I've been slowly trying to piece together a small pocket that has lots of bears but also lots of hikers, campers etc so they know how to play the game quite well. One dried up creek in particular sees a lot of action, always tracks or scat when I check it and I have a trail cam up that's gotten good bears moving on it at all times of day. One thing I can't figure out for the life of me is why they seem to only move one way along this creek bed. Every bear the camera has caught and every track I've ever seen there has been moving south to north. The road parallels a spur road that often sees rec users ripping up and down it (none of them really get off the road though) and the creek is only 20-30 yards through thick brush behind it. About 40 yards past the trail cam there's a beaver dam just before where the creek would meet the river, I've seen tracks hopping up onto the logs there and not too sure where they go after that. There is a campsite that seems to attract the loudest hootin & hollerin campers around right beside that beaver dam, not the most likely place for bears to hang out but I've been all over that mountain and the most concentrated sign is right there, maybe they like going there to clean up after the citiots. Curious if anybody has any insight into why they would only be moving in one direction on that creek though . There's grass on the other end that they've been hitting and I guess they take a different path to get to it, will have to try and figure that out with another camera. No the wind doesn't only come from one direction in that creek, possible they only use that travel corridor when it's a consistent north to south wind maybe? Would be nice if cameras had a wind meter. There's an elk trail that goes to the river, they go there in the fall when the salmon are running but haven't seen any sign from them there in the spring. Hopefully some bear experts out there are up for helping me play CSI or someone else has noticed the same thing and put the pieces together, otherwise I'll keep plugging away with the cams and rookie tracking skills.
