With the three-day holiday weekend approaching, the U.S. Forest Service, the Oregon Parks and Recreation Department and Oregon Department of Transportation are reminding hikers, bikers and visitors that some areas remain closed due to significant dangers resulting from last fall’s Eagle Creek Fire.  Six miles of the Historic Columbia River Highway remain closed, with the section of road from Bridal Veil to Ainsworth still barraged by falling rock and trees.  The Historic Highway State Trail remains closed for about five miles between John B. Yeon State Park and Cascade Locks.  Visitors must obey signs and barricades blocking entry to closed roads, trails and campgrounds.  U.S. Forest Service officers have issued about 120 citations for trespassing in closed areas.  Most National Forest System lands impacted by Eagle Creek Fire remain closed—including the area south of I-84 up to the southern boundary of the Mark O. Hatfield Wilderness, from the Mt. Defiance Trail to Alex Barr Road and Thompson Mill Road.   For information on safe recreation, go to ReadySetGorge.com.
