Wisconsin's Henry S Reuss Ice Age Visitor Center: Kettle Moraine State Forest Northern Headquarters
The Wisconsin Department of Natural Resources (DNR) fits the Nebraskan glaciation with Nebraska state 300,000 to 260,000 years ago.
The DNR gives the best-preserved deposits and landforms as -- of course -- Nebraska even as it guides us to the Nebraska-neighborly, Nebraska-surrounding states.
So would that be all or some states from neighboring South Dakota, Iowa, Missouri, Kansas, Colorado, and Wyoming?
