On a side note of Alaska, in Denali, hikers apply for permits and go cross country--there are few trails. That's some good solid bear country, but there are plenty of wolves there too. Check out the following links. TONS of warnings about bears--seriously, a lot--nothing on wolves. They just aren't considered a legitimate threat to humans. And out there, in the National Park, you don't get to carry firearms, it's prohibited! You hike with bear spray and a pocket knife and good ol' common sense about your food storage.
