Direct Start to Super Slab is on the Lower West Face of Redgarden Wall, roughly below the summit of Vertigo tower, which in turn is below the top of Tower One. The climb ends at Grand Giraffe ledge (i.e. the top of the Lower Ramp) very near the start to Super Slab (which summits Vertigo tower).
Redgarden is complex, and the system used on this website is but one way to subdivide and organize the various facets of the formation.
Thanks Steve, that makes sense. So this picture does belong in the other section, I will put it there. Leo Paik tells me that I can't delete this picture untill I delete all of the comments for it.
