Glaciar Norte is a glacier located on the volcanic peak of Popocatépetl in the Mexican State of Puebla.[1] In 1964, the glacier was estimated to be 600 metres (2,000 ft) long and cover .2 square kilometres (0.077 sq mi) on the north side of Popocatépetl. Glaciar Norte is connected to Glaciar del Ventorrillo, which lies to the west.[1] In a study published in 2006, all the glaciers atop Popocatépetl had essentially disappeared due to increased volcanic activity.[2] In the 1990s, the glaciers greatly decreased in size, partly due to warmer temperatures but largely due to increased volcanic activity.[3] By early 2001, Popocatepetl's glaciers had become extinct; ice remained on the volcano, but no longer displayed the characteristic features of glaciers such as crevasses.[4][5][6]
