Fire and ice have crossed paths in northern Minnesota and Wisconsin, where wildfires destroyed several dozen homes and burned more than 32 square miles of forest and grass Tuesday and Wednesday, only two weeks after a major snowfall and amid some still-frozen lakes.

Near Solon Springs, Wis., an area south of Duluth where many Twin Cities residents own cabins, the Germann Road fire had taken out at least 17 homes, according to the Wisconsin Department of Natural Resources. The DNR reported Wednesday afternoon that the wildfire, which it said was the largest to hit northern Wisconsin in 33 years, was 95 percent contained.

Across northern Minnesota, at least 12 homes were lost in the Green Valley fire near Menahga, which had burned nearly 11 square miles, closed roads and prompted the evacuation of a nursing home. No injuries were reported.

The 6-mile-long fire was not considered contained, although it had been surrounded Wednesday by a firebreak made by bulldozers, said Carson Berglund, spokesman for the Minnesota Incident Command System. For comparison, the 2011 Pagami Creek fire in the Boundary Waters Canoe Area Wilderness burned more than 143 square miles.

Gov. Mark Dayton signed an emergency order Tuesday night activating the Minnesota National Guard, which deployed two helicopters and two large tactical trucks to help douse the Green Valley fire.

A tricky time of year

They joined aircraft, fire trucks and heavy equipment fighting nearly two dozen blazes from near Red Lake to Sandstone on Wednesday. Berglund added that with some lakes still ice-covered, some aircraft have had to fly farther than usual to scoop water.

“That’s the trickiness of spring fire season,” Berglund said. “It comes out dry right away. As soon as the snow goes, it really starts popping, and these warm and windy days really push it.”

He also noted that clusters of normally fire-resistant aspen in boggy areas around Red Lake have burned in recent days, an indication that the effects of a dry late summer and fall have lingered even through a wet late winter and early spring.

Connie Johnson, who with her husband was ordered out of their house northeast of Menahga for several hours Tuesday night, said conditions can get dry there in a hurry because the soil is so sandy.

“We can have six inches of rain one day, and two to three days later it’s dry as a bone,” she said. Three weeks ago, snow near their home was piled 6 feet high.

Rain could arrive as soon as Thursday, with the weekend also in line for precipitation.

Officials were urging people to stay out of the area Wednesday because of smoke.

Similarly, the Wisconsin DNR cautioned residents downwind of the Germann Road fire to be alert to declining air quality. The smoke was blowing away from Duluth and Superior, Wis., and mostly over rural areas.

Nearly 100 residents of a nursing home and assisted-living center in Menahga returned unharmed Wednesday morning after spending the night on Red Cross cots in a high school gym 9 miles to the south in Sebeka.

Administrator Clair Erickson noted that the precautionary evacuation came only hours after a Nursing Home week event in which the staff provided s’mores to residents as part of a “campout.”

“We told them we were celebrating Nursing Home Week with a slumber party,” he said.
