A brush fire on Walden Ridge just outside downtown Oliver Springs was most likely deliberately set, according to state Forestry officials. Smoke was spotted in the area shortly before 2 pm Tuesday and crews from the State Division of Forestry responded as did firefighters from Oliver Springs, Blair and Marlow fire departments. Using hand tools and leaf blowers, officials said they were able to dig fire lines and contain the blaze within an approximately 12-acre area on a steep, rocky hillside above Railroad Avenue in Oliver Springs. Officials say that the fire was likely started by someone hunting within the past couple of days in order to smoke out animals in the brush. Neighbors said that raccoon hunters are not an uncommon sight on the ridge. The fire burned only the top layer of vegetation, thanks to recent moisture and cooler temperatures. No injuries were reported and no structures were threatened by the fire.
