West Metro Fire Rescue announced the evacuations Monday but didn’t say how many homes or residents were affected.

The fire department said the 300-acre fire was 90 percent contained Monday night.

Officials said they didn’t expect any further evacuations, and The Denver Post reported that by 9:20 p.m. at least some evacuees had returned.

The fire was burning on 6,800-foot Green Mountain, inside a city park in suburban Lakewood. The flames were visible from downtown Denver, about 12 miles to the east and about 1,300 feet lower.

The cause wasn’t immediately known.
