In this May 4, 2017 photo, Aaron Babcock, left, field coordinator with the Siskiyou Mountain Club, and Jason Middleton, sales manager with REI, use a cross-cut saw while clearing down trees from a trail in the Sky Lakes Wilderness area in the Rogue River-Siskiyou National Forest, about 50 miles east of Medford, Ore. Members of the Siskiyou Mountain Club are embarking on an ambitious task of reclaiming a historic 27-mile hiking loop through the Sky Lakes Wilderness Area in the southern Cascade Range of Oregon that is blocked with an estimated 15,000 blown-down trees, including thousands within 2008′s Middle Fork fire zone.
