After an almost week-long battle with two wildfires at Fort Carson’s Piñon Canyon Maneuver Site, firefighters have the Bear Springs and Callie Marie fires 75 percent contained, officials said late Friday night.

As of Friday evening, the Bear Springs fire had scorched 35,000 acres and the Callie Marie fire had burned 9,000 acres.

Both wildfires were discovered Tuesday morning and are believed to have been started by lightning.
