The Camp House Fire has destroyed 144 structures, according to an update around 11 p.m. from St. Louis County Sheriff Gordon Ramsay. The Jenkins Creek Fire had left a "couple structures destroyed and damaged," per Ramsay, though "the fire is too active in the area to check and get more details on those buildings that were lost."

Fire crews are contending with another day of volatile fire conditions in northeast Minnesota on Tuesday, as they continue to battle large wildfires that have burned more than 20,000 acres and dozens of structures.

The wildfires burning across far northern Minnesota have nearly doubled in size from Tuesday, with 40,000 acres having been burned as of early Wednesday morning.
