Pumiri is a 4,862-metre-high (15,951 ft) volcano in the Andes that rises 1,062 metres (3,484 ft) above the surrounding terrain.[1] The volcano is located in the Oruro Department, Sabaya Province, northwest of the Salar de Coipasa.[2]

The volcano is formed from two volcanic cones. The younger of which may be of Holocene age and is constructed in the middle of a caldera marked by a semilunar shape.[3]: 141  Thanks to heavy erosion, lavas and eruption products are mostly found in peripheral parts of the edifice, while in the central area a deep-grounded crystalline core is exposed.[4]: 150  A breach 3.5 kilometres (2.2 mi) wide and 5.5 kilometres (3.4 mi) long with an azimuth of 139° lies in the volcano, whose summit has a maximum slope of 25°.[1] The volcano forms a lineament with Saxani and Isluga.[5]

The creeks named Qhamiña (Camiña) and on the western side Waywasi (Guayhuase) originate on the volcano.[6]: 101  Sulfur deposits on the volcano were exploited by indigenous people.[7]: 63
