25-03-03 - 25-03-06 / 3,5 days / Upper valley of Rio Tranquilo/ Thijmen and Volker
We started at Cochrane at 2 p.m. with a driver, who brought us on Ruta X 901, then X903 to the house of the Soto family (Fundo San Lorenzo). It‘s around 2,5 hours to go in a quite remote area. The Sotos are the owners of Refugio Röhrer (Campo de Agostini) in the upper valley of Rio Tranquilo (7k per person). It‘s 2 hours of walk to this great cabin (oven, saw and axe, pans, space for 10, very cosy) and with bresthtaking views on the Cerro San Lorenzo, its glaciar and the Torre Grande.
The next day we went to Paso del Comedor. The pass is on the western side of the valley, south to Torre Grande, which dominates this side. The refugio is at 1020m, the pass at 2000m. First you follow a trail in the forest, then it‘s CC but marked with cairns steep upwards along a creek, later without cairns to a laguna. We surrounded the laguna on its northern end, then walked on a snow-covered glaciar along the western side of the laguna,. Finally we turned right, went up a steep snowfield to reach the pass after another 20 minutes in less steep, rocky terrain. The conditions were quite difficult, snow, that had fallen the days before, started at around 1500m. We scrambled over snow-covered rocks and stones and sunk into the snow up to our knees or even thighs. Navigation was not easy, too. So It took us 5,5 hours with light backpacks to get to the pass. We couldn’t even think about connecting this route to gpt36 OH22b on Laguna Caluqueo. From the pass it’s a long way down on a glaciar. The first part seemed doable, but you definitively need all equipment for a glaciiar. It should be explored going upwards from the laguna in order to have the possibility to return, if it turns out to be too difficult or if the weather isn’t stable. Anyway with backpacks it would be very difficult to do in one day and a camp in high-mountain terrain, possibly on a glaciar, might be necessary. For us it was 3 hours back to Refugio Röhrer on approx. the same way we came.
The next day was rainy in the morning, so we started late for exploration to the glaciar at the end of the valley. The way to the first Laguna is marked with cairns, afterwards we went CC scrambling to the southern end of the second laguna and the waterfall on the left side. We still walked up in very steep terrain in direction of the glaciar, but due to the westher didn‘t try to reach the first seracs, which would have taken another hour, if possible at all. So it was a short day in this stunning upper valley, that makes you feel, that Antarctica is not too far away. The next day we walked down and spent some nice time at the Fundo Agostini of the Soto family, before we walked to ruta X903, There we met a driver from Cochrane, we called from the Fundo (they have starlink).
