another mystery of nature

This summer, our yard in wisconsin got decimated as shown. Overnight, something ripped up the sod, and left no tracks we could find. At first we thought feral pigs, which are beginning to spread in Wisconsin, but they would have left tracks. Neighbor says they suspect skunks going after grubs, but damn, I don't want to get sprayed by the behemoth that left this carnage.

The impatiens that ate Cincinatti

Not sure what mutation transpired in the back yard here, but we have this hulking Impatiens towering over the normal sized ones in this pot. Anyone ever seen this happen before?
