Skies over much of Minnesota looked clearer and smelled cleaner Sunday as the most troublesome air from Canadian wildfires moved east into Wisconsin. On Sunday evening, state officials canceled what had been a record-long six-day air quality alert.

Canada is battling more than 700 active wildfires across the country, roughly two-thirds of which are burning out of control, according to the Canadian Interagency Forest Fire Center (CIFFC). Smoke billowing from the blazes has blanketed central Canada and the northern U.S., prompting widespread air quality alerts.
