Abstract

A 2200-yr long, high-resolution record of drought variability in northwest Montana is inferred from diatoms and δO 18 values of bio-induced carbonate preserved in a varved lacustrine core from Foy Lake. A previously developed model of the diatom response to lake-level fluctuations is used to constrain estimates of paleolake levels derived from the diatom data. Spectral analysis of the δO 18 data indicates that severe droughts occurred with multi-decadal (50 to 70 yr) frequency
