Wouldn't the better Q be how could it NOT be natural?

Sorry, natural erosion.

That’s a sedimentary rock. Layers were laid down over time and it turned to stone. It’s either sandstone or limestone.
Sugar Cr flows through Turkey Run State Park and it’s a beautiful waterway. I grew up near there and have been there many times.
