Fire officials reported another good day on the lines of the White River Fire on Thursday.  Incident Commander Trainee Randy Johnson said they were able to have a lot of success, with crews able to get into the bottom of the White River Canyon on the southwest corner of the fire, and other areas are beginning mop-up and suppression repair.  On Friday structure protection crews will continue to mop up and patrol in the Pine Grove area, while in the southwest section of the fire, firefighters will scout for and develop containment line in steep and complex terrain near the White River.  With temperatures in the 90s and low relative humidity, unburned islands in the fire interior are very dry and can be ignited by nearby smoldering fuels or blowing embers.  Light winds will keep fire active into the early evening.  The containment level for the 17,329 acre White River Fire has been moved up slightly to 41%.
