    About 16 years ago I climbed to the mounds with my 3 year old and my 10 year old sons. I am in the habit of carrying a walking stick. If I don't bring one I pick one up and my boys usually copied me. This time was no different. We walked past the initial mounds with no incident. Walked out to the end of the group of mounds. As the sun was beginning to set we turned back. As we were about to walk past that first set of mounds, my 3 year old stopped and turned to the mounds as if someone called him. He then slowly and reverently walked over to the mound holding his walking stick at arms length. He bent over and placed his stick on the ground at the mounds feet. Stood erect with his head bowed for a few seconds and then turned and walked away. Now being a 3 year old we had not bothered to explain to him what the mounds meant but his actions sure seemed like someone did. I never saw anything up there but I sure think something called to my boy.

    Visited the mounds and had some eerie feelings of being watched while there. Not necessarily good nor bad - just watched. I also stopped a few times and it seemed strangely silent, too. I could only hear maybe one bird tweet in this vast land around me. But nothing else stirring. Like, too quiet. After having been in two different nearby state parks, where you normally hear lots of natural noises, this was pretty silent. Also, many of the trees here seem like they must have been in more than a few pretty violent storms over the years. Many were mangled and stripped bare.

    I’ve hiked here many, many times and had one incident in particular I could not figure out. This happened in early April of 2020 I believe. There were some snowy spots yet and it was a little cold so my daughter and I had the park to ourselves. Walking uphill in the entrance we heard the loudest most anguished scream. Now maybe there is an explanation for that part, but just afterwards we heard what sounded like a horse (grunting?) right between us. This was the only time we have had something strange happen here. We just cant figure out what made that day different.
