The Bull Complex Fire on the Mount Hood National Forest twelve miles northeast of Detroit grew just under 1,000 acres on Sunday as temperatures reached into the mid-80s and relative humidity dropped to the high teens.  The 10,370 acre fire was mainly active to the west and south, burning uphill in the Elk Lake Creek and Mother Lode Creek drainages.  It is burning rapidly through the 2011 Mother Lode Fire area, consuming the large dead and down material which is much drier than the live timber stands.  The fire is nearing the border of the Willamette National Forest.  There are no evacuation warnings or orders at this time.  On the eastern side of the fire, firefighters continue to improve their pre-identified containment lines and successfully prevent additional spread to the east and north.  Winds shifted to the west overnight, dropping temperatures and raising humidity, and the fire should be less active today under those conditions.
