Step onto the corner from the block on the N side of the arete. Make of couple of moves up to a fixed pin (needs to be replaced). Move left onto face and continue up to the large horizontal break. Either move right and grab the arete, or follow the shallow crack in the face to the top.
There is a fair amount of gear, but it is mostly small gear in shallow placements. There is just enough good gear to make this pitch worth leading.
