Azufral is a volcano located in the department of Nariño in southern Colombia 12 km (7 mi) west of the town of Túquerres. Its name derives from the Spanish word for sulfur azufre. The volcano is considered semi-dormant but there are numerous fumaroles in the summit crater. The summit of the volcano has an altitude of 4070 metres and the north-western side of the crater contains a crescent-shaped lake named Laguna Verde (English: Green Lake) at 3970 m (13025 ft).
