Not bad, as it turns out, not bad at all. But these lines have proved to be worthy challenges. Here are the nine routes and their status:

South Tower of Paine, Chile, south face. Not yet, but big-wall soloist Dave Turner spent months in the Paine in early 2009, hoping to attempt the face, before an injury forced him to focus on smaller objectives.

Namcha Barwa, Tibet, west face. Nope. The 7,782-meter peak has been climbed only once, in 1992, from the south. The 3,300-meter west face has never been attempted.
Janak, Nepal, southwest pillar. Climbed! Slovenians Andrej Stremfelj and Rok Zalokar pulled off a stylish alpine-style ascent in 2006.

Mt. Tyree, Antarctica, southeast face. Not yet. Antartica's biggest and steepest alpine wall remains untouched.
Latok I, Pakistan, north face. Not yet. Several teams have attempted the line but diverted to the north ridge, also unclimbed.
Torre Traverse, Patagonia. Climbed! Rolando Garibotti and Colin Haley linked Cerro Standhardt, Torre Egger,and Cerro Torre in January 2008.
So, more than half of these routes remain unclimbed. But it would be a mistake for either climbers or the media to focus attention exclusively on these lines. As the Alpinist compilation's editor, Sean Easton, wrote in his introduction, these climbs "represent only a minute sampling of what remains to be found."
Indeed, one of the great thrills of working on the American Alpine Journal is seeing photo after photo of great unclimbed walls around the world (and those other mountains, barely in view over the shoulder of that peak in the foreground...what are they?). The world still holds enough great alpine challenges for generations of ambitious climbers to come. Time for a new article?
