This aerial view looking SSE down Ecuador's Cordillera Real mountain range shows three 5000-m-high stratovolcanoes that have undergone varying degrees of erosion. Tungurahua volcano in the foreground rises more than 3000 m above its northern base and has produced some of Ecuador's most powerful explosive eruptions during historical time. Altar (center) is an extensively eroded volcano of Pleistocene age. Symmetrical, undissected Sangay volcano in the background is Ecuador's most active and has been in continuous eruption since 1934.
