Abstract
Red tills deposited by post-Twocreekan (Valderan) ice advances of the Green Bay and Lake Michigan Lobes in eastern Wisconsin do not extend to the type locality of the Valders till. The post-Twocreekan ice of the Lake Michigan Lobe terminated at the Two Rivers Moraine, 30 km northeast of Valders. Likewise, geomorphic criteria and depth of carbonate leaching indicate that post-Twocreekan ice of the Green Bay Lobe did not reach Valders from the west.
