MASONVILLE, Colo. (CBS4) — A heavy air tanker dropped fire retardant on a hillside near Masonville where firefighters worked to contain a small brush fire.

The fire was approximately three to four acres in size as of late Saturday morning, according to Loveland Fire Rescue Operations Chief Greg Ward. Later in the day it was fully contained.

A brush fire burns on Milner Mountain as seen from Horsetooth Reservoir.

Thirty firefighters were trying to contain the fire on the northeast side of Milner Mountain, south of Horsetooth Reservoir.

The air tanker was focusing on the fire’s containment.

A 20-person hand crew was also en route to help current crews with mop-up.

“There’s a lot of saw work to do,” Ward said.

The fire was most likely the result of a lightning strike Friday evening — as were two other fires in the area. It probably smoldered overnight and was detected by residents shortly after 9 a.m. Saturday.
