Temporary Flight Restrictions are in place over certain portions of the fire area. Visit the Federal Aviation Administration (FAA) website for more information.
Fire Restrictions
Superior National Forest Forest-wide Fire Restrictions are also in effect.
Weather and Fire Behavior
Temperatures will remain warm today with highs in the 80s. Relative humidity will still fall into the 40s as a result. Winds out of the west/southwest will increase in strength and slowly turn from the west/northwest as a cold frontal passage occurs. Gusts of 28-34 miles per hour are expected for the afternoon and evening. There is a 60% chance of showers and thunderstorms this afternoon as the front passes. One or two storms may be severe with large hail and damaging wind gusts. Frequent lightning and brief downpours can also be expected with these storms. Cooler air arrives this evening.
Expect increasing fire behavior today in areas that did not receive precipitation. Warm temperatures and strong winds will support active surface fire, with potential for isolated torching in pine and mixed wood fuels. Anticipate afternoon smoke clearing and the warmest temperatures to provide the most fire activity, just ahead of thunderstorms. Any new fires will exhibit increased resistance to control.
Operations
Non-Boundary Waters Canoe Area Wilderness Wildfires
- Camp: Approximately 4,374 acres. Location–5 miles north of Winton. Yesterday, crews worked between the Camp Fire and the Bear Trap fire to improve the Echo Trail system to have an improved line on the south that connects between these fires. Four handcrews continued to build direct handline along the entire southern perimeter of the fire, connecting to Newton Lake on the east and other natural features on the west. Today, crews will continue to build and improve direct and indirect lines and structure protection will continue along Fernberg Road, identifying structures and potential for contingency lines to the south and east out to Snowbank. Fire managers are also coordinating with Minnesota Power on the power infrastructure and hydroelectric plant.
- Sioux: Approximately 12,295 acres. Location–North of the Echo Trail and east of Jeanette Campground. Portions of the fire are burning in BWCAW. Handcrews continue to work on establishing direct handline on the southern perimeter of the fire that crossed Echo Trail including handline, hoselays and a sprinkler system. This work with handcrews will continue today. Mastication work was completed around Moose Loop and crews will work in this area today to install a sprinkler system around structures in the Moose Loop area. Firefighters continue working further south from the immediate fire perimeter to develop a plan for additional indirect containment lines.
- Little Knife: Originated in Ontario and crossed into the United States. The approximate fire acreage in the Unites States has been reduced to 4,958 acres due to more accurate mapping in the United States. Fire managers are developing a strategy to address critical values at risk while providing for firefighter and public safety. Managed by the National Incident Management Organization (NIMO).
- Bear Trap (Bear Trap and Dark Fires combined): Approximately 37,623 total acres (29,556 acres in the United States). Location–South of Lac La Croix, 20 miles N of Ely. Structure protection with hose lays and sprinklers continued around the northern edge of Big Lake in Whispering Pines and Big Lake Lodge as well as private properties on the south side of the lake. Aircraft was used on the fire yesterday, using water to keep the southern portion of the fire within the existing fire perimeter. Today, structure protection will continue around Big Lake as well as crews and equipment will begin clearing and widening the Echo Trail to the east to connect the Echo Trail to the Camp Fire and to the west towards the Sioux Fire. Additionally, structure protection will begin on structures along the Echo Trail between the Bear Trap and Camp Fire.
- Thumb: 16,812 total acres (16,478 acres in the Unites States). Remote & located 6 miles South of Gakijiwanong Anishnaabe Nation Canada. Cause: Fire managers flew this fire yesterday and observed very minimal smoke along the northern perimeter where the fire has burned to natural barriers to the north. The majority of fire activity was along the southwestern perimeter of the fire area, where the fire is backing down into natural barriers, close to the northern perimeter of the Sioux Fire.

History
On the evening of July 6, a dry thunderstorm moved across northeastern Minnesota and southern Canada resulting in more than 1,000 lightning strikes, causing dozens of fire starts. As unprecedented dry and warm conditions followed in the days after, fires were detected across Cook, Lake and St. Louis counties. Where fires were accessible by ground, firefighters were able to work to keep some of the fire perimeters small in size, however due to the number of fires, locations and number of firefighters and equipment, some of the fires continued to smolder and grow in the following days. Local fire managers ordered many additional resources including engines, hand crews, aviation resources and two incident management teams to support the firefighting efforts. While some of the fires were contained, several have continued to grow due to record breaking high temperatures and low humidity. Additional firefighters, equipment and support staff continue to be ordered including a Complex Incident Management Team.
