Was walking in Yellowstone and someone coming the other way told us there was a grizzly on the trail but all I had to do was clap my hands and it would shoo away. I turned around and made a bee-line back to safety not wanting to test out her advice.
Montana Grizzly Bear Notice:
In light of the rising frequency of human/grizzly bear
conflicts, the Montana Department of Fish and Game
is advising hikers, hunters, and fishermen to take extra
precautions and keep alert for bears while in the field.
We advise that outdoorsmen wear noisy little bells on
their clothing so as not to startle the 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 poop. Black bear poop
is smaller and contains a lot of berry seeds and squirrel fur. Grizzly bear poop has little bells in it and smells like pepper spray.
