Nuevas perspectivas para la identificación y el conocimiento de la morfología glaciar de la Sierra del Teleno (León) y su transformación antrópica

Résumé

The Sierra del Teleno is a NW-SE trending mountain system located in the southern sector of the Galaico-Leoneses Mountains. It is characterized by the presence of remnants of glacial landforms, active during most of the Upper Pleistocene, and represented by several cirques and related deposits. Along the northern slope the glacial features are well developed, showing multiple cirques and moraine arcs. However, geomorphological remains are not well preserved in the southern flank where a few evidences of glacial and fluvioglacial activity, represented by remains of moraine deposits and terraces, are partially transformed. Moraines have been intensively affected by goldmining works carried out during the Roman times, comprising the presence of a complex hydraulic system with canals and water reservoirs used for the transport and storage of water needed for the roman works. Thus, hiding the effect of natural processes on the landscape and the identification and preservation of glacial landforms. We present the preliminary results of the mapping of glacial remains based on the integration of natural and human-induced transformations occurred in historical period.
