A sandstone arch about ninety feet across in the Shawnee National Forest, cut by a creek that found a weakness and went through the rock rather than around it. A short trail drops off the ridge to it and you can walk over the top. It is the kind of thing that would have a visitor centre in a western state and here has a gravel car park.
That was 1 of the hidden places.
