Smoke can be seen from a brush fire that flared up Saturday afternoon near Sedalia and the outlet malls in Castle Rock.

Fire crews from both South Metro and West Douglas are tackling the fire near the railroad tracks south of Highway 67 and west of Highway 85.

West Douglas Fire tells 9NEWS the fire is 18 acres in size and completely contained - although crews are on scene putting out hot spots and some power poles that caught fire.

Colorado State Patrol says all roads in the area are open.

Someone flew a drone in the area while an air attack helicopter worked to put out the blaze. Fire crews ask that drone operators remember FAA rules barring flight near a blaze.

South Metro Fire provided 9NEWS with this video of the fire:
