Fig. 3: Devils Hole water-table record.

Elevation of the paleo water table in Devils Hole relative to today’s water-table position (0 m), based on this study, refs. ¹¹, and ²⁰. The black dashed line is the long-term component of decline discussed in the subsection “Long-term water-table decline component”. Our interpretation of water-table changes across the last 750 kyr (based on refs. ²⁰ and ¹¹) and this study is shown by the blue shading and gray line. Dense blue color means “submerged with high certainty”, white means “not submerged with high certainty” and intermediate colors are a qualitative measure of the likeliness of submergence. They gray line is a spline function showing a likely history of the water table. Intermediate blue shading reflects lack of data, dating uncertainty and the fact that due to the slow growth of mammillary calcite, changes on timescales <10 kyr cannot be resolved. No interpretation of the water table is provided for the oldest part of the record prior to 750 ka due to the scarcity of the data. All age uncertainties are 2σ.
