The Williams Fork Fire was first reported on Aug. 14 at approximately noon and the cause is still under investigation. The origination point was 15 miles southwest of Fraser, Colo. in the Arapaho National Forest. The fire grew in size to 6,122 acres by the end of August 16th, and became a threat to the communities of Fraser and Winter Park.

The fuels consisted of heavy dead and down beetle killed lodgepole pine and during the first week low relativity humidity of around 10 to 30 percent contributed to fire growth and behavior. After the initial three-day fire growth, the peak fire spread occurred on Aug. 20 reached 1,977 acres with a total size of 9,444.

Over the next two months, the daily fire spread was limited to between 1 and 561 acres and the fire reached it’s current size of 14,833 acres on October 27th and was declared controlled after an infrared flight Nov. 30 detected no remaining heat in the fire area.
