South America, Bolivia, Cordillera Apolobamba

Cordillera Apolobamba. Solo, I did a short journey from Pelechuco into the Chaupi Orco basin, where on November 25, 1970 I climbed P 5230 (17,159 feet) from the north. This lies on the north ridge of Soral Oeste, north of P 5320 (on Melbourne’s map in A.A.J., 1960). I then walked from Pelechuco to Poto via Lago Suches and Sina Pass, climbing two mountains en route: Huanchuchiri (5400 meters or 17,717 feet according to Melbourne; this seems too high as my altimeter gave 17,325 feet) just south of Lago Suches on November 28; Huanacuni (c. 17,325 feet) on November 29. The latter is in Peru west of Palomani Cunca and just east of the Trapiche-Abra Sina road at Caserío Choñacota.
