interpretation
1

basis: The d18O record from the varved sediment from Crevice Lake is a proxy for hydroclimate, particularly discharge of the Yellowstone River, in Yellowstone National Park. Low d18O values are consistent with high flow of the Yellowstone River and, thus, wet winters with deep snow pack. They also correspond in general with tree-ring inferred estimates of increased precipitation in the YNP region. Prior to 2000 cal BP, decreasing d18O values suggest an increasingly wet climate or a gradual shift to winterdominated precipitation

basis: Comparison of the oxygen-isotopic record with independent measures of climate suggests that the annual moisture balance is the primary isotopic control, with the seasonal timing of precipitation providing a possible secondary influence. High d18O values are associated with dry climate (e.g., evaporative enrichment of 18O) and/or wet summers relative to winters (higher d18O values of atmospheric precipitation).
