2wd higher clearance capable to current road's end at the top of the ridge directly east of Bush River (approx 6km). Definitely evidence of recent backhoe tracks so Pacific Woodtech is maintaining this ROW (which by extension means there will likely be future extraction up there).
Rocky along the canyon section (km 4-6) requiring some clearance and moving rocks. This section of the road will fall into the canyon below one of these springs.
