Who's in the Hole?

I took a walk out to the Mt. Umunhum view point and came across this hole. We did some research, and the the most likely occupant is a skunk. No, I wasn't wandering around drinking a bottle of wine! But most people I know are familiar with the size of a wine bottle more so than me saying this hole is about 6 inches in diameter. (Which it is, because I measured it.)
