Nevado El Cisne
The Nevado El Cisne (English: The Snowy Swan) is a volcano in the Central Ranges of the Andes in Colombia. Its summit is at an altitude of 4,636 metres (15,210 ft).[1] The mountain is one of the five lava domes of the Nevado del Ruiz volcano complex.[2] Despite the nevado part of the name, indicating a permanently snow-capped mountain, the summit of El Cisne is now below the permanent snow line as a result of global warming, and it is no longer considered a true nevado.[3] The volcano is located over the Palestina Fault, that crosscuts the underlying El Bosque Batholith of Eocene age, dated at 49.1 ± 1.7 Ma.[4][5]
