My father (I miss him) snared wolves for bounty in northern Minnesota in the late 1950's early 1960's.
He and his snaring partner ran 7 different snare lines & were in the woods on snowshoes 7 days a week, and still only SAW 2 wolves loose & alive in his life.
There are many more wolves seen now - my sister sees multiples most weekends going to her cabin.

Size - Dad was on a Duluth TV show in the 1950's (Rocky Teller, maybe - before my time) w/ his largest pelt - it's been described to me as covering both sides of a standard door.
