Fire officials have updated the size of the Indian Creek Fire in the Mark O. Hatfield Wilderness today to 345 acres.  Mount Hood National Forest officials say bucket drops and Super Scooper aircraft will continue to be used as needed to check fire spread, as hot and dry weather is increasing fire activity.   Fire crews continue to identify control opportunities and contingencies for future actions if fire activity increases and the fire begins to encroach on the Management Action Points.  A Type 2 Initial Attack crew will be doing some work to improve contingency lines.  The fire is burning in a steep canyon with 75% slopes along with at least eight inches of timber litter and duff on top of loose rock, making it unsafe for firefighters to take direct action.
