Suppression efforts continued on the Top of the World Fire on Forest Service land west of the Catherine Creek recreation area in the National Scenic Area between Bingen and Lyle.  Forest Service officials say the fire’s forward progress was stopped Tuesday morning.  Firefighters worked on Wednesday to reinforce containment lines, as crews focused on extinguishing hot spots closest to the fire perimeter.  Firefighters were able to walk the perimeter of the fire and more accurately map the fire footprint at 170 acres.  The fire started Monday from a planned prescribed burn.  Following a shift in wind direction and an increase in wind gusts the fire spotted outside the burn area.  The public is asked to avoid the area surrounding the popular Coyote Wall and Catherine Creek trail systems as firefighters are actively working in the area.
