very few times have a left game over night in the mountains but a few years ago my buddy shot a 5x5 bull with his bow close to dark, he found a solid blood trail and he wasn't all that far from camp and temp was dropping to upper 30's that night so he left it till morn. next morn he couldn't find it, with all the blood it didn't make sense to him that it wasn't dead, he called me to bring my "antler dog" up to put his nose to work. took him no more than 5 min to find it once on the trail. it was buried with dirt and leaves and branches and drug under a thick low hanging pine tree. we seen lion and bear tracks and both are known to bury kill. there was nothing left of that thing other than the head and antlers, and strands of carcass I have those antlers in my garage, he still tagged it and gave it to me, he said it was his fault for leaving it. my guess is a bear and some cubs filled up and buried it and lion inspected it after.
