Good deal. Thank you for the lead, I'll definitely be doing some scouting!
When bear sign is located, do they usually stay in the area, or do they cover a lot of territory?
When I find an abundance of bear sign in the form of scat and fresh tracks, I figure they are still around. Last year, we started to see a bunch of concentrated bear sign in two different areas. In the morning, I saw some very large tracks that were not there the night before.
I hunted the ridge above those tracks and was about two miles from them when I shot a 6' -400 pounder that walked right up to me (25yd shot). I am not saying that it was the same bear, I am simply saying that the very large tracks belonged to a large bear like the one I shot.
I recently went backpacking in the Los Padres National Forest between Pyramid Lake and Piru Lake. LOTS of bear sign including some huge tracks and a lot of scat.....never saw one though. The tracks were only a few days old as there was a pretty good rain the week before.
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
