We happened upon this state park and it is a very neat place to stay for the night. There are some of the most unusual formations in the park. The siltstone and clay shale have made cracks or "caves" into the sides of the cliffs. They go back into the cliff and you feel like you are in a cave but the top is open. It is cool in them. If you ever are in this area, do stop and check them out. We camped here in a Motorhome.
