Cerro Zapaleri is a mountain standing at 5,653 meters in the Andes, possessing a unique geographical significance as the official tripoint between Bolivia, Chile, and Argentina. The mountain is situated in one of South America's most remote and inhospitable regions, the Puna de Atacama. On the Bolivian side, it is part of the Eduardo Abaroa Andean Fauna National Reserve. Geologically, Zapaleri is part of a massive ignimbrite plateau created by cataclysmic volcanic eruptions during the Tertiary period. The landscape surrounding the summit is characterized by extreme aridity, high UV radiation, and vast nearby salt flats. Historically, the mountain served as a vital landmark for travelers and was formally established as a boundary marker in border treaties during the late 19th and early 20th centuries. Despite its isolation, it is a point of great interest for geographers and high-altitude adventurers, as it serves as a common junction for three distinct national protected areas.
