BOISE, Idaho — Idaho’s two largest wildfires are burning mostly in wilderness areas.
Officials say a wildfire on Saturday has burned 17 square miles (44 square kilometers) in the Frank Church River of No Return Wilderness in central Idaho and another in the Gospel Hump Wilderness in north-central Idaho has burned 21 square miles (54 square kilometers).
Fire officials are monitoring the wildfire in the River of No Return Wilderness but say they are prepared to respond to protect life and property if needed.
A backcountry airstrip in the area is closed due to the fire activity.
Officials say the wildfire in the Gospel Hump Wilderness has spread outside wilderness boundaries, and fire lines are being built on the southern end.
Officials say the popular Salmon River remains open to camping and boating.
