| Paul Klenke, Sergio Verdina, Tod Bloxham, and I summited Argonaut via the Northeast Couloir route in 14.5 hours car to car (including a traverse of Colchuck). We found this route much more moderate than we expected. Not a lot of information was available on this route, since it is only described as a summer rock route in the brown Beckey guide.
The approach in the basin was quite a slog on some steepish snow. Once inside the couloir, the climbing was fun, but strenuous with the soft snow conditions. After that we climbed a short pitch of mid 5th class rock. There we encountered another party we had seen in the couloir from the approach. They didn't make the summit due to a notch, but were thinking about giving it another shot. After summiting, we found out they bailed again.
Tod went on ahead scouting the ridgeline, with me just behind him. He found the prominent notch descibed in some online trip reports, which required a rappel to get into. Tod and I downclimbed some steep snow to get back onto the snowfields, then alerted Sergio and Paul to the condition.
We then traversed some moderate snow on the north side, before gaining access to the ridge at a point about halfway between the central summit and main summit. We traversed the ridgeline, on 3rd class terrain before eating lunch together on the main summit.
We retraced our steps then rappeled the 5th class section with a full 50 meter rap. From here we traversed to the south into the East Gully, which we downclimbed. From here we cut accross the basin on the east side of the ridge towards Colchuck Peak. |
