MARSHALL, Minn. – A slightly acrid haze that settled into southwest Minnesota ahead of the weekend was from massive wildfires 1,100 miles away in the Texas Panhandle. The Minnesota Pollution Control Agency found that smoke concentrations didn’t warrant an air quality alert. The Texas fires are the second most severe in state history. Hundreds of homes and businesses have been destroyed and one nuclear plant put on alert. Cattle have been decimated in smoke and flames. At 1,200 square miles, the destruction is larger than the state of Rhode Island.
