Ojos del Salado Jeschke attempted to gain two world records, one for construction at altitude and the other by beating the current 6,688 m record. A refuge hut was built at 6,100 m (a record), but on December 19 it was announced the altitude record attempt had been called off at a height of 6,150 m for a combination of factors including an insurmountable rock barrier and adverse weather conditions. A further attempt may be made in early 2018. Ojos del Salado Nevado Ojos del Salado is a stratovolcano in the Andes on the Argentina–Chile border and the highest active volcano in the
Ojos del Salado of the Nazca Plate beneath the South America Plate became increasingly shallower and this caused volcanism to shift from the Maricunga Belt to the Ojos del Salado region. The Paleozoic basement crops out only northwest of Nevado Tres Cruces. Other geologic units in the region are Oligocene sedimentary units and volcanic rocks ranging from Oligocene age to less than 1.5 million years old. The area is part of a tectonic boundary between a volcanically active region north of the boundary and a less volcanically active region south of the boundary, which is also characterized by geographical differences, e.g. the presence
