Ambrona and Torralba archaeological and palaeontological sites, Soria Province

The Torralba and Ambrona sites (Santonja et al., in: Santonja and Pérez-González, 2005 (eds.): 18-39) are 150 kilometres north east of Madrid on the watershed between the Ebro, Duero and Tagus Rivers, in the southern part of Soria Province. This is a strategic transit zone between the highlands of the Iberian Meseta (plateau) and the Jalón River Valley. An oblique perspective generated by a digital terrain model shows the two sites between reliefs drained by tributaries of the Atlantic slope Duero and Tajo Rivers. To the east, the clear outline of the Jalón River canyon, which flows into the Ebro and eventually into the Mediterranean (Fig. 1).
