On the first day of May, Pacifico Machaca (Bolivia) and I climbed a partial new route on the impressive southwest face of Huallomen (a.k.a. Wyoming, 5,463m). The previous afternoon we had hiked to Chiarkhota base camp, and because of recent snowfall we stayed in the refuge that has recently been built there by locals. We left around 3 a.m. and started our approach through about 20cm of new snow. We hiked around Laguna Huallata and reached the base of the southwest face at dawn.The southwest face of Huallomen.

In the initial section of the main gully we struggled through short sections of knee- to hip-deep snow, which slowed us considerably. Crossing the first rock band was harder than expected—we overcame this by a short, flared, slightly overhanging crack. The following two pitches were much easier: 55–60° fresh snow, where the belay anchors were deadmen backed up with a piton. We finally reached the main steep section of the gully, where the Canaleta del Angel ( see editor’s note below) slants up left and the real climbing begins.
Unfortunately, the snow from the rainy season had not transformed into solid ice and I was unable to find safe placements for ice screws. I therefore decided to continue to the right of the existing route, hoping for easier terrain. Given the wintry conditions and the bad quality schist (the strata on this face is downward sloping, making the cracks poor for nuts or pitons), I had a hard time finding good protection, and the climbing was not as easy as hoped, with cruxes of dry tooling on mostly bare rock.
After nine pitches we reached the ca 5,400m shoulder south of the summit and descended from there along the normal route on the opposite side. It was already dark and my dear partner was in a hypoglycemic state. (I felt only partially responsible for this—Pacifico had carried an entire cheese to the top, forgetting he had it.) We named our new finish Via del Querubín (“Cherub Route,” TD+), referring to the existing route Canaleta del Angel and the fact that, despite poor pro, everything went well.

Editor's note: On September 15, 1976, Alain Mesili claimed a new route on the southwest face of Huallomen. In his 1984 guidebook, La Cordillera Real de los Andes-Bolivia, Mesili describes and marks the route shown as (2) on the photo-diagram in this report; he graded it D (400m, 60° with short steeper sections). The relatively uniform snow/ice couloir that diagonals left to the summit is very visible under good snow cover, and at the time of Mesili's ascent a broad snowfield led up to the start of it. Since then, glacial recession has made the route harder, and Yossi Brain, who marks the same line in his 1999 guidebook, estimated the difficulties at ED1 UIAA V+ 85°; it is thought to have been climbed around that time. Subsequently, in his 2004 book The Andes of Bolivia: Adventures and a Climbing Guide, Mesili marks his 1976 line farther to the left, taking a much harder gully system that he calls Canalata del Angel (1). This line is known to have been attempted in recent years, and in late July or early August of 2017, Alex Albornoz, James Baragwanath, and Mati Korten (Argentina and Chile) climbed it in a 25-hour day, rating it ED1+.
