(WHBL-Wheeler News) - Governor Scott Walker declared a state-of-emergency last night for Douglas and Bayfield counties, where an intense wildfire destroyed over nine-thousand acres. It was finally contained around nine p-m, as a line of bulldozers circled the perimeter. Authorities said it could be several days before the fire is totally out, but lighter winds and cooler temperatures are expected to help the fire-fighting efforts today. No one has been injured since the wildfire began early Tuesday afternoon southeast of Solon Springs on Germann Road. The cause remains under investigation. The Duluth News-Tribune said the blaze started at an active logging site, possibly by sparks from machinery or vehicles. The early flames were said to be fueled by 30-mile-an-hour winds across acres of sandy soil jack-pines and red-pines. At one point, the fire line moved two miles in less than an hour. Forty-seven structures have been destroyed, including 17 homes and cabins. Roads were re-opened in the area last night. D-N-R officials are urging extreme caution in all outdoor activities statewide due to the dry conditions.
