100m, 2 pitches. Descent: Abseil at 270 deg from the square cut boulder. As you descend you will see a ledge out to your left beneath a square-cut corner. Avoid during the bird season.
1) 5a. Climb the square cut corner and then move right up ledges until you reach a wide, guano covered ledge. Ascend the steep crack about 4m from the left edge of the ledge. Belay on wide ledge above (low headroom)
2) 5b. Climb the steep groove above, trending leftwards at the top. Move left and climb through an overhang into a short corner(crux). Finish up easier ground.
Some good climbing, but heavily birded.

Got lost looking for Mayday... this route sounds about right. chrism225 - Lead O/S - 05/Jul/12 with Caroline
One of these days we'll find "Mayday" on the South Pillar...if it even exists! Fultonius - AltLd O/S - 21/May/09 with Neil Adams
Exciting approach - abbed in aiming for the South Pillar but missed. Spotted the ledge at the base of Undercut Wall and got swamped by a wave trying to reach it. Decided that nothing from there looked feasible (or dry) so prusikked a few metres back up to a ledge and did a new route. Neil Adams - AltLd O/S - 21/May/09 with Ally F
