Cooler, more humid weather on Thursday helped calm the Indian Creek Fire on the Mark O. Hatfield Wilderness west of Hood River.  Two “medium” helicopters and four Super Scooper airplanes made repeated water drops on the fire, concentrating on hot areas along the north and west edges.  The fire produced much less smoke than a few days ago, showing that the fire was burning with less intensity.  The fire did gain three acres and is now 327 acres in size.   Firefighters are bracing for warmer, drier weather in the coming week, so officials say they plan to continue dropping water on the fire with aerial resources, cooling as much heat as possible.  This will also raise the humidity and make fuels harder to burn.  While aerial water applications won’t put out the fire, they can help keep the fire from growing too quickly.  The goal is to keep the fire in check until the fall rains extinguish it.
