Quebrada Quepiaco is an intermittent stream located in the San Pedro de Atacama area of El Loa Province, within the Antofagasta Region of Chile. Situated in one of the world's most arid landscapes — the Atacama Desert — this quebrada (dry ravine or gully) flows only periodically, typically in response to seasonal rainfall or snowmelt from the surrounding Andean highlands. As an intermittent watercourse in this extreme high-desert environment, its character is shaped by the harsh, hyper-arid conditions of the region, with flow patterns tied closely to precipitation events rather than consistent year-round water movement.
