Sediment cores recovered from an alpine bog (3100 m) trapped behind a Pinedale age moraine, ∼2 km downvalley from a high-elevation cirque, reached glacial-age debris and recovered ∼6 m of lake clays overlain by gyttja. Accelerator mass spectrometry dating, sedimentology, variations in magnetic properties, and organic carbon data reveal six distinct periods of glacial and/or periglacial activity. These include a late Pleistocene Pinedale glacial termination just before 12 120 14C yr B.P., a Younger Dryas chron cirque glaciation, an early Neoglacial periglacial event (ca. 4900 14C yr B.P.), a late Holocene cirque glaciation (3700 14C yr B.P.), as well as late Holocene periglacial events at 2800 14C yr B.P. and the Little Ice Age (ca. 120 14C yr B.P.). Cold events in the middle to late Holocene correlate with subtle ice-rafting events in the North Atlantic and records of cold events in North America and Europe and were probably hemispheric in extent.
