Northern Minnesota wildfires force evacuations and drive hazardous air quality across Upper Midwest

Wildfires that have engulfed more than 77,000 acres in northern Minnesota and across the Canadian border are burning with little containment. Nineteen fires remain active, three of them inside the Boundary Waters Canoe Area Wilderness (BWCA), and smoke has pushed fine‑particle pollution to “very unhealthy” or “hazardous” levels across Minnesota, Wisconsin, Michigan and parts of Ontario. Between 6,000 and 10,000 people have been ordered to evacuate the BWCA, and the state has extended a peacetime emergency, keeping the National Guard on standby.

Governor Tim Walz authorized disaster assistance for Lake, Crow Wing, Stevens and Grant counties, citing damage from both the wildfires and recent severe storms. Air‑quality advisories issued by the Minnesota Pollution Control Agency, the Wisconsin Department of Natural Resources, and Michigan’s EGLE warn residents—especially those with respiratory or heart conditions—to stay indoors, limit outdoor activity and use N95‑type respirators if necessary.

Local outfitters near the closed BWCA, such as Sawbill Canoe Outfitters and the Gunflint Lodge, remain open but face cancellations and are diverting visitors to alternative sites while implementing fire‑prevention measures. Smoke is expected to linger through the weekend as winds shift, with hopes of relief after the next rainstorm.
