Below is the hunters description of the event. He was wolf hunting, not elk hunting...would be awesome to kill one with a bow. I do not get the slightest hint he was scared by this hunt. 
Fifteen was the most wolves I called in during a single day. I actually was surrounded by them while trying to get one with my bow. It was the largest pack I have ever seen. I actually think two packs had converged and I was caught in the middle. I howled in a group of six black Wolves. Then there were another six in a different pack below us. The lower pack started to howl and the two packs converged as I tried to cut them off. I got 30 yards to a few but could not get a shot with my bow. Later on more single wolves moved in as I barked and howled getting all the wolves to go crazy. I chased the wolves for about three hours straight howling back and forth. It was one of the coolest things I have ever experienced to be in the middle of wolves like that with a tag in my pocket and a bow in my hand. I know I will probably get the most response for this part of the post, with people saying, “Why didn’t you shoot them with a rifle?” This was actually during the wolf archery only season. If the rifle season had been open I could have taken my pick of the pack.
Always interesting to read the other side of the story.
I have a friend who went on a Moose hunt last year in Canada. He was telling me the wolves were always around them but never attacked. They would pace alongside him. His hunting guide claimed the wolves usually stay away and will move in after you abandon your kill during the pack out process. He said the Moose he shot was packed out in 1 trip by 5 guys, or there would have been nothing left when they returned. Interesting...
