| Zusammenfassung |
| The Cantabrian Mountains is a coastal range up to 2648 m altitude trending parallel to
northern Iberian Peninsula edge at a maximum distance of 100 km inland (~43oN 5oW).
Glacial sediments and landforms are generally well-preserved at altitudes higher
than 1600 m, evidencing the occurrence of former glaciations. Previous research
supports a regional glacial maximum prior to ca 38 cal ka BP and an advanced state of
deglaciation by the time of the global Last Glacial Maximum (Jiménez-Sánchez et al.,
2013).
A geomorphological database has been produced in ArcGIS (1:25,000 scale) for an area
about 800 km2 that partially covers the Redes Natural Reservation and Picos de Europa
Regional Park. A reconstruction of the ice extent and flow pattern of the former glaciers is
presented for this area, showing that an ice field was developed on the study area during
the local glacial maximum. The maximum length of the ice tongues that drained
this icefield was remarkably asymmetric between both slopes, recording 1 to 6
km-long in the northern slope and up to 19 km-long in southern one. The altitude
difference between the glacier fronts of both mountain slopes was ca 100 m. This
asymmetric character of the ice tongues is related to geologic and topo-climatic
factors.
