In reply to Hugh Cottam: Thats interesting if that's the case. But its worth remembering that quite a few ascents haven't reached the summit, but its hard to know details as that top mushroom (the crux) has varied a fair bit over the last 30 years. For example Siegfrist's "first winter ascent" didn't go to the very top. Also Patrick Pessi's ascent somehow managed to circumnavigate the top mushroom and end up in the vaccinity of the Compressor route.
Personal ethics obviously vary, but in this case i think its complicated by the fact that the last pitch is the crux, and it changes,a nd a few of the ascencionists to date haven't really known where they've been on the top 100 meters.
Is your friend on this list?
1- Daniele Chiappa, Mario Conti, Casimiro Ferrari, and Pino Negri (Italy), January 1974. This was the first ascent of the mountain.
2- John Bragg, Dave Carman and Jay Wilson (USA) January 1977. Second ascent of the peak. First Alpine Style.
3- Michael Bearzi and Eric Winkelmann (USA) February 1986. First free ascent.
4- Simon Elias and Josu Merino (Spain) February 1997 via the West Face Route.
5- Ramiro Calvo, Gabriel and Luciano Fiorenza, Max Odell, Walter Rossini (Arg) and Bruno Sourzac (France) December 2005. Bruno Sourzac made the first free and leash-less ascent.
6- Kelly Cordes and Colin Haley (USA) January 2007 approaching via Los Tiempos Perdidos (south face).
7- Jorge Ackermann, Tomas Aguilo, Charly Cabezas and Matias Villavicencio (Arg), and Rolando Garibotti (no country-or 3?), and Doerte Pietron (Germany). Doerte's is the first female ascent of the route, and the 6th female ascent of the peak (after Rossana Manfrini, Inez Bozic, Cathy Cosely, Monika kambic and Tanja Gromosek), and the first female ascent without using Maestri's Compressor route bolts. December 1, 2008.
8- Ole Lied and Trym Atle Saeland (Norway) approaching via the SE ridge by traversing above the south face. A snow mushroom along the SE ridge forced them to use some of Maestri's bolts before traversing west. December 2nd, 2008. This is the much talked about "Corkscrew" link-up, originally discussed by the English and Argentine expedition in 1968 (Fonrouge, Haston, etc). A "bolt-free" ascent of the "Corkscrew" link up remains to be done.
9- Mateo Bernasconi and Fabio Salini (Italy). December 2nd, 2008.
10- Julien Dusserre, Pierre Labbre, Baptiste Rostaing Puissant and Jerome Para (France). December 9, 2008.
11- Walter Hungerbuhler. First solo ascent of the route, first solo ascent of Cerro Torre without Maestri’s bolts, 5th solo ascent of the peak. December 9, 2008.
12- Nico Benedetti, Flavio "Manzana" Renzacci, Fernando "Capi" Irrazabal and Jimmy Heredia (Arg). December 9, 2008.
13- Cullen Kirk (USA) and Bjorn-Eivind Artun (Norway). In 13 hours from Niponinos to the summit via the Standhardt col. December 9, 2008.
If it really is something he wants to keep to himself then never mind. Congrats!
