View Comments Although small in size, the Boulder 2700 Fire burning along the southeastern rim of Flathead Lake is currently categorized as the number one priority fire burning in the Northern Rockies geographic area. Just 1,200 acres in size, the Boulder 2700 Fire has already destroyed at least two dozen structures along the eastern shore of Flathead Lake and threatens another 250 along the U.S. Highway 35 corridor. "The downdraft winds are what got them," Fire Information Officer C. T. Camel told the Lake County Leader on Sunday. "Then it started spotting downhill and across the highway." The fire is burning in steep terrain with heavy, downed fuels.
