Continuous lake-sediment records of glaciation in the Sierra Nevada between 52,600 and 12,500 C 14 yr B.P.

Abstract

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 for the period 52,600 to 12,500 C 14 yr B.P. A study of the chemistry of the carbonate-free clay-size fraction reported in this paper supports the previous use of total organic carbon and magnetic susceptibility as robust indicators of stade/interstade 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
