The Twitchell Canyon fire was active on multiple fronts again yesterday. Active fire was backing down the mountain slope about five miles east of Sulphurdale, toward Interstate 15. A large smoke column was visible from many points in the area, as concentrated fuels burned. The fire continues to accomplish management objectives that include cleaning up brush, deadfall and litter on the forest floor. As it burns in a mosaic pattern throughout the fire area, overgrown vegetation is consumed allowing areas for new grass, browse and aspen regeneration. This will all lead to improved wildlife habitat and will help prevent catastrophic wildfire in the near future.
Beginning today, firefighters will use aerial and ground ignition to burn out vegetation from established indirect control lines back to the fire front in order to speed up the containment process in the northwest corner to keep the fire from crossing Interstate 15 and Interstate 70. Most of the resources are on the northwest flank of the fire to support operations. Protection of private property and infrastructure remain the focus with emphasis on firefighter and public safety.
The south flank of the fire continues to slowly back down the slope in Pole Creek. Two Hot Shot crews and two engines are in that area and are staying in a spike camp near the fire area to monitor and contain the fire. Fire managers continue to address concerns of homeowners in the North Creek area.
