Original Wolves [species in Idaho before reintroduction].

I've been doing a lot of research, but can't seem to find the subspecies of wolf that resided in Idaho before the Canadian wolves were introduced. It seems like it could either be the Labrador, or the Northern Rocky Mountain, but its not really clear to me
Answer: 
According to the U.S. Fish and Wildlife Service, historical evidence documents the presence of gray wolves throughout the Northern Rocky Mountains of the contiguous United States.
