According to a press release, the closures are due to wildfires in Quetico Provincial Park along the international border in Canada. The closures include Mudro entry points #22/#23 and the Iron and Crooked Lake Corridors. Anyone heading into the BWCA should be aware of very high fire dangers. Fire managers have identified two fires that have the potential to spread across the border. Officials say the closures in the BWCAW will remain in effect for at least seven days or until it is safe to open the area again.
