scat?
You can buy dog/coyote urine spray. But for polar/brown bears this would be an attractant. Moreover, as grizzly populations explode they are increasingly interbreeding with polar bears - which corresponds to greater off-season activity by these predators.
This is a bit too far inland for polar bears typically, but not unheard of... Greater issue would be timber wolves. When I spend time out in the bush, I am honestly more concerned about running into a moose while not paying proper attention. They will charge and kill you if near a calf.
