RAMOS CATALAN (1888-1961)
El Parinacota (6,380 m (20,930 ft)
El Pomerape (6,282 m -20,610 ft)
Chile - Bolivia border
El Parinacota (6,380 m (20,930 ft) or Parina Quta or Parinaquta is a dormant stratovolcano on the border of Chile and Bolivia. Together with Pomerape it forms the Nevados de Payachata volcanic chain. Part of the Central Volcanic Zone of the Andes, its summit reaches an elevation of 6,380 metres (20,930 ft) above sea level. The symmetrical cone is capped by a summit crater with widths of 1 kilometre (0.62 mi) or 500 metres (1,600 ft). Farther down on the southern slopes lie three parasitic centres known as the Ajata cones. These cones have generated lava flows. The volcano overlies a platform formed by lava domes and andesitic lava flows.
The volcano started growing during the Pleistocene and formed a large cone. At some point between the Pleistocene and the Holocene, the western flank of the volcano collapsed, generating a giant landslide that spread west and formed a large, hummocky landslide deposit. The avalanche crossed and dammed a previously existing drainage, impounding or enlarging Lake Chungará; numerous other lakes now forming the headwaters of the Rio Lauca sprang up within the deposit. Volcanic activity rebuilt the cone after the collapse, cancelling out the collapse scar.
Parinacota had numerous effusive and explosive eruptions during the Holocene, the latest about 200 years ago. While there are no recorded eruptions, legends of the local Aymara people imply that they may have witnessed one eruption. Renewed activity at Parinacota is possible in the future, although the relatively low population density in the region would limit the amount of damage that could occur. Some towns and a regional highway between Bolivia and Chile are potentially exposed to the effects of a new eruption.
El Pomerape (6,282 m -20,610 ft) is a stratovolcano is part of the Payachata complex of volcanoes, together with Parinacota Volcano to the south. The name "Payachata" means "twins" and refers to their appearance. It hosts glaciers down to elevations of 5,300–5,800 metres (17,400–19,000 ft), lower on the northern slope.
Pomerape is a complex of lava domes, accompanied by lava flows which were emplaced atop of the domes. It was active about 200,000 years ago. The lava domes formed first and were later buried by the actual volcanic cone, which unlike the rhyolitic-dacitic domes is formed by hornblende andesite. The "Chungará Andesites" and lava dome complex of Parinacota were laid down at this time. Pomerape is associated with an adventive vent that has erupted mafic magmas. The main cone was last active 106,000 +- 7,000 years ago, the adventive vent is dated to 205,000 ± 24,000 years ago.
The painter
Benito Ramos Catalán (1888-1961) was a chilean painter who used to sign "Ramos Catalan". Known for his marines and landscapes of the Andes and Chile, and most particularly for his mountains paintings. Most of them have the same title: "Mountains of Chile" or "Mountains landscapes of Andes", making quite difficult to know which mountain was exactly depicted, in a country which has quite a lot of summits ! To add to the difficulty, he used to paint the most famous mountains of his country under very unusual angles or with proportions that do not correspond exactly to their real size... making even more difficult to recognize and identify them for experts ! That is why today, 55 years after his death, some of these mountains paintings are not clearly identified and presented, in the public sales, as 'possibly' a particular summit of Chile or Andes...
His works are in many Chilean institutions like Viña del Mar Fine Art Museum, O'Higginiano Fine Art Museum in Talca, Valparaiso Fine Art Museum, and Navy Schools in Valparaiso and Talcahuano, Ranos.
