We explore backroads, old tracks, new trails, and new potential routes whenever we can.     On Greenstone Mountain, we have explored backroads heading toward the west side of Chuwhels Mountain and the lakes of the area.    On one of the lacks a track goes in to Chuwhels Lake.    We found an informal campsite there, rarely used.    We spotted a faint trail that went around the lake, and to our surprise, we found an old cabin there, probably used for fishing and/or hunting.    It is hidden away in a remote backcountry spot so it may stay intact for a while yet.
