More than 140 buildings have been destroyed and 20,000 acres of forest burned by a trio of wildfires that continue to rage in northern Minnesota. The Brimson-area Camp House Fire, which ignited Sunday, now spans roughly 12,000 acres after spreading rapidly to the north and northeast Monday.

Wildfires have exploded in size across parts of northeastern Minnesota north of Lake Superior, destroying at least 40 homes and buildings, as unseasonably high temperatures and low humidity will continue to drive dangerous fire weather on Tuesday.
