An infrared flight has put the size of the Indian Creek Fire in steep and rugged terrain in the Mark O. Hatfield Wilderness on the Mt. Hood National Forest at 63 acres.  The fire that started on July 4 began spreading slowly through the understory last week, producing smoke impacting nearby communities and Interstate 84.  Type 1 Helicopter water drops are being used to cool down the fire and keep it from rapidly spreading further.  In addition, a Warm Springs Fire Module made up of 10 people will continue to observe the fire and conduct reconnaissance for areas where fireline can safely and effectively be constructed.  The cause of the fire has not been determined.  The Forest Service trail and area closure for the area surrounding the fire remains in effect, including Eagle Creek Trail #440, from the boundary with Mark O. Hatfield Wilderness (to the north) to its terminus at the junction with the Pacific Crest Trail.  This means that Punch Bowl Falls and High Bridge are still open; however, Tunnel Falls is closed.  The closure includes adjacent trails Eagle Benson #434, Indian Springs Trail #435, Eagle Tanner Trail #433 and Tanner Butte Trail, south of Tanner Butte.  Signs are posted informing visitors that these trails are closed.  The nearby Pacific Crest Trail remains open.
