  1. I have been to this location several times.With my experience, there is an ominous feeling at the top and side of the mounds.I have always had the feeling of being watched by something unseen.

  2. I was driving back to Pontoon Beach from St Louis one summer night on business and a major storm was rolling in. The wind was whipping like crazy and there were bolts of lightening in every direction. I was on my trusty GPS navigator, as I wasn’t too familiar with the area. My GPS told me to exit about 5 exits before I was supposed to and it took me directly to the middle of this Cahokia State park and dropped me there. The sky was an eerie green and I felt like my little car was going to get blown away at any second. I knew this area wasn’t in the safest neighborhood, so I was freaking out. Luckily my navigation picked back up its signal and got me to where I actually needed to go, but driving through this ominous area during a raging storm was one of the most terrifying things I’ve ever encountered. The feeling of spiritual activity and existence was intense.

  3. When I was a little girl I spent a lot of time there as a kid. I would ride my bike there with my friend and there were cold spots all over. I had no idea that was paranormal as a child but I felt them all the time.
