In support of paleoclimatology investigations, samples of mammillary calcite, calcitic folia, and flowstone were collected by the U.S. Geological Survey in Devils Hole and Devils Hole Cave 2, Nevada, between 1983 and 1996. These samples came from about 60 m below to 9 m above the modern water table in these caverns. To determine δ18O and δ13C time series spanning the interval 567.7–4.5 ka, more than a thousand samples were milled and analyzed for their δ18O and δ13C values. To determine time-series ages, more than a hundred samples were analyzed using uranium-series dating. Many of these measurement results have not been published. Herein, we provide previously unpublished δ13C and δ18O values, and we provide unpublished...

The mid-to-late Pleistocene Devils Hole δ18O record has been extended from 60,000 to 4500 yr ago. The new δ18O time series, in conjunction with the one previously published, is shown to be a proxy of Pacific Ocean sea surface temperature (SST) off the coast of California. During marine oxygen isotope stages (MIS) 2 and 6, the Devil Hole and SST time series exhibit a steady warming that began 5000 to > 10,000 yr prior to the last and penultimate deglaciations. Several possible proximate causes for this early warming are evaluated. The magnitude of the peak δ18O or SST during the last interglacial (LIG) is significantly greater (1 per mill and 2 to 3°C, respectively) than the peak value of these parameters for the...

Fig. 29. Four-inch (10-cm)-diameter core hole of DH-11 in vein calcite on hanging wall about 100 ft (30 m) below water surface in Devils Hole. Note that there is little to no accumulation of sediment on, and thus little to no incorporation of sediment into, this overhanging surface. 1987.

This U.S. Geological Survey (USGS) data release consists of a spreadsheet presenting high-frequency water levels in feet below a measuring point (MP) at Devils Hole in Nye County, Nevada. Water-level data are collected at USGS site 362532116172701 by the National Park Service, using a data logger programmed to collect water-level every 15 minutes or every 5 seconds when a water-level change greater than 0.015 feet is detected. Data are analyzed, approved, and audited according to USGS standards as described in U.S. Geological Survey Office of Surface Water memo 2017.10. Continuous 15-minute data are published in the National Water Information System (NWIS) database. Irregular periods of 5-second data collected during...

Fig. 6. View looking up from Anvil Rock (immediately above D in Fig. 4) in main chamber of Devils Hole at about 80 ft (24.4 m) below water surface. The planar fissure strikes NE and dips 70–80 degrees to SE. Widths of the fissure typically range < 6.5 ft ( <2 m). White translucent mammillary calcite coats hanging wall (left in photo) of Paleozoic carbonate bedrock. Footwall (right in photo) is barely visible in the narrow fissure.

This data release documents a modified version of the Death Valley version 3 steady-state (DV3-SS) model described in U.S. Geological Survey Professional Paper 1863 (https://doi.org/10.3133/pp1863). The DV3-SS model was modified by conversion into a superposition model with initial heads of 0 ft (0 m). Simulated water-level changes are relative to modern, predevelopment (pre-1950) conditions, where modern levels have a reference datum of 0 ft (0 m). The modified DV3-SS model is a three-dimensional, groundwater model (MODFLOW-2005) that was used to estimate paleo-recharge in the Ash Meadows groundwater basin, southwest Nevada, using the Devils Hole (cave 2) water-table record that spans the last 350,000 years.
