An account in Crawford County, Missouri

I was fishing at the Riverview Access conservation area near Cuba MO off of state rd O. I had been fishing for a couple hours. I was the only one there. The sun had gone down and it was starting to get dark. It was right around 8:30. I witnessed a large rock come from the tree line on the opposite bank and land in the water. It made a big splash. The rock itself was quite large and flew through the air every bit of 20 feet from the point where I first saw it. I am 6’3 350 lbs. a strong guy. But I could not throw a rock that large anywhere near that far. I never saw whatever or whoever threw it. All I know is that something caused that rock to fly through the air. I instantly was confused and fascinated. I stood there for a minute thinking I would be able to see something move in the trees. I didn’t and thought it was a good idea to leave.
