Pollen analysis of a Late-Glacial and Holocene sediment core from Mono Lake, Mono County, California

Auteur :
DAVIS, O.K.

Description :
Pollen analysis of a 752-cm core from Mono Lake, California, indicates generally high lake levels 11,600-7000 C 14 yr B.P., moderate lake levels until ca. 4000 C 14 yr B.P., and fluctuating levels to the present. Drying events, with lake levels near or below the historic minimum are dated ca. 8800, 4000, 2400, and 1100 C 14 yr B.P.. Chronologic control is provided by 6 radiocarbon dates and 6 volcanic ashes. The pollen-based reconstructions of climate are generally cooler and wetter than today, with relatively dry but cool climate during the early Holocene.
