Lampropeltis calligaster — Prairie Kingsnake
Something was seriously wrong with this snake's head. It was noticeably asymmetrical from the front, and just generally the wrong shape. Also the snake's jaw didn't close properly and it had some kind of crud on its face. It's possible this snake was a victim of the dreaded Snake Fungal Disease, though its body seemed to be in good shape and it moved fairly normally other than the way it held its head.
