I'm surprised no one mentioned Pumapunku in Bolivia or other ancient structures. The stone work would be mind blowing if it was done this year, but it's thousands of years old. I saw a dude walk around with a speed square and every 90 was perfect, inside 90's too! The precision is basically impossible for us to match, for now at least. Fossils hung around, so where's the remnant tools used to make stuff like Pumapunku?
I got a friend from Peru who goes home once a year. Last time he said he was going to see the Nazca Lines. I asked him to bring me a rock. He brought one from near by. He said they watch everyone like a hawk.
There's several Pyramids in the yoo ess. One in Arkansas.
The video -> definitely a piece of ice that is rotating in the water as it melts
Ice that can disappear at random and travel 1 kilometer in distance in less than 10 seconds? I had a topographical map and watched it appear on the far side of the lake and dash over towards the side I filmed from. That's when I started to roll the camera. Here have another look http://youtu.be/CXRxhWKziq8
