5 m above present elevation (24)] for each sample.

    DH-11 (light green) (7, 8, 23), DH-2 (dark green) (this study), DH2-E (mid blue) (this study), and DH2-D (dark blue) (this study). Uncertainties are 2σ. R2, coefficient of determination.
