Taxonomic list
• Cedar Butte Basalt directly overlies Bed E and was dated at 0.072 +/- 0.014 Ma (whole-rock KA) by Scott et al. 1982; in turn, the underlying basalt of Crystal Springs was dated at 0.210 Ma (KA) by Desborough et al. 1989, as reported by Pinsof 1998
Sangamonian, and overlying B layer is middle Wisconsinan: Pinsof 1991
B layer fauna from Bronco Jim Point and Rainbow Beach is described by McDonald and Anderson 1975 and called the Rainbow Beach fauna by Kurten and Anderson 1980
Carr-Trimble site (Duck Point) is Wisconsinan according to White 1975 and Kurten and Anderson 1980, and therefore records for this site only are excluded
all rodents and lagomorphs reported by Hopkins et al. 1969 were from the Carr-Trimble site
all specimens are ISUM; early collection of Gazin 1935b is not discussed
Bison antiquus is present, but in the B layer only: Pinsof 1991
Pinsof 1998 states that there are "approximately 6,000 specimens" (meaning of vertebrates); of these, he lists 3197 belonging to generically determinate mammals, not including 1771 specifically indeterminate bison specimens
