Walker Lake, a terminal desertic lake in Mineral County, Nevada, has fluctuated greatly in the lake level throughout its long history. In its Late Pleistocene high stand, Walker Lake formed the southernmost embayment of pluvial Lake Lahontan. Studies of tufa morphology and stable isotope character, closely integrated with sedimentologic data, show great promise for elucidating the post-glacial climate history of the Great Basin. Our results indicate the late Pleistene low stands below 1222 m circa 18 000 yrs BP, a post-Pleistocene period of desiccation during which alluvial fans formed, another rise to 1250 m, another period of desiccation circa 2000 yrs BP, a rise to the historic high stand of 1244 m and, since 1880, a drop to 1206 m. -from Authors
