Nevado del Huila volcanoNevado del Huila, a massive stratovolcano, is the highest of Colombia's active volcanoes. It is built inside an older caldera and has an elongated N-S shape composed by a series of andesitic-dacitic lava domes and its summit areas are capped by ice. Until its recent awakening in early 2007, only a single 16th-century explosive eruption is recorded in historical time from this little known volcano. Two persistent steam columns rise from the central peak, and hot springs have been present.
