More containment line completed in Dalton Highway Complex

Warmer temperatures are expected today across the Interior, with shower activity becoming more minimal. While all fires have received precipitation for several days, fire history in Alaska has shown that the duff layer creates a unique fuel where wildfire can burn deep beneath the surface and smolder for days and even weeks, reigniting fuels at the surface when weather conditions become favorable. With this knowledge, firefighters are maintaining in a state of readiness despite the reduction in fire behavior in the past several days due to the wet weather. The ongoing wet weather allowed firefighters to put containment lines around the Idaho Bar Fire (#555), and they will continue to mop up hot spots in the northeast corner. Fire crews continued work on preparatory actions on community and cultural sites in and around Rampart.The MM 125 Fire (#441) showed minimal fire behavior; crews continue work on hotspots on the southern perimeter to keep it east of Dalton Highway. The Curky Fire (#318), Prospect Fire (#494), Troublesome Fire (#359),and Huron Fire (#372) all remained inactive. With the decrease in overall fire activity on the complex, personnel are beginning the process of removing tools and equipment from the field.
