Climbs the arête immediately left of the normal start to Lyons Corner House. From the obvious spike bridge up to a stiff rockover which gains the base of the niche. Layback the right side of the niche and continue up the arête to gain the traverse of Lyons Corner House. Finish up this or Erb. The grade assumes a side runner to protect the start. Probably best considered as an independent start to Erb which then provides a very continuous E3.
