Uranium-series age estimates and paleoclimatic significance of Pleistocene tufas from the Lahontan basin, California and Nevada

An extended chronology of Lahontan basin lake levels based on uranium-series age estimates correlates with the global ice-volume record. Lake highstands occur at or shortly after times of maximum ice-sheet size. Moderate size lakes occur when the global ice volume is about 80% of its maximum. The data indicate that lake levels rise and fall relative to the proximity of the mean position of the jetstream. When the continental ice sheet is above some threshold size or shape, it appears that the large-scale circulation and climatic conditions are right for producing lakes of moderate to large size within the Lahontan basin. ?? 1988.

Lake-size variations in the Lahontan and Bonneville basins between 13,000 and 9000 14C yr B.P

Recessions of Lakes Lahontan and Bonneville that commenced ∼13,500 14 C yr B.P. were interrupted at ⪖11,500 14 C yr B.P. in the Lahontan basin and ∼12,200 14 C yr B.P. in the Bonneville basin by relatively large perturbations in lake level that persisted for ∼ 2000 years. Minor glacial readvances in the Sierra Nevada and White Mountains of California-Nevada occurred during the latter half of this interval (between 11,000 and 9700 14 C yr B.P.). The hydrologic response of Lakes Lahontan and Bonneville and the mountain glacial advances were concurrent with the Allerød/Younger Dryas climatic intervals recorded in vegetational and glacial records of western and central Europe.
