英文摘要	Dry lakes are common environmental matrixes of hydrographically closed (endorheic) valleys in western North America's deserts. Groundwater discharge localities that form in arid regions are excellent data sources, recording hydrological responses to regional and global climate changes. This research brings geomorphic, geochemical, and stratigraphic evidence from a paleo-age groundwater discharge locality in the Eldorado Valley of extreme southern Nevada, U.S.A. Sediments and stratigraphy suggest that a dynamic groundwater discharge complex formed in response to wet and dry climate cycling within the Eldorado Valley. This groundwater discharge locality was likely present on an annual to decadal scale, fed by groundwater rather than river sources, justifying the higher metal concentrations in deeper sediment layers. The C-14 dating further indicate this system was actively cycling between 13.9 and 4.88 ka cal yrs BP. Thermal regimes of warm-seasonal precipitation anomalies during the late Pleistocene to Holocene provided ideal conditions for a dynamic ecosystem due to a groundwater discharge locality located at the Eldorado Dry Playa.
