Figures & data
FIGURE 1. Location of Sawtooth Lake and other sites referred to in text. Bathymetric map and location of the sediment cores
FIGURE 2. Concentration of (a) diatoms and (b) chrysophyte cysts within core 10–5. Diatoms are absent below 6 cm. The gray band marks the presence of a turbidite
FIGURE 3. Percentage diagram for Sawtooth Lake diatoms and their concentration within the sediments. Sum of other benthic taxa includes Achnanthes, Denticula, Diploneis, Hannaea, Navicula, and Nitzschia as well as other less well-represented genera such as Caloneis, Cocconeis, Cymbella, Diatoma, and Pinnularia. (See for taxa list.) The gray band marks the presence of a turbidite
