WAzufral is a stratovolcano located in the department of Nariño in southern Colombia, 12 km (7 mi) west of the town of Túquerres. It is the only volcano of the Western Ranges of the Colombian Andes. 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 4,070 metres (13,350 ft), and the north-western side of the crater contains a crescent-shaped lake named Laguna Verde at 3,970 m (13,025 ft). The lake is 1,100 m (0.68 mi) long and 600 metres (2,000 ft) wide. and its bright green color is a result of the sulfur and iron-based deposits in the crater. There are also two other much smaller lakes in the crater, Laguna Negra and Laguna Cristal.

WThe Nevado del Ruiz, also known as La Mesa de Herveo is a volcano on the border of the departments of Caldas and Tolima in Colombia, about 129 kilometers (80 mi) west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, since the Early Pleistocene or Late Pliocene, with three major eruptive periods.

WRitacuba Blanco is the highest peak of Cordillera Oriental, in the Andes Mountains of Colombia. It's also named Ritak'uwa, an ancient name from the U'wa indigenous people that live in the lowlands of the National Park Sierra Nevada del Cocuy y Güicán, where the Ritacuba Blanco is located. The summit is accessible from the west via the town of El Cocuy, the village of Güicán and the hamlet of Las Cabañas. The hike is fairly easy, but weather is not reliable, and a glacier must be crossed. Because of global warming, its glacier is melting at very high rates, backing down 25 linear mts per year; same is happening at amazing speeds to all other snow-covered tropical mountains in Colombia. In 1950, Ritacuba Blanco's glacier extended down to 4,500 metres (14,800 ft) above sea level; in January 2007 its lowest point was at 4,800 metres (15,700 ft) above sea level. If this melting rate continues, the glacier is expected to disappear before 2025.

The nearest peak that is higher is Cayambe, some 1,288 kilometres (800 mi) away. There is a permanent snowcap on this peak and on the nearby mountains. It is part of the Sierra Nevada de Santa Marta range, along with Pico Cristóbal Colón. The peak is named after Simón Bolívar.
