Paleo-hydrologic surface deposits signify wetter than present conditions during the Last Glacial Maximum (LGM) in the American Southwest. Detailed knowledge exists about the location of these surface deposits, as well as the climate and hydrologic conditions during the LGM. Using groundwater modeling programs in conjunction with paleohydrologic deposits allowed for an opportunity to quantitatively characterize past climate for a 100,000 km2 area near Death Valley, approximating recharge and the level of the potentiometric surface. Simulations using the Death Valley Regional Flow System model indicated that the average recharge rate in the model domain during the LGM was approximately 1.63 cm/yr, or 7.71 times the calibrated modern recharge rate. As a result, the simulated potentiometric surface was generally 0-50m higher throughout the model domain. Assuming LGM precipitation was twice the modern value (Forester et al., 1999), ~6.80% of total precipitation became recharge during the LGM, compared to only ~1.75% during modern day.
