100m, 2 pitches.
Start at the toe of the curved slabby buttress, about 15m down and left of Sylph. This climb moves diagonally R wards to pick up the arête of sylph, then follows the diagonal crack running R'wards below the second pitch of Sylph.
1): 50m. Step up R and onto the rib and follow this to arrive at the arête of the 1st pitch of Sylph. Follow this to belay as for that climb.
2): 50m. Move back R to the arête and follow this for a few moves until a crack, running diagonally out R'wards, can be gained. Follow this to its logical conclusion, then head straight up a vertical crack to a recess (and good belay if required). Easy climbing remains above this to the top of the crag. A superb pitch.
