Minnesota wildfires: The latest
Camp House fire:
The Camp House wildfire started around 1 p.m. on May 11 in Ault Township, about two miles northeast of Brimson, Minnesota.
Authorities say that on May 24 the fire remains about 90% contained and is just over 12,000 acres (unchanged since May 22).
Firefighters are still utilizing the "full suppression strategy" and add that containment around the fire perimeter appears strong and is "holding well."
The Eastern Area Incident Management Team (EAIMT) says this phase is essential for helping the land recover more quickly, especially in areas where bulldozers and other equipment were used to prevent fire growth.
What caused the fire:
EAIMT says the fire initially started on private land and moved into the Superior National Forest.
While the report states the cause of the fire is still under investigation, St. Louis County Sheriff Gordon Ramsay previously told FOX 9 the fire appears to have started with a camp fire that was left unattended. He added that the DNR has identified the person who started the fire.
