A lightning strike started the fire on Aug. 18, and smoke stretched hundreds of miles from the Canadian border to southern Wisconsin, according to both reports.
Strong 40 mph winds blew the fire to grow 16 miles east on Monday, Jean Bergerson, a spokeswoman for the Minnesota Interagency Fire Center, told the Star Tribune.
In addition to the 200 firefighters assigned to the fire, about 25 National Guard troops, four Black Hawk helicopters and Air National Guard members were called to assist them, Minnesota Gov. Mark Dayton announced.
Although people were evacuated, no injuries were reported, and no structures were destroyed, Lisa Radosevich-Craig, a spokeswoman for the fire command, told CNN.
Because of the haze that extended 500 miles from the fire, baseball's Milwaukee Brewers decided to close the retractable roof of the stadium for the night's game against the Colorado Rockies, Tyler Barnes, a spokeman for the team, told CNN.
