La Viña rock shelter (La Manzaneda, Oviedo, Asturias): Relation between stratigraphy and parietal engravings

La Viña rock shelter (La Manzaneda, Oviedo, Asturias) is the easternmost of the thirteen open sites with rock engravings spread along the Nalón river basin. La Viña is the largest settlement in that valley and contains the most extensive archaeological sequence, from the Middle Palaeolithic to the Holocene, as well as an important set of engravings, clustered along the rock face with diverse level of preservation. Fortea organized those carvings into two successive graphical horizons, Aurignacian and Gravettian-Solutrean. Recent topographical surveys (coordinates in the ETRS89) in the site have specified those proposals and have released new data about the spatial and chronological organization of the engravings.
