We seem to be having a little ’90s resurgence, based mainly on the number of girls I’ve seen wearing high-waisted shorts over tights, and also the fact that they put Beavis and Butt-Head back on TV. So I guess the hip aliens are going back to making mysterious circles, like they used to do in the days before Fortean Times had a website. But this time, instead of decorating the fields of England, they’re punching weird spinning disks out of river ice.

Best guess on what’s actually happening here: An eddy in the river sets up the spinning motion, and it’s the spinning itself that causes the ice disks to be so perfectly circular. Second best guess: Definitely aliens.
