[4] Peña Blanca is within the following mountain ranges: Chilean Andes, Puna de Atacama.

Its slopes are within the territory of two Chilean cities: Diego de Almagro and Copiapó.

[5] Peña Blanca was first climbed by Sergio Kunsmann, Pedro Rosende and Etienne Vian (Chile) in November 21st 1967.

[6][7] American Alpine Journal 1957, page 74-91 mentions an ascent by Gajardo to Peñas Blancas (Feb 7th 1957).

But this was probably to the secondary summit as Kunsmann, Rosende and Vian did not find any evidence of such ascent.
