Is this route on the south face?
Hi Sebastian, yes it is, though on the right side (if you are looking at it from beneath).
You have told me you have done on this wall a route solo years ago, didn't you?
Yep, the South Face (IV+, easier than this grade VI- pitch). It was long and tiring, mainly because of the mental demands. I couldn't tolerate getting off the route so a couple of times I had to spend almost an hour making sure I went the right way. Both times were at these long leftward traverses that headed out from an ill-defined spot. Here? or Here? Shudder!
