When built mill used a huge overshot wheel in basement, but was soon replaced by the more efficient turbine. This mill has been very well maintained by the state, along with the park camping grounds and is well worth the time to go through. It has been open to visitors on Sundays through the summer months.
Will try to get some interior shots this summer and send in. Wild Cats Den State Parks is east of Muscatine and can be reached from either highways 22 or 61.
