Visitor Tips and News About Mystery Hill
Mystery Hill is another Mystery Spot where gravity is defied and water runs uphill. It's been there since at least the 1950's...[Ed Gallagher, 05/29/2006]
Besides Prehistoric Forest, which was sold, but has remained in operation, is "Mystery Hill" about a half mile east of Prehistoric Forest on U.S. 12; a Paul Bunyan statue at Stagecoach Stop U.S.A., a wild west theme park a couple of miles further east; a derby-wearing cow on top of the Golden Nugget Saloon, across the road from Paul Bunyan; President Eisenhower's official Presidential train car at Stagecoach Stop; a very unique Catholic Shrine at St. Joseph Catholic Church, west on U.S. 12. This shrine was built of concrete resembling wood, stone, rope, thatch and other natural materials. It was built by mexican artisans during the thirties. Also nearby are the twin "Irish Hills Towers" a pair of observation towers at the highest point in the Irish Hills. There is also a neat little drive-in that is now closed, but it is still standing: "The Sauk Trail Chuckwagon". This is built to look like a covered wagon. The Irish Hills are located about sixty miles west of Detroit on U.S. 12 on the way to Chicago.[Rob Burg, 04/05/1998]
