U.S. Forest Service crews on June 25 responded to a wildfire in steep terrain near Arrowrock Reservoir northeast of Boise.
The Twin Fire ignited about 10 miles northeast of the intersection of Idaho 21 and National Forest System Road 268, which runs along the Middle Fork Boise River.
The fire at midday was about 65 acres and 30 percent contained. The cause is still under investigation, Boise National Forest spokesman Michael Williamson said. It was burning on steep terrain of grass and brush.
Crews aimed to contain the Twin Fire fully by late afternoon June 26, he said.
As of June 25, the fire involved about 90 firefighters, three engines, two helicopters, and fire prevention and investigative personnel. No road or area closures were in effect, but Williamson urged drivers on NFS Road 268 to use caution due to fire personnel and equipment in the area.
“It’s still early in the season, but it is a reminder we are in fire season,” he said.
