You might have a chance in the snow, but remember to not be right on the track. Stay downwind of them, as you would tracking an elk or deer. Just close enough to still see the track or circle out 40 yards or so and back every now and then to make sure you are still parallel. Remember you are more likely to find the animal bedded away from the track, so don't stare at the track but keep eyes up and ahead (parallel and downwind) Bears will hook back around, down wind, so they can see their back trail and let their nose warn them of approaching danger. I've never tracked one, but it has been done by others. Apparently seeing the bear is a rare occasion. Getting a shot is rarer yet. Either way, you can learn a lot about an animal by tracking for several hours--shot or no shot in the end.
