I grew up on the Prairie center before it was a state park. The land was owned by Mr. Schanze, who my parents bought their house and land from. I am not quite sure but I believe it was passed down in his family. I will see if I can find out more when I talk to my parents next. The was a tragic story tied to him that I will not post publicly. I know that park well. Such good memories. It was almost magical.
I’ve wondered the same thing!
I don't know the answer to your question, but I do know there were other structures there in the past. That would be a question for one of the guides. They would know the answer. Sorry I couldn't be of more help.
