Fire officials say the Bull Complex on the Mount Hood National Forest 12 miles northeast of Detroit grew approximately 774 acres on Thursday, putting the size at 8,548 acres.  It’s burning closer to constructed containment lines on the south end of the fire, where firefighters have been creating multiple strategic locations to intercept the main fire when it reaches them.  Fire officials say experienced fire crews, unmanned aircraft and helicopters have strategically burned small areas between the main fire and containment lines over past few days to remove fuel ahead of the main fire.  The south end of the fire is where firefighters are focused most to establish access into the fire’s edge.  Within the 43 total miles of fire perimeter, significant portions of the fire’s perimeter are currently difficult to access and present multiple safety hazards for ground forces.  On the north, east, and west sides of the fire, the fire is burning slow and steady while it moves closer to the 2020 Beachie Creek and Lionshead Fire burn areas that lack available fuels,
