Global Volcanism Program | Image GVP-11245
The snow-speckled volcanic complex near the center of this NASA International Space Station image (with north to the lower right) is the Patilla Pata complex. The age of this volcano is uncertain, and Holocene activity has not been confirmed. This extensively eroded andesitic and basaltic volcano lies along a graben extending NE from glacier-covered Pomerape volcano at the upper right, which is part of the Nevados de Payachata complex that includes Parinacota volcano.
