Crews on the Whisky Creek Fire in the Mark O. Hatfield Wilderness took advantage of a break in fire activity brought on by cool, wet weather to continue work on contingency lines along the area south of the fire. Fire activity is expected to increase in the next few days as hot and dry conditions return to the area. The fire is 891 acres in size, with no containment. Central Cascades Interagency Management Team Public Information Officer Paul Brooking says with the complexity in dealing with the fire, it will take a long time to fight it. Brooking says it will probably take a season-ending event like heavy rains to fully extinguish the fire.
