The Coal Hollow fire burned nearly 30,000 acres and left Utah County in a smokey haze as firefighters battled the blaze throughout August. Air quality became especially poor in the Spanish Fork area.
The Coal Hollow fire was started by a lightning strike on August 4. Winds and dry conditions led to 500 foot monster flames that made fighting the fire difficult. At one point, more than 300 personnel were on hand to fight the fire. The fire was downgraded to Type 3, local incident management, on August 27. Total containment is estimated for September 12.
