ABSTRACT Reconstructing the drainage from glacial Lake Agassiz to explain episodes of abrupt climate change during the last glacial termination has a long and colorful past. The type strandlines in the basin are named for the towns of Herman, Norcross, Tintah, and Campbell. Optically stimulated luminescence dating of these and other strandlines from the southern basin of Lake Agassiz enables estimating times of water level stability and outlet incision. Tracing strandlines to the north is complicated by their increasing number and often discontinuous nature. Much of the meltwater entering the Mississippi River was channelized through Lake Agassiz’s southern outlet. The spillway is floored by boulder lags and bedrock. Two cores penetrating through to bedrock have provided the most detailed history of southerly lake drainage. On the first day of the trip, we will travel to strandlines on both sides of the southernmost Agassiz basin and view the glaciolacustrine stratigraphy at Fargo, North Dakota; on the second day, we will visit more strandlines and the southern outlet spillway.
