The Indian Creek Fire in the Mark O. Hatfield Wilderness in the Mount Hood National Forest remains at 83 acres, as the fire continues to creep and smolder.  Smoke was visible Wednesday from similar locations on the west flank of the fire where smoke was observed last week.  Air drops continue to be used to be minimize fire growth in the steep terrain that makes it unsafe for crews to directly fight the fire that started over a month ago and is expected to continue until the first major rain in early fall.  Officials indicate replacement of a heavy helicopter with a Type 2 aircraft has greatly reduced the effectiveness of drops through the dense canopy, and they will evaluate the need for an additional aircraft.
