Pomerape

Parinacota Volcano to the south. The name "Payachata" means "twins" and refers to their appearance.^[3] It hosts glaciers down to elevations of 5,300–5,800 metres (17,400–19,000 ft), lower on the northern slope.^[4]

lava flows which were emplaced atop of the domes.^[5] It was active about 200,000 years ago.^[6] 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.^[7] The "Chungará Andesites" and lava dome complex of Parinacota were laid down at this time.^[8] Pomerape is associated with an adventive vent that has erupted mafic magmas. The main cone was last active 106,000 +- 7,000 years ago,^[9] the adventive vent is dated to 205,000 ± 24,000 years ago.^[10]

alpine grade PD by the east ridge.^[11] Harder routes exist on the south face, sometimes on 50+ degree snow/rubble slope. For these routes a camp can be established at 5,300 metres (17,390 ft) at the saddle between Parinacota and Pomerape. Depending on the season, the main difficulty can be penitentes
