More than 8,000 acres have been scorched but no structures have been threatened yet in the Con Shea Fire, the season's largest wildfire to date, four miles north of Murphy on the south side of the Snake River. At least eight firefighting rigs worked through the night battling the blaze, which was still out of control at sunrise.
Meanwhile, the Bureau of Land Management said Wednesday that it is investigating 19 human-caused fires this season, suspecting that four were ignited by so-called "exploding targets." The targets are popular for rifle practice and scatter debris for several feet when shattered by bullets.
The exploding targets are illegal during wildfire season—May 10 to Oct. 10—on land managed by the BLM, the U.S. Forest Service and the Idaho Department of Lands.
Additionally, the BLM and USFS have deployed Idaho firefighters to battle wildfires in Nevada, Arizona, Colorado, Utah, New Mexico, Wyoming and Texas.
Idaho's wildfire season is usually worst in July, August and September.
