In reply to sutty:
I think Proctor and Burke's effort is one of the finest ever in patagonia, even if it was an "attempt". the dihedral look horrendous. hard pitch after hard pitch, all of the committing because of the wide nature of the climbing. amazing what these guys could climb back then. hats off.
The upper portion is equally impressive. a three pitch horizontal traverse above the dihedral, then a wild groove with very hard mixed climbing. Burke described some of that climbing as his hardest ever. Their high point is 40 meters left of El Arca line, just 30 meters below the west ridge where they would have joined the 1974 route.
when you consider an effort like this you realized that in the 27 years that have passed we havent improved very much, in fact I think we have regressed. I have climbed below their dihedral 3 times now, and every time I want to reach over for a dipper. May be we should learn something from the commitment these guys had.
