Officials say efforts on the Whisky Creek Fire in the Mark O. Hatfield Wilderness southeast of Cascade Locks are going well.  The fire has burned 1,447 acres, and there is no containment figure.  Fire officials say they plan to use ignitions to strengthen the control lines on the east side of the fire, taking advantage of predicted east winds.  Firing operations will also occur on the south side of the fire to prevent spread outside of the Wilderness.  Contingency line construction is continuing from Wahtum Lake to Hood River.  Crews also plan to construct indirect line, often using existing features such as trails, roads, natural barriers, and the Eagle Creek burn area, to contain fire to the smallest footprint possible.
