Jorcada, Volcanic complex in Potosí Department, Bolivia

Jorcada is a volcanic complex in the Bolivian Andes, built along four fissures between Pastos Grandes and Laguna Colorada. Several stratovolcanoes and seven lava domes lie along these fissures, with craters measuring 0.2 to 1.5 kilometres in diameter. The stratovolcanoes are andesitic-dacitic, while the domes erupted rhyolite.

The volcanic complex last erupted approximately 95,000 years ago and has remained geologically inactive since. This ancient activity shaped the summit formations that visitors see today.

Jorcada lies between Pastos Grandes and Laguna Colorada, a landscape of salt flats and a red lagoon in the Bolivian Altiplano. Its four fissures carry seven rhyolite lava domes and several andesitic-dacitic stratovolcanoes, with craters 0.2 to 1.5 km across. The name Jorcada is also written Хоркада in Russian sources.

Climbing the summit requires mountaineering experience and proper acclimatization due to the high altitude. Bring warm clothing and weather protection, as conditions are often cold and windy.

Jorcada's four fissures carry seven rhyolitic lava domes and several andesitic-dacitic stratovolcanoes, with craters 0.2 to 1.5 km across. The youngest activity built basaltic-andesitic centres on the northwestern fissure around 95,000 years ago.
