For years, the upper Forney Ridge tread was rough, with loose gravel, rocks and runoff. A multi-year project begun in 2008 rebuilt sections with flat stones, locust and native-rock stairs, drainage structures, and raised boardwalks. Those improvements make the walk more manageable than it used to be, but the stair-heavy approach is still work on the way back. The forest’s Fraser firs have also been hit hard by the introduced balsam woolly adelgid; more than 90% of park Fraser firs are reported killed.
