Nevado de Atoroma, Jachacunocollo or Jacha Collo, Gigante Chico, Cordillera Quimsa Cruz, and Other Peaks. Our expedition was made up of Heiko Metz, the Bolivian Jorge Morato, my wife Ria and me. We drove from La Paz via Patacamayo, Panduro and Caxata to the Atoroma Mine at 15,750 feet. From there we made the following ascents: Nevado de Atoroma (5600 meters, 18,373 feet) north of the mine via the southwest snow ridge on August 5; P 5600 (18,373 feet) via the northwest snow ridge on August 6 and “Pirámide de Atoroma” (5650 meters, 18,537 feet) via the western snow slope on August 8 (These two peaks are the second and third peaks on the ridge that runs southeast from Nevado de Atoroma to Gigante Grande. There was another summit between Pirámide de Atoroma and Gigante Grande, which we did not climb.); and Apacheta (5250 meters, 17,225 feet) south of the mine via the north rock ridge on August 7. From the Chojñacota Mine we climbed Jacha Collo as the locals call it or Jachacunocollo (5800 meters, 19,029 feet) via the west snow ridge and then traversed to the south over the neighboring P 5750 (18,865 feet) and P 5680 (18,635 feet) on August 9. On August 10 we climbed Gigante Grande (5750 meters, 18,865 feet) via its southwest snow ridge.
