Wildlife officials in Alaska are alarmed at the increase in grizzly bear attacks on humans, and they are advising the public to be extremely careful when hiking, fishing, hunting or camping.  They also advise people to wear small bells when they walk so they will alert grizzlies to their approach, and also to carry pepper spray in case of a close encounter.

The officials also say it would be wise to be alert for fresh signs of grizzly bear activity, such as piles of fresh bear poop.  Of course, you must be able to differentiate between brown bear and grizzly bear poop, so they offer the following:

Brown bear poop is usually small, and contains the remains of berries and sometimes squirrel fur.

Grizzly bear poop is larger, contains small bells, and smells like pepper.
