What do you guys think? manmade or natural formation?

this formation of rocks is about 15 minutes from my home. No one pays any attention to them or why there even there…..they seem to fit to good to have formed naturally . as far as i know there has never been any professional examination of these rocks. thought i’d get some thoughts before i make a youtube video….
From beginning to end these rocks are piled up on eachother for about 1/4 mile.
people mostly use them for hiking an climbing.

It wouldn’t surprise me if it was a natural formation, i ve seen rocks which are totally uncommon and still the result of mother nature.

This looks natural to me. There are some really strange rock formations in the world that look fake but are natural from erosion and stuff. I went to Wisconsin Dells last year, and there was these big limestone fromations. One in particular was really tall and wide but ended all of a sudden and about 5 feet away from it, there was this big limestone pillar not connected to the other one, but looks like a tower with a platform on top and was about the same height. It looked really cool and the tour we were on, had a dog jump from the top of the cliff onto the "platform" and back. Was really interesting to see. Couldn’t find a picture of it…
