Packed up camp (trivial w/o a tent) and headed back to Rock Harbor. The duffel bag was a pain again, but it was only 3 mi. I talked to the rangers, and they confirmed that evidence of wolves and pups (prints mostly) had been seen near Scoville Point, so it was likely that I did hear pups Tuesday!
Isle Royale is amazing and I will be back. Next time I'll be prepared, and have at least a week to explore!
