The Crosho Fire in South Routt County was 24% contained at 2,072 acres Thursday morning, according to a news release from the U.S. Forest Service.

No structures have been damaged or destroyed by the fire as of Thursday morning, although 67 structures remained threatened.

Over 340 firefighting personnel were working on the scene, along with 10 engines, four water tenders, one aircraft and two dozers.

Infared flights continued to detect isolated and scattered heat pockets across the fire’s perimeter and concentrated areas located within the interior along the North Hunt Creek Drainage, according to the release. Crews will continue to reinforce lines and work toward containment.

“Aerial resources are slinging gear to crews working on remote sections of the fire’s perimeter,” the news release states. “Multiple engines are patrolling the fire perimeter during the night shift.”

“There are several active wildfires in the surrounding area that are contributing to overall smoke in the Yampa River Valley,” continues the release. “Later this week, another weather disturbance will move over the region.”

Zones 2, 3, 4, 5, 7, 8 and 9 remained under “Set” pre-evacuation orders as of Wednesday morning.
