South America, Bolivia, Cordilleras Real, Quimza Cruz, and Calzada

Cordilleras Real, Quimsa Cruz, and Calzada. Invited by the Bolivian president, then Dr. Víctor Paz Estenssoro, the Asociación Poblano de Excursionismo (Puebla Touring Association), supported by the Federatión Mexicano de Excursionismo, began its preparations. The following members were chosen: Adrian Aponte Barrera, leader; Raúl Sánchez López, Jesús Corona del Rosal, José Luis Moreno Colunga, César Macip Cruz, Daniel Linares Mora, Antonio Hernández Moreno, Juan Manuel Avila Pacheco, and Benjamin Acosta Flores. Communications were made with the Federación Boliviano de Ski y Andinismo, the Club Andino Boliviano and the Club Alpino La Paz. The group arrived on June 2 in La Paz. We approached very close to Huayna Potosí in the Cordillera Real by mining road and climbed the normal route on this peak, the south face. On July 12 the north summit (Cacca Aca, 19,996 feet) was climbed by the Reverend Jorge Urioste, Bolivian, and the Reverend Luis Palomera, Spanish, who joined our group, with Linares, while the south summit (Milluni) was climbed by the Bolivians Alfredo Martínez, Dionicio Fernández, Ricardo Iraola and Rodolfo Aguirre with me. Ours was the first "official” reconnaissance of the Quimsa Cruz (or Three Crosses) on record with the Federación. We reached the mining settlement of Laran- cota and from there ascended the Larancota and Pacuni glaciers, which form great cirques with an infinite number of nameless peaks of incomparable beauty. We made three first ascents: Puebla (c. 5850 meters or 19,193 feet) on July 19 by Macip, Moreno, and me with the Bolivians Demetrio Rocha and Rodolfo Aguirre; Aguila (c. 5900 meters or 19,357 feet) on July 20 by Corona, Avila, Moreno, Acosta and me; and Victoria (c. 6000 meters or 19,685 feet) on July 20 by the Bolivian Carlos Castillo with Linares and Hernandez. The Calzada group had been visited various times by local and foreign climbers. We made five first ascents: Universidad Mayor San Andrés and Universidad Autónoma de Puebla (both c. 5600 meters or 18,373 feet) on August 1 by the Bolivian Aguirre with Linares, Macip and Hernández; Enrique Izquierdo (c. 5900 meters or 19,357 feet) on August 1 by Sánchez, Moreno and me with the Bolivian Rocha; Reforma Agraria and Confraternidad (both c. 6200 meter or 20,342 feet) on August 2 by Sánchez, Moreno and me with the Bolivian Aguirre. Ours was solely a mountaineering expedition and so our altitudes are only approximate. The names and provisional altitudes were registered with the Federación Boliviano de Ski y Alpinismo. (Many of these altitudes seem too high. The highest peak of the Quimsa Cruz, Jachacuno- colla, is usually given as 5950 meters and Calzada as 5872 meters — Editor.)
