Analyses of calcium carbonate \r\nand organic matter concentration, magnetic susceptibility, \r\ntitanium content, dry bulk density, and macrofossils are used \r\nto reconstruct water-level changes. The development of sand layers \r\nand deformed sediments at the deep-water core site (i.e. Core A-06) \r\nprior to ~10,900 cal yr BP suggest that lake level was lower at \r\nthis time. Fine-grained organic sediment deposited from 10,600 \r\nto 9,500 cal yr BP indicates a rise in lake level. The formation \r\nof an unconformity at the shallow cores site (Core C-06) and the \r\ndeposition of shallow-water calcium carbonate-rich facies at the \r\nCore A-06 site between ~9,500 and ~8,500 cal yr BP suggest lower \r\nlake levels at this time. Shallow-water facies gradually transition \r\ninto a sand layer that likely represents shoreline reworking during \r\nan extreme lowstand that occurred at ~8,400 cal yr BP. Following \r\nthis low water level, fine-grained organic-rich sediment formed \r\nby ~8,200 cal yr BP, suggesting deeper water conditions at core \r\nsite A-06. Calcium carbonate concentrations are relatively low \r\nin sediment deposited from ~6,300 to 3,100 cal yr BP in Core A-06, \r\nindicating that lake level was comparatively higher during the \r\nmiddle and late Holocene. In general, results from this study \r\nsuggest that the early Holocene was characterized by high P/E \r\nfrom ~10,500 to 9,500 cal yr BP, low P/E from ~9,500 to 8,400 \r\ncal yr BP, and return to higher P/E from ~8,200 to 3,100 cal yr BP.  \r\n\r\n","author":null,"citation":"Pompeani, D.P., B.A. Steinman, and M.B.
