The plot thickens in Ohio

There is enough controversy about the origin of these pockmarks in Ohio that they could be karst depressions made by melting permafrost, or they could be kettles made by isolated ice boulders that melted and left a hole in the ground. But there is the more esoteric possibility that they are craters made by impacts of glacier ice boulders launched by an extraterrestrial impact on an ice sheet. And there are victims to prove it.
