HAYDEN — A wildland fire has ignited along Routt County Road 53 south of Hayden. The road is closed between its intersections with C.R. 29 and C.R. 37, which is known as the haul road.

Firefighters battling the Murphy Fire spotted the smoke at about 3 p.m. Sunday, said Routt County Emergency Operations Director David “Mo” DeMorat. Once on scene, authorities realized the fire was growing quickly.

Two homes were placed on pre-evacuation notice in light of the fire. One home was evacuated, DeMorat said.

Air tankers arrived on the scene with a focus on protecting the home that was threatened.

“We diverted a couple engines from the Murphy Fire,” DeMorat said.

Firefighters also requested any available assets from other fire districts in Routt County. The Yampa, Oak Creek and Steamboat Springs Area Fire Protection Districts were sending any available equipment and personnel to the fire, he added.

According to scanner traffic, officials estimated the fire was at about 25 acres at 3:30 p.m. Sunday.
