Klickitat County Fire District 3 says Thursday’s brush fire in White Salmon was contained at about seven acres.  In a Facebook post, the district indicated the majority of the fuel for the fire was uncut grass, Scotchbroom and blackberries.  One structure that had heavy fuels up against it started to burn, but that was stopped.  Fire officials note Scotchbroom is an oily organic and can be explosive in hot and windy weather.  They emphasize the need to have defensible space on properties to protect structures.  Along with Fire District 3, crews from White Salmon, Bingen, Trout Lake, Skamania County Fire Districts 1 and 3, the Columbia River Gorge National Scenic Area, and the Washington Department of Natural Resources were all involved in the firefighting effort.  The Facebook post said the cause of the fire has been determined to be human caused and the investigation is closed.
