Update
So here are the pics I promised. I would have posted them earlier but I was working my butt off all weekend.
The first pic is the pile of Turkey feathers that I mentioned. In the daylight I could see that there was actually one big pile, and 3 smaller piles of feathers where the wolves or coyotes took the bird apart. Not surprisingly there were barely any pieces left, the biggest being a chunk of chewed up leg bone in the centre of the pic, pointed out by the arrow fletching. There isn't any doubt in my mind what happened to this turkey!
The second picture is of the only tracks I could find. These aren't really much to look at, I found them on the bank where the wolf jumped across. There's 2 paw-prints side by side. It looks like he slid a little as he was going to jump back across.
The next picture is of the spot where the wolf stopped & stared at me. I put a water-bottle down as a reference, 14 metres according to my range finder (but the "arc" says I should hold for 13!

). The spot on the bank where he jumped across & where I found the tracks is just to the left, outside of the frame.
And finally I took a picture of the stand from where the wolf was standing. It's too bad that this tree died this year, because this is the most comfortable stand I've set up yet!
Unfortunately I had to work all weekend, but hopefully I'll be out there more this week. I'll be sure to keep y'all posted.
Cheers.
