In the summer of 1999, glacier-dammed Iceberg Lake drained catastrophically and completely, exposing to subaerial erosion a lacustrine sediment package that records over 1500 years of continuous deposition. Situated in southcentral Alaska at the heart of the world's largest nonpolar icefields, this record offered an unprecedented opportunity to characterize at high resolution the history of climate and glacier response for a remote, understudied region previously known only by a 50 year historic/instrumental record, 500+ years of tree rings, and patchy records of late Holocene glacier advances. Combining Iceberg Lake's unique and well-exposed stratigraphic record with additional evidence that includes results from a newly developed [...]
