The Lone Rock Fire southeast of Condon remains at 40% containment, with the size edging up to 134,752 acres.  Firefighters on Tuesday worked on the eastern side of the fire perimeter to build control lines from Burton Hill to the south, with steep terrain continuing to pose challenges for control.  Crews also carried out firing operations and structural protection on the southern portion of the fire.  On the northern portion of the fire, crews continued to patrol the fireline with no change in fire activity in that area.  A Red Flag Warning is in effect today for the fire area, with the chance of lightning and thunderstorms particularly to the southeast of the fire perimeter.
