Last week's snowfall helped firefighters, but was not enough to extinguish several blazes burning in northwestern Minnesota. The largest is a fire near Red Lake that has burned more than 38 square miles and is about 30 percent contained.

A grass fire burned more than a thousand acres near Cleveland, Minnesota. Seven departments battled the blaze, which spread through the dry grass so fast one firefighter said it "was like burning gasoline." The DNR warns that the lack of snow cover, low humidity, and high winds make the fire danger high in southern and central counties.

The largest, near Greenbush, burned about 45 square miles since it started last week. Nearly 200 firefighters were assigned to the fires, which burned mostly brush. All three fires remain under investigation.
