On Dirty Jobs tonight, Mike Rowe was helping an Big Animal Veteranarian. What was that critter? It looks like it could have been a wolverine or fisher but it had a very pointed snout like a possum has. Big white whiskers. I can't describe it well, but I've been ruling things out with my biologist sister and Googling it. The key is the sharp pointed snout - completely unlike weasel, mink, otter or wolverine.
