Nevado del Ruiz is in Colombia, South America. The elevation of Nevado del Ruiz is 5,300 meters or 17,388 ft. The range of this volcano is in Cordillers Central.The summit of Nevado del Ruiz is covered by glaciers (
nevado means "snow covered" in Spanish), which formed over many thousands of years, and have generally retreated since the last glacial maximum
. From 28,000 to 21,000 years ago, glaciers occupied about 1,500 square kilometers of the Ruiz–Tolima massif. As late as 12,000 years ago, when the ice sheets from the last glacial period were retreating, they still covered 800 square kilometers. During the Little Ice Age
, which lasted from about 1600 to 1900 CE, the ice cap covered approximately 100 square kilometers.
