SALT LAKE CITY — Some of recent Utah wildfire victims, trying to understand why so much of Utah has burned this year, blame U.S. Forest Service officials for what they call a lack of forest management. But those officials dispute the claims, saying the state’s drought and fire conditions are so bad that no amount of wildfire mitigation would have prevented the devastation. Andy Anderson, whose family ranch was destroyed in the Cottonwood Fire, accused the U.S. Forest Service of inaction.
