Trails 111, 113. The trail disappears about 4 miles from the Sawtooth trailhead. We picked up the trail in rockslides; we could see where folks made a nice path through the boulders but then the trail was overgrown again on the other side. We ended up bushwhacking ~3 miles through alders to get to Crag Lake. I don't recommend this trail AT ALL. If you want to see Crag lake, drop in from above.
