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.
