About the location (from Wiki):
The Navarre Bardenas are a natural semi-desert of some 42,000 ha that covers southeast of Navarra (Spain). The soils are clay, chalk and sandstone and have been eroded by water and wind creating surprising ways in which they emphasize the canyons, plateaus tabular structure and lonely hills, called seamounts. Bardenas lacks urban areas, vegetation is scarce and the many streams that cross the territory have a markedly irregular flow, staying dry most of the year. They are located in the middle of the depression of the Ebro valley at the foot of the mountains of the Yugo and the Zaragoza region of Cinco Villas. It is 45 km from north to south and 24 east-west and at an altitude ranging between 280 and 659 meters. Its area is 41,845 ha. Limited to sixteen municipalities, of which thirteen are Aragon Navarre and three of the province of Zaragoza. The Navarrese are Valtierra, Arguedas, Carcastillo, Santacara, Mélida, Rada, Caparroso, Villafranca, Cadreita, Tudela, Cabanillas, Fustiñana and Buñuel, while the Zaragozan are: Taussig, Ejea de los Caballeros and Sádaba.
