JEFFERSON COUNTY, Colo. (KDVR) – The Oak Fire that police suspect was human-caused was 70% contained as of Tuesday evening.

There was minimal fire activity, with the fire reaching 153 acres — a 1-acre increase “due to more accurate mapping,” according to West Metro Fire Rescue. Crews were expected to continue mopping up on Wednesday.

Firefighters were working Tuesday afternoon in steep terrain to extend a fire line around the perimeter and continue to mop up, according to West Metro Fire. Part of extending the fire line includes cutting through thick oak brush on steep, rocky slopes.
