The Indian Creek Fire in the Mark O. Hatfield Wilderness has grown by 21 acres since Monday to 356 acres.  The growth has occurred on the southwest edge of the fire.  On Tuesday smoke from other fires in the region made visibility too poor for Super Scoopers to fly and drop water on the Indian Creek Fire.   Helicopters were able to work on the fire part of the day.  The smoky conditions also kept the fire quiet, with little acreage gain.  Two firefighters hiked fourteen miles of the Eagle Creek Trail from the Indian Springs Campground down to the trailhead near Interstate 84.  They took photos for documentation, checked fire activity on the parts of Indian Creek Fire visible from the trail, and watched for spot fires on the eastern side of Eagle Creek.  With the smoke limiting visibility and fire activity, the fire was not showing many signs of heat.
