Then an ice saw is used to cut the circle. This can kind of can be seen on the last few pics with how the ice has piles of cut ice all around the perimeter. Then as the ice melts you get round ice slabs. This is all similar to crop circles. Some call it art, other call it alien phenomena, and then there are those that call it a waste of time. Neat looking though.
