Thanks again people. The common rule of thumb on Bear hibernation is that the sows den up earlier then boars. My first boar was some 25 years ago in the last week of the season. Wildlife manager Dick Henry was surprised he had not denned up. When the food sources drop they start shutting there body down to den and do come out and in of den state. They seem to prefer sites at the 2000 Ft elevation on northern face mountaians . Finding benches, cuts and selfs about that elevation mid to late season is prime arras to look for runs scant and the common pine tree sapling scent posts these are offten chewed on. Hope this info answers some and helps . HWS.
