I've got a drainage I've elk hunted up in the NE Bighorns and for the last few years we've been calling it "Wolf Alley". Used to be a great place to bugle. Now the elk are stone quiet and if you bugle, wolves will answer from both ends of the canyon. I've got fleeting glimpses a couple times, a buddy got one shot off there.
A couple years earlier I was hunting the west side of the Bighorns, up near Cloud Peak. Drove up in the early evening, set up to sleep in the back of the pickup. Coyotes serenading all around for an hour or so once it got dark. Then there was one long wolf howl. Not a peep out of the coyotes the rest of the night. Another buddy saw a big black wolf the next day. Again, no shot.
I've been seeing and hearing wolves in the Bighorns since around 2011. I got off one shot about 4 years ago. All I can confirm about that is that not all wolves are 150# monsters. I thought it was huge and 300 yards, More likely close to 70-80# and only 150 yards. I shot over it. Like coyotes, they don't stick around for a second chance.
