I went to Ha Ha Tonka State Park in the late fall of 1996. I don't remember where I had heard about it, but it looked like it would be quite interesting. As I recall, the drive from Columbia was at least two hours; probably more. But it was well worth it, and I remember the day almost as if it were yesterday. I highly recommend a visit, but if you can't make it, more information is available in the
Landmarks I've Visited section.

One of the main walls left standing after the mansion was destroyed by fire.
Sunlight coming through the window looks like fire.

More ruins, including the archway.
A window through a window.
More mansion.
