I was seeing the same thing as Bill Cody and some of the above, any place where there was a protrusion thru the ice, that wound up letting water up thru the ice wound up in a huge, 50' plus diameter of water logged snow around the perimeter of whatever protrusion created the hole, the weird part was, even after some really cold weather for several nights, the slush only crusted over and there was still a wet, soft layer between the original ice and the surface which had obviously crusted over but to me should have been frozen solid after several single digit days.
