Alfonso Benito Calvo, the scientific supervisor at the Digital Mapping and 3D Analysis Laboratory at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), has participated in a paper published in the Journal of Maps on the evolution of the landscape in the Ojo Guareña Valley. The study has furnished the first results on the evolution of the landscape and the formation of this great karstic cave complex in the north of the province of Burgos (Spain), which is one of Europe’s largest.

In the study, which consisted of a geomorphological analysis of the territory and the compilation of a detailed mapping, the landscape units, or the landforms, were recognized by aligning this with the published speleological information about the karst complex. The geomorphological mapping made it possible to distinguish no fewer than 13 phases of erosion and lowering of the relief, occurring mainly during excavation of the valleys in the Quaternary. Eight of these phases have been correlated with the formation of the cave levels in the Ojo Guareña karst complex, that took place from over 1.2 million years ago to the present day.

“As erosion of the valleys that was lowering the relief progressed, the waters from the rivers infiltrated into the limestone rocks at ever deeper levels, forming the great network of cavities at Ojo Guareña,” says Benito Calvo, who directs the Geomorphology and Formation Processes line of research at the CENIEH.
