+1 on Jerry's comments. I did the trail BEFORE the big washout and the Elliot crossing was hairy even then.
I'd suggest you go clockwise rather than counter-clockwise. Whichever direction you go, it's an uphill climb back to Timberline Lodge, but it's much steeper going counter-clockwise.
The main reason for suggesting clockwise is the crossing of the White River Canyon. You must experience the place to believe it. The topography of the wide canyon floor changes dramatically every year, depending on the rate of run-off. Every few years, we even regularily loose the state highway where it crosses the south end of the canyon, even despite the huge culverts. No trail markers survive. There are multiple shallow streams to wade, all unbridged, draining the mountain. It's a huge field of pumice and loose rock. You cross all this at essentially 90° to the flow. It's a slow go, but definitely not dangerous.
By going clockwise, you come downhill out of the trees and there's the canyon floor - maybe 1/3 mile wide. Maybe you're lucky and someone before you has set out cairns. However, if you look across to the other side (west), you can see the trail climbing up to Timberline. Problem solved. When I got across, I looked back from whence I had come. Even though I knew where I'd started, there was no sign of the trail, just a wall of trees, and I'd need to have left a huge mass of orange flagging tape just to be able to see where the trail was at that distance.
