He actually knew we were there, when I spotted him, he was 550 yards away on my range finder, and was watching us. We tried a hand squeaker and howling to get him closer, being he knew we were there, he coulda cared less about the calls. So we stayed single file walking close together (2 of us) straight towards him in plain sight. He backed off about 15-20 yards as we stalked, but allowed us to get into the 450 yard mark. Our setup took only a couple minutes, but he just sat and watched as we did set up her and the rifle and the phone skope. I tried howling at him from the 450 yard, but same thing, he just sat and watched.
He wasn’t an old wolf, I guessed him to be 80-90 lbs. I think if it were an old wolf, he wouldn’t have stuck around to long.
