We actually have a pretty hefty amount of werewolf lore from Wisconsin. One mainly being The Beast of Bray Road.
The funny thing about the maps part (with the main animal effigy mound clusters) is that in Demonic Ceremonial Magic, you actually have to kill the animals and use the pelt as a mean of shapeshifting. In fact, Wisconsin has the most werewolf sightings anywhere in the U.S.
