Abstract
Pluvial-lake highstands in the Bonneville basin are known to be contemporaneous with periods of Quaternary glaciation. At least five lake cycles have been identified from prior studies of two deep cores (Eardley and Gvosdetsky, 1960; Eardley and others, 1973) and several isolated outcrops in the main part of the Bonneville basin and eastward in Cache Valley. These are the Lava Creek B (~620 ka, marine isotope stage MIS 16), Pokes Point (~420 ka, MIS12), Little Valley (~150 ka, MIS 6), Cutler Dam (~60 ka, MIS 4), and Bonneville (~18 ka, MIS 2) lake cycles (Oviatt and others ,1987, 1999; Lisiecki and Raymo, 2005). Cache Valley, straddling the Utah-Idaho border, held the northeastern arm of Lake Bonneville, and is the entry point of the Bear River, the largest river to supply water into the basin. This river did not fully enter the Bonneville basin until ~55 ka (Pederson and others, 2016).
