Cerro Capurata, also known as Elena Capurata or Quimsachatas[3] is a stratovolcano in the Andes of Bolivia and Chile.[4] To the south of Capurata lies Cerro Casparata and straight west Guallatiri.[5]
7 October 1967 by Ignacio Morlans and Pedro Rosende[2]
Geography and geomorphology
It is on the border of the Parinacota Province of Chile (Putre commune) and of the Bolivian province of Sajama (commune Turco).[1] Compared to Acotango and Humurata, Capurata's rocks are relatively well preserved. Some hydrothermal alteration, partly associated with fumarolic activity, is present however.[6] The total volume of the edifice is 19 cubic kilometres (4.6cumi)[7] and has been eroded by glaciers. The volcano is formed by lava domes, lava flows and pyroclastic flows.[8] Sulfur deposits formed by solfataras are also found on Capurata.[9] The west side of the mountain is covered with snow and ice.[10] Two crater depressions on the summit have an appearance that suggests a Holocene age.[8]
Incan Ruins and First Ascent
A 10 by 5 metres (33ft ×16ft) ruin towards the northern site of the summit. The structure was probably built by the Inkas and it was photographed by Pedro Hauck during his last ascent in 2014.[11] The first recorded climb is by Pedro Rosende and Ignacio Morlans (Chile) in 10/07/1967.[12][13]
Elevation
It has an official height of 5990 metres,[14][lower-alpha 1][lower-alpha 2] but handheld GPS devices have indicated that it is actually 6,013 metres (19,728ft)[19] or 6,014 metres (19,731ft) high.[11]
Other data from digital elevation models: SRTM yields 5,979 metres (19,616ft),[15] ASTER 5,992 metres (19,659ft),[16] SRTM filled with ASTER5,979 metres (19,616ft),[16] ALOS 5,992 metres (19,659ft),[17]TanDEM-X 6,019 metres (19,747ft).[18]
The height of the nearest key col is 5,409 metres (17,746ft),[1] leading to a topographic prominence of 602 metres (1,975ft) with a topographical dominance of 12.08%. Its parent peak is Acotango and the Topographic isolation is 3.7 kilometres (2.3mi).[1]
