This viscous andesitic aa flow was erupted from the Volcanes de Ajata cinder cones along a N-S fracture on the southern flank of Parinacota.  Helium-exposure ages of about 5985 and 6500 years ago were obtained from the lowermost and oldest of three lava flows of the Volcanes de Ajata.  Snow-capped Acotango, Sajama, and Guallatiri volcanoes form the horizon to the east. Photo by Oscar González-Ferrán (University of Chile).
