The cause of a 15 acre brush fire off Bear Mountain Road in Danbury is being investigated. 

Fire Chief Geoff Herald says no firefighters were injured, but one person was transported to the hospital with non-life threatening injuries after trying to put out flames by her house.  No homes were damaged by the fire. 

Herald says there wasn't as much wind Friday as the day before, but it was swirling off Candlewood Lake.  He says it's still very dry and made the conditions right for wildfires.  There was also steep terrain getting to the flames which made extinguishing them a challenge as well.

Mutual assistance was provided by Bethel, Brookfield, New Fairfield, Sherman and elsewhere.  The state forestry division is also on the scene.
