El Tronador and Catedral Group, New Routes above Bariloche. During January a climbing instruction and certification course was carried out on the Argentine-Chilean frontier. The course, organized by the Argentine Federatión de Ski y Andinismo, was directed by me, who am a Spanish high-mountain guide. Thirteen of the best Argentine climbers took part. The skill of the group, the good weather and a camp on the glaciers of the Cerro Tronador facilitated a number of new routes, four on el Tronador and six in the Catedral group. We did the following on el Tronador: northeast ridge of the Argentine summit, mixed climbing, by Paul Cottescu, Daniel Horecky, Jerónimo López; variant of normal route via southeast face of International summit, ice, by Alejandro Randis, Alberto Tarditti; another variant of the same, ice, by Antonio Arko, Ariel Murtagh, all three on January 5; northwest face of Chilean summit, ice, by Jorge Arias, López, Randis, on January 6. The following were done on rock in the Catedral group: west face of the Torre Principal, by Pedro Friedrich, Randis; northwest face of the Torre Principal, by Lopez, Tarditti, both on January 11; east face of Punta Philip Heron, by Randis, Tarditti; west face of Aguja Frey, by Arias, Cottescu, southeast spur of el Abuelo, by Friedrich, Horecky, Jorge Jasson, all three on January 13; wall below the Astilla, by Horecky, Randis on January 14. Before the course we did another new route in the Catedral group: the north spur of el Abuelo, by Alicia Barba, Jasson, Lopez. Nearly all climbs are rated very difficult.
