Sean, for anyone with significant off-trail experience, finding the e-ledges is trivial. It is absolutely obvious, and the path could not be simpler to follow, than if it were spray painted.
The tree at the start, showed me where it was at least a half-hour before I got to it, the first time I did it.
This time of year, with the water level down, and the brush trampled down, is probably the easiest, route-wise (other than in the snow)
