DOUGLAS COUNTY, Colo. (KDVR) — The Rocky Mountain Area Coordination Center (RMACC) deployed ground and air crews to extinguish a wildfire seven miles west of Larkspur on Thursday.

The fire has been named the East Plum Fire. About one acre has burned.

The fire appears to be in a wooded area without any buildings nearby. Larkspur is about 45 minutes from Denver, south of Castle Rock.

Crews were forced to temporarily stop air operations because a drone was spotted in the area.

As of about 6:45 p.m., all crews had left the area except for six firefighters on the ground.
