Virtually unknown and, at the time, unseen by all but a handful of people, is the Chinchaga Fire of 1950, the largest fire ever recorded in North America. Igniting on the border of British Columbia and Alberta in June of that year, it burned eastward across northern Alberta for more than four months, impacting approximately 4 million acres, or 6,400 square miles, of forest (roughly, the combined area of Connecticut and Rhode Island, or three times the size of Prince Edward Island).
