JEFFERSON COUNTY, Colo - Evacuations were lifted about 8 p.m. Monday for the Glencoe Valley Fire, the Jefferson County Sheriff's Office said via Twitter.
Returned residents were asked to be aware of first responders who remain in the area monitoring the fire.
As of 7:30 p.m., the fire's size was estimated at between four and six acres.
Earlier, Sheriff's Office spokeswoman Jacki Kelley said evacuation alerts were sent to 252 phones in the Blue Mountain Estates subdivision, west of the intersection of Highways 72 and 93.
During the afternoon, AIRTRACKER7 saw smoke and flames slowly burning up one side of the canyon. Winds were calm in the area.
Kelley said 911 dispatchers began receiving phone calls around 2:20 p.m. about a loud popping sound in the 8300 block of Glencoe Valley Road, near the Swartzwalder Mine. Residents were soon reporting lots of smoke in the area.
Kelley said a concern was that there is only one road into and one road out of Blue Mountain Estates.
Five fire agencies involved and AIRTRACKER7's cameras saw a helicopter dropping water on the area.
