ISLE ROYALE – The Mount Franklin wildfire on Isle Royale National Park has been 100% contained, the National Park Service announced Tuesday.

The fire was first reported Aug. 13; initial estimates put the fire at 11 acres, which was revised downward to 6 acres after active mapping of the trail boundaries.

The response included NPS wildland fire personnel and park rangers and the dropping of 4,000 gallons of water on the fire by an aircraft.

A wildland fire crew of 10 from Minnesota, which arrived Aug. 14, left Sunday. An incident commander from Hiawatha National Forest, who arrived Aug. 14, continues to monitor the burn area.

All affected trails, campgrounds, and docks are open. Affected cross country camping zones remain closed.

Hazards may still exist. People hiking through the burn area are asked to stay on the trail for their safety. Rock cairns are in place on the Mount Franklin Trail to guide hikers through the burn area.

The cause of the fire is still being investigated. Investigators are seeking information about an illegal fire and associated camp on the Mount Franklin Trail the evening of August 12 and into the morning of August 13. Information can be submitted anonymously.

Anyone with information is asked to call or text the tip line at 888-653-0009, submit it online at nps.gov/SubmitATip, or email nps_isb@nps.gov.
