Ambato, Ecuador
Ambato lies in the main valley of the Central Cordillera, the highest of the Andean mountain ranges. The city itself is carved into the side of Cerro Casigana, the mountain that dominates the north end of the city. From Ambato, it is possible to see many snow-capped volcanoes including Cotopaxi, Tungurahua, Carihuairazo, and the largest mountain in Ecuador, Chimborazo. Tungurahua lies about 40 kilometers to the southeast. The threat of eruption from the volcano is constant. On May 16, 2006, Tungurahua erupted, covering the city with a thick layer of ash.
Cerro El Cóndor
Cerro El Cóndor is a remote peak in the Argentine Puna de Atacama. As such it was probably the last major 6000m+ peak in the Andes to be climbed, with the summit reaching a height of . The volcano has the form of a massif (which covers a surface of ) constructed by two separate volcanoes; the older edifice forms parts of the northern and eastern flanks which are cut by scarps interpreted as caldera remnants. The summit region is formed by the newer edifice, and features a series of craters with diameters of and a cover of pyroclastic material and scoria. Also part of the newer phase are extensive lava flows which form the western and parts of the eastern and southern slopes and reach distances of from the summit.
