(Portland, OR)  --  The U.S. Forest Service says it could be months before many popular hiking trails reopen in the Columbia River Gorge.  The Forest Service says response teams will begin hiking the trails in the coming weeks to assess the damage from the Eagle Creek Fire.  The Forest Service will then create a restoration plan based on the findings of scientists and engineers, who will be studying the ecosystem along with damage to trail infrastructure and hillsides in the area.
