ABSTRACT: Samples from 107 piņon pines (Pinus edulis) at four sites were used to develop a proxy record of annual (June-June) precipitation spanning the AD 1226-2001 interval for the Uinta Basin Watershed of northeastern Utah. The reconstruction reveals significant precipitation variability at interannual to decadal scales. Single-year dry events before the instrumental period tended to be more severe than those after 1900. In general, decadal-scale dry events were longer and more severe prior to 1900. In particular, dry events in the late 13th, 16th and 18th Centuries surpass the magnitude and duration of droughts seen in the Uinta Basin after 1900. The last four decades of the 20th Century also represent one of the wettest periods in the reconstruction. The proxy record indicates that the instrumental record (~1900-Present) underestimates the potential frequency and severity of severe, sustained droughts in this area, while over representing the prominence of wet episodes.
