Part of the confusion around finding the starts of the climbs related to some out of date info. In our source (which is some notes from I think JRC) there was a bolt with a washer at the start of Ginsberg (as in the base of the climb). It also noted Brydens boots being there, but I think they are long gone along with the bolt and washer.
There is also a bolt with some tat at the 'slab start' for Elijah which is actually there but only obliquely referenced.
As for the routes, all I can say is that the first ascentionists really had some balls back then.....
