Thumb Pass

@ghaz: I dont recall exactly how the connection looks from the escarpment onto that knife ridge, but I do remember domsmooth, who was with on that occasion, being concerned about it too when we go there but it turned out to be fine. Somewhere there is a route.

@smurfatefrog: that aspect shows the route that I did. The gully is hidden from this angle.

Firefox isn't working for me either as far as attachments go. Chrome and IE 9 are working though. Sorry guys, bear with me, this should get fixed with the upgrade.

I dug up some old, non-digital photos of that trip. There isn't anything particularly useful, though I did notice I have a shot looking onto the Thumb and the narrow ridge taken from the escarpment from a northerly aspect, perhaps 50m beyond. This tells me that the access onto this ridge is probably there and that it angles across to the Thumb. This clue may help you in finding your way up to the escarpment.

Yes that might be it, or something similar. I can remember certain sections pretty clearly, but not that part.

These are two photos from my trip (which was actually dated May 1997) which are the most helpful. The first shows that view from the escarpment onto the ridge and The Thumb. This is probably were the connection from the escarpment lies. The second is taken on the ridge looking towards the Thumb. The route of the pass from below is roughly where the shot was taken from (or further behind) coming up from the left.
