For your information:

In light of the rising frequency of human - grizzly bear conflicts, the
Alaska Department of Fish and Game is advising hikers, hunters, and
fishermen to take extra precautions and keep alert of bears while in the
field.

We advise that outdoorsmen wear noisy little bells on their
clothing so as not to startle bears that aren't expecting them. We also
advise outdoorsmen to carry pepper spray with them in case of an
encounter with a bear.

It is also a good idea to watch out for fresh
signs of bear activity. Outdoorsmen should recognize the difference
between black bear and grizzly bear shit. Black bear shit is smaller and
contains lots of berries and squirrel fur. Grizzly bear shit has
little bells in it and smells like pepper. :-)
