Cerro Guayaques is a prominent lava dome complex located on the border between Bolivia and Chile, in the remote region of the Altiplano. Standing at an elevation of approximately 5,597 meters, it belongs to the Central Volcanic Zone of the Andes and is characterized by its geological structure of dacitic and andesitic lava flows. The surrounding area is extremely arid, marked by volcanic ash fields and sparse vegetation. Historically, Guayaques was never permanently inhabited due to its inhospitality, but it serves as an important study object for geologists researching Pliocene and Pleistocene volcanic activity. The summit region has wide-open views of the surrounding salt flats and volcanoes of the Western Cordillera. Ecological conditions are defined by extreme temperature fluctuations and intense solar radiation, allowing only highly specialized life forms to survive. Scientifically, Cerro Guayaques is of interest as it provides insights into the tectonic development of the Central Andes. For mountaineers, the summit represents a technical challenge in one of the loneliest areas of South America.
