Geomorphological and geochronological studies carried out in the different mountain ranges of southwestern Europe and the Mediterranean Region show two scenarios of glacial evolution: (i) local glacial maximum (GM) prior the global Last Glacial Maximum (LGM, 18-21 ka); and (ii) local GM coeval with the global LGM.

The goal of this project is to reconstruct in detail the evolution of the glacial fronts during and after the local GM in the central Cantabrian Mountains. The study area includes a 20 km long portion of the Cantabrian divide covering a total surface of 220 km2, which includes part of 2 natural reserves: the Redes Natural Park (Biosphere Reserve) and the Picos de Europa Regional Park. Previous radiocarbon studies carried out by this research group in the Redes Natural Park area suggested that local GM conditions took place prior to 33 cal ka BP, before the global LGM.

The aims of this project are: 1) to reconstruct the spatial distribution of past glaciers; 2) to investigate the temporal evolution of past glacial fluctuations applying both terrestrial cosmogenic nuclide (TCN) exposure dating (10Be) and radiocarbon analysis (14C AMS); 3) to establish comparisons between the glacial evolution of the Cantabrian Mountains and other European mountain records and global climate proxies; and 4) to test possible biases related to the application of the different dating techniques in the same glacial record.


The results of this project will provide us solid arguments to understand better the role of local topo-climate factors in the evolution of mountain glacial fronts from North Iberian Peninsula and Southwest Europe.
