I was North of Fort Nelson (Helmet-ish area) fighting wildifire earlier this year and our unit crew had one hell of a bear problem. We heard some rustling in the sticks and so we fired up chainsaws, made noise, you name it and the bear wouldn't go away, it just kept on circling us about 50yards or so away (just out of visual range)
After we figured the bear isn't about to leave us alone, we packed up our stuff and walked about 30-40mins to our helipad and had chainsaws running the whole time to try and scare away the bear, no luck. We got to the helipad and about 5-10mins later we hear the odd stick breaking in the bush again, and the bear grunted a few times too, not a very good feeling. To boot, this was during the same period of time the forestry/siviculture worker was attacked around Ft St John or Ft Nelson.
