Containment of the Top of the World Fire west of the Catherine Creek recreation area between Bingen and Lyle was increased on Thursday to 70 percent.  According to a Columbia River Gorge National Scenic Area spokesperson, firefighters continued suppression efforts and are working to mop-up the 171 acre fire.  People are asked to avoid the area surrounding the Catherine Creek trail system as the trailhead is serving as the command post for the fire and firefighters are actively working in the area.  Smoke will remain visible from Washington State Route 14 and Interstate 84.  The NSA says a formal review of the circumstances that led a prescribed burn on Monday to escape and ignite this wildfire will begin in the coming weeks.  All declared escaped prescribed fires undergo a formal review.  Strong, gusty, and erratic winds on Monday afternoon led to increased fire activity resulting in numerous spot fires outside the burn unit.
