Hells bells that alpine journal article is gripping reading!
to Burton83:
had an unsuccessful attempt on Rasac in 2005, guided by John Biggar. It was called off pretty early on when it was clear the glacier conditions were much worse than expected. I got the impression things are changing pretty rapidly there. And that the major peaks in the huayhuash are all serious undertakings.
We we did do Diablo mudo; it’s a stunning viewpoint (photos in my gallery) but probably too easy for what you’re looking for.
