This story was updated at 2:38 p.m. Aug. 30 to include the latest information on the Black Mountain fire.

Fire crews are working to extinguish a wildfire that ignited Sunday afternoon, west of the East Troublesome burn scar in Grand County.

The 170-acre Black Mountain Fire is burning northeast of Kremmling mostly on national forest land, though due to the fire’s behavior, the Grand County Sheriff’s Office has issued a pre-evacuation notice for some residents, according to InciWeb, an official reporting site for fire managers.

The sheriff’s office responded shortly before 1 p.m. Sunday to a report of a large smoke plume on Black Mountain, which is off of County Road 2 near Big Horn Park. The cause is still unknown.

A large air tanker and a helicopter made drops through the afternoon, according to InciWeb. Fire managers said they expect to burn for a long time, according to the site.
