Volcán Yucamane (center) lies at the south end of a group of three volcanoes between the Río Callazas (left-center) and Río de Calientes (right-center). Laguna de Vilacota (upper right) lies east of the volcano. Both Yucamane and Cerro Caliente, the edifice immediately to the north, display evidence of postglacial lava flows. The andesitic Yucamane volcano has a youthful, well-preserved summit crater, and the volcano may have had historical eruptions. NASA Landsat7 image (worldwind.arc.nasa.gov)
