The Sylvan Fire, which started June 20, in Eagle County has reached 19% containment and remains at 3,775 acres as of Monday morning, according to Incident Commander Dan Dallas.

“The weather this week should favor continued progress on fireline construction and preparation for future burning operations,” Dallas said in a Monday morning update. “A few new crews have arrived, and two additional hotshot crews are expected soon. This will help with completing some of the more difficult portions of the fireline.”

Crews have completed a direct fireline from Sylvan Lake westward to the powerline road. South of Sylvan Lake, firefighters are prepping the primary containment line along the moist, grassy stream bottom parallel to the Eagle-Thomasville Road.

Crews are also working to contain the portion of the fire that moved south of the Mount Thomas Trail and ridgeline. Once they have completed this section, they will then clear an indirect fireline extending westward along Mount Thomas Trail as a contingency against southward spread of the fire in the steep, inaccessible portions that are unsafe for crews to work in.

Dallas said the favorable weather over the weekend and more moisture on the way is helping moderate the situation.

“Rain received in recent days will continue to keep fuels moist while moderating fire behavior. Fire spread will be limited and consisting mostly of smoldering and creeping,” Dallas said.

Though lightning is suspected as cause of the fire, the incident is still under investigation.
