Show sedimentation of the lake. I propose that this transformation results from the diversion of the Bear River ( the largest tributary to the GSL) into the Great Salt Lake Basin, following the deposition of an extensive lava dam in the Thatcher Basin of southern Idaho ( Bright, 1967). The sedimentary change occurs ca. 310 Ka, near the transition isotope state 8 to 9. It did not permanently increase water depth, but appears to have increased the magnitude of the pluvial - interpluvial oscillations. LITERATURE CITED Axelrod, D. I., 1957.
