description: carbonate
basis: The middle to late Holocene d18O record corresponds with records of El Nii¿½o Southern Oscillation intensification that supports a teleconnection between Rocky Mountain climate and North Pacific sea-surface temperatures at decade to century time scales.

basis: Drought periods (i.e., drier winters and/or a more rain-dominated seasonal precipitation balance) generally correspond with higher calcite d18O values, and vice-versa;although lake-water values are currently observed to change through the ice-free season from ?16.7? to ?13.5? (n= 10), the late summer values are artificially elevated (inset of Fig. 3.).The lower, early summer values are similar to average weightedprecipitation-?18O, and similar to values inferred from near-surface calcite-?18O prior to 1953 (see Fig. 3 in Anderson, 2011). It is on this basis that variations in through-flowing Bison Lake water-?18O are interpreted as precipitation-?18O and changes in the ratio of the seasonal precipitation balance between snowfall-dominated ?18O) and rainfall-dominated (higher ?18O).
