Besides some ice and rain from overnight, the traverse is dry. About halfway up the white-colored rock, just before the area in pic #21 on the route description, we found a cairned slab that, although somewhat exposed, traversed to the south over the ridge. I would not want to do the slab when wet, but when dry we could walk it carefully. The terrain on the backside of the slab was all class 2/2+ and mostly unexposed. Attached is a pic of the slab, and the terrain beyond it.
