British climbers Ruth Bevan, John Crook, John McCune, Will Sim, and Paul Swall spent several weeks in the Avellano Towers, north of Lago General Carrera, in early 2018. The climbers made several first ascents, notably the east face of South Avellano Tower (about 1,000m of climbing), which Crook had tried twice before.
