Las Vegas Valley stratigraphy compared to Greenland ice core climate record

Detailed Description

Types of groundwater discharge in the Las Vegas Valley compared to isotopic values from the Greenland ice core record (higher isotopic values to the right represent warmer conditions; lower values represent cooler conditions). Wetland expansion and contraction in the Las Vegas Valley marched in virtual lockstep with short-lived, northern hemispheric climate oscillations, including Dansgaard-Oeschger (D-O) cycles, the Bølling (B) and Allerød (A) warm periods, and the Younger Dryas cold event (YD).
