Thanks very much fro the link, what a great trip report! Wish I'd seen it before we departed, has some great pics and trail info.
They ran the old first section up to the washout, we'd been warned so we just went in the Nokai Dome road entrance, which is now marked Hole In the Rock on the highway. When we returned we turned left at the half-track and went around to the airport via the old road. That washout in 2006 was massive, about 500 ft across and 100 ft down & still collapsing.
