Here is a link to the Scuppernong Springs Self-Guided Nature Trail brochure Scuppernong Springs Nature Trail Brochure. It includes a map of the Nature Trail (shown below) and a description of the highlights you will see along the way.
Here are two maps of the buildings comprising the Old Hotel/Cheese Factory/Mill site. Ron Kurowski, from the Kettle Moraine Natural History Association, supplied them to Robert Duerwachter for use in his excellent book THE PONDS OF THE SCUPPERNONG.
He zoomed in to get these three pics (Thanks Ben!)
Check out this view of the area courtesy of Google Maps. You can use the Marl Pits to help orient yourself.
Also, check out the Wisconsin Wetlands Association (WWA) Wetland Gems Page SE-10 Scuppernong River Area for a nice overview.
