I have some friends who've done week-long ski tours in remote parts of Siberia and the Russian Far East. Their guides all carried serious rifles or shotguns with slugs, and made sure everyone in the party knew how to shoot.

Their closest Grizzly encounter was a bear that stumbled across them, and charged at their lead skier from ~200m out. The guide shot the bear twice, but it still managed to get within 20m of the group before it dropped.

Here in the US, I know two hikers who've been attacked by Grizzlies in the Rockies, and another guy who got jumped in Alaska. All three survived, but required medical evacuation and hospitalization... The guy in Alaska nearly bled to death from a broken rib tearing into the blood vessels feeding his kidney.

So I'm not sure what the likelihood of bear attacks would be--but it does happen, and the consequences can be quite severe.
