In the early afternoon of Saturday August 13, Isle Royale National Park staff received reports of a plume of smoke from an apparent wildfire in the campground area. of Three Mile. Isle Royale firefighters responded to the area and discovered a small fire at the junction of the Tobin Harbor Trail and the Mount Franklin Trail. Initial assessment measured the fire at approximately 5 acres. Visitors were evacuated from Three Mile Campground and Lane Cove Campground. Visitors have also been contacted and brought from the Rock Harbor, Tobin Harbor, Mt. Franklin and Greenstone Ridge trails for their safety.

Later in the day the fire spread to approximately 10 acres. To help prevent further spread until a fire crew could be brought in to work on the fire, a Minnesota single-engine air tanker dropped 5 loads of water (approximately 4,000 gallons total) on the fire in the late afternoon. Additional firefighters are expected to arrive at the park from August 14.
