The Northern Rocky Mountain Wolf
Its original habitat extended from the Northern Rocky Mountains to Southern Alberta in Canada.
The Northern Rocky Mountain wolf is a light colored wolf of medium to large size, averaging from 85 to 115 pounds. The largest found on record was 145 pounds.
Bison made up a large portion of its diet until the herds of bison were wiped out. So, when the wolves were forced to switch over to feed on cattle, they were intentionally driven to extinction.
It was removed from the federal list of endangered species in 2008
