Two fires started on December 30th, the MIDDLE FORK FIRE which started on this day just after 1030 hours MT due to an unknown ignition source in the area of North Foothills and Middle Fork was said to have received reports of several powerlines down, transformers blowing which has caused several grass fires from the downed and sparking lines, said the BCSO PIO on the date the incident took place. They also stated a second fire was burning near the block of North Broadway.


Firefighters would quickly knock down this fire and were holding it to one acre. Crews on scene mopping up. A WIND WARNING was issued for the Boulder County area with west winds expected to reach 25 to 40 mph and with gusts to 80 mph. A damaging wind warning was given stating it will blow down trees and power lines and to use caution, especially high profile vehicles.

A second large fire named the MARSHALL FIRE was reportedly near the area of South Foot Hills and Marshall Road, which spread quickly to Superior, portions of Louisville, and areas in unincorporated Boulder County just after 1100 hours MT on December 30th. Conditions were volatile and unsafe. At that point, the fire had burned 1,600-plus acres and was still spreading rapidly on the day it ignited. They thought the cause was powerlines but after searching the ignition point, there were only communication lines in the area, which would not have started the fire.
