L. R. Follmer, R. C. Berg, J. M. Masters

Research output: Contribution to journalArticlepeer-review


At this site (Simpson Road Sand and Gravel Pit, Winnebago County) we will view an exposure of many ice wedges that have developed in the sand and gravel of the Rockford Terrace. Because the Argyle Till underlies the terrace deposits and the Sangamon Soil has formed into its surface, the Rockford Terrace probably was deposited by meltwater from the glacier that deposited the Argyle. -from Authors
