Global Volcanism Program | Image GVP-11202
The Nevados de Payachata volcanic group, the scenic highlight of Lauca National Park, is seen here from the SW and consists of the symmetrical, 6348-m-high Parinacota volcano (right) and its older twin volcano, Pleistocene 6222-m-high Pomerape volcano (left). Collapse of Parinacota about 8000 years ago produced a 6 cu km debris avalanche that formed the hummocky terrain in the foreground, with the colorful Llareta plant at the lower right. Hummocks in this medial portion of the avalanche deposit are about 50-100 m high.
