Geomorphology, stratigraphy and chronology of Pleistocene Lake Bonneville deposits, with emphasis on the Provo shoreline, Bonneville basin, Utah

Much is known about the general history of Pleistocene Lake Bonneville and its deposits in the Basin and Range province of the western United States. However, few studies have examined the smaller-scale oscillations of the lake and the precise timing of the lake's climate-driven regression from the Provo shoreline. This study focuses on the sedimentology, stratigraphy, geomorphology and chronology of deposits associated with the Provo shoreline in order to refine the timing of the lake's drawdown and examine the possibility of one or more mid-Provo age regressions. Major and minor shoreline features and nearshore to offshore deposits are analyzed in detail for the Provo-level history and correlated across the Bonneville basin. The results of this study hold important implications for refining the record of lake level changes in the Bonneville basin and for correlation to regional and global records of climate change.
