Aguja Guillaumet - North ridge

16. Brenner-Moschioni

300m 30˚ 6b

Eduardo Brenner and Eduardo Moschioni (Argentina), 21/1/1981.

Description. A wonderful route on excellent rock, well worth repeating. The crux pitch can be climbed by any of the three cracks, the left most one being the easiest (6b). There are countless variations to this route. The most commonly climbed line accesses the crux pitch via the ridge climbing two pitches (5), then climbing the left crux crack to then head left, up a groove (5+), to a thin dihedral (5) and a steep double crack (6a+) to reach the ridge (4) and the Comesaña-Fonrouge route, along which it continues to the top (5 - 450m altogether).

History. During the first ascent they fixed the first two pitches and went on to completed the ascent with two bivies, one on the way up and one on the descent. Eduardo, a very well loved Argentine climber, one of the most gifted ones of his generation, died seven years later in an unfortunate river rafting accident in the Rio Las Vueltas, just a few kilometers from El Chalten. Solo ascents. Italian Korra Pesce did the first solo ascent in 2011. Carsten Von Birrckhahn did the second less than two months later.

Approach. Piedra Negra to Paso Guillaumet.

Descent. Either the Amy-Vidailhet or Comesaña-Fonrouge routes could be good descent alternatives. There are rap anchors along the Brenner route, but they require beefing up.

Six pitch variation with difficulties to 6c. The corner up high is 60 meters long and is stellar, offering very high quality climbing. In 1/2018 Austin Siadak and Colin Haley (US) climbed an alternate start just to the left (6b+, one short section runout).
