The AA. compare proxy records of alpine glaciation obtained from sediment cores in the Owens and pyramid lake basins of California and Nevada in order to define the centennial- to millennial-scale glaciation history of the Sierra Nevada
oscillations in the Owens Lake basin. Such records are critical in assessing the relation (if any) of North Atlantic temperature pertubations (Dansgaard-Oeschger cycles) to climate variability in the Western United States.
Lake occurred during Heinrich events H1, H2, and H4. These results enforce the concept that relatively dry-wet oscillations in the climate of the Great Basin of the western United States occurred at approximately the same times as cold-warm oscillations
