| Glaciers descended the eastern flanks of the Sawtooth Mountains repeatedly during late Pleistocene time, constructing an extensive moraine belt at the range front in the Sawtooth Valley. The glacial sequence and the numerous lakes it hosts preserve a detailed record of those fluctuations, themselves a reflection of complex climatic processes during the last glaciation. In particular, we infer that the chronology derived to date reflects strong influences of Pacific moisture delivery on the alpine glacial system. |
