   "abstract": "A context for recent hydroclimatic extremes and variability is provided by a \u223c10 k.y. sediment carbonate oxygen isotope (\u03b418O) record at 5\u2013100 yr resolution from Bison Lake, 3255 m above sea level, in northwestern Colorado (United States). Winter precipitation is the primary water source for the alpine headwater lake in the Upper Colorado River Basin and lake water \u03b418O measurements reflect seasonal variations in precipitation \u03b418O. Holocene lake water \u03b418O variations are inferred from endogenic sedimentary calcite \u03b418O based on comparisons with historic watershed discharge records and tree-ring reconstructions. Drought periods (i.e., drier winters and/or a more rain-dominated seasonal precipitation balance) generally correspond with higher calcite \u03b418O values, and vice-versa. Early to middle Holocene \u03b418O values are higher, implying a rain-dominated seasonal precipitation balance. Lower, more variable \u03b418O values after ca. 3500 yr ago indicate a snow-dominated but more seasonally variable precipitation balance. The middle to late Holocene \u03b418O record corresponds with records of El Ni\u00f1o Southern Oscillation intensification that supports a teleconnection between Rocky Mountain climate and North Pacific sea-surface temperatures at decade to century time scales.",
