First Ascent of Sincronia — West Face of Cerro Steffen

In an impressive feat of modern alpinism, Angelina di Prinzio (Argentina), Paloma Farkas (USA), and Catalina Unwin (Chile) completed a new route on the West Face of Cerro Steffen, one of the prominent peaks of the Southern Patagonian Ice Field.

The route, which they named Sincronia, spans 900 m, featuring mixed climbing up to M4, ice up to WI4, and slopes reaching 60°. This ascent represents the second recorded climb of Cerro Steffen and the first ever on its West Face.

The project was the result of a year-long planning process. With very limited photographic and historical references—aside from a first-ascent report from 1965—the team meticulously studied the peak and coordinated logistics across three countries. The approach involved crossing Lake O’Higgins and careful timing to take advantage of a suitable weather window.

The expedition was carried out self-sufficiently, with the climbers relying on traditional mountaineering techniques, technical gear, and route-finding skills in a largely unexplored terrain. Their efforts were supported by grants from Grit & Rock, the NOLS Rothberg-Birdwhistell Exploration Fund, and contributions from Argentina’s guiding community.

Sincronia is a significant addition to Patagonian climbing: it demonstrates creativity, technical skill, and perseverance in a challenging alpine environment. The ascent highlights how modern alpinists combine careful preparation, international collaboration, and bold execution to open new lines on remote peaks.
