The Big Horn Fire in eastern Klickitat County is now fully contained.  The Southeast Washington Interagency Team said this morning they have transitioned oversight of the fire area back to local jurisdictions.  Crews on Tuesday completed securing and checking containment lines, and were demobilized, with some personnel going home to rest while others were reassigned to different fires.  Acreage did increase to 51,569 acres, but that was due to better mapping thanks to unmanned aircraft flights and utilization of satellite imagery in the area of Whitmore Road.  The fire perimeter remains unchanged.  All evacuation levels have been removed, and all roads in the fire area are now open.
