“…To the south of El Meicín Refuge (D4), a very large block interpreted as supraglacial till displays jigsaw-puzzle cracks with its northeast and southwest ends showing a more accentuated dismembering. In Alps, Ostermann et al (2012) post-date most rock avalanches to the Last Glacial Maximum; in Ubiñas, these deposits probably correspond to the phase III, defined in the eastern part of the Cantabrian Mountains by Jiménez Sánchez (1996), when glacier fronts were stabilized at altitudes between 1500 and 1700 m. Postglacial slope evolution, which presumably began during deglaciation, starting at 21-20 ka in the Central Cantabrian Mountains (Rodríguez-Rodríguez et al, 2018), continues at present. Some areas have experienced many changes since glaciers retreat.…”

A Geomorphological Map of the Ubiñas Massif, Cantabrian Mountains, at a scale 1:22,000 and covering 94.52 km 2 , is presented. The 'Natural Park of Las Ubiñas-La Mesa', a completely deglaciated glaciokarst, containing the highest peaks in this part of the Cantabrian Mountains, has been also declared 'Biosphere Reserve' by UNESCO. A previous geomorphological map (13.17 km 2), recording glacial and periglacial, karst, slope, fluvial and anthropic features, is now enlarged to include the whole massif. An initial analysis of the present map, planned as a basic instrument to fulfil the needs of no particular end-users, provides information about rock avalanches during glaciation, preglacial deposits, and the absence of rock glaciers formed by calcareous debris, among other characteristics of the area. This cartography, considered as a fundamental base for environmental management, could be employed as a basis document to obtain other geomorphological derived maps.

“…The LME has been dated as a pre‐LGM phase in every Cantabrian Mountain area where glacial advance dating has been performed, regardless of the dating method (Rodríguez‐Rodríguez et al , , ). However, a coeval glacial maximum has not been identified, so, for the glaciers located west of the FC, the LME occurred before 43 ka in the Sil valley (Jalut et al , ); 113 ka in the Porma valley (Rodríguez‐Rodríguez et al , ), with a near‐maximum advance at 56 ka (Rodríguez‐Rodríguez et al , , ); and 45 ka in the Picos de Europa (Jiménez‐Sánchez et al , ). The LME dates for Castro Valnera, east of the FC, yielded ages between 40.4 and 78.5 cal a bp (Frochoso et al , ) in its northern watershed, and before 29 cal a bp in the south (Serrano et al , ).…”

“…A later study in the Porma valley confirmed that glaciers still flowed down to 1130 m a.s.l. at 20.2 ka (Rodríguez‐Rodríguez et al , ). An LGM readvance imprint is clear in the Central Range (Palacios et al , ; Carrasco et al , ).…”

New 10Be dates for glacial landforms in the Fuentes Carrionas area (Cantabrian Mountains, nothern Spain) are presented. Mapped and dated landforms in Fuentes Carrionas made possible a palaeoglacier reconstruction for four glacial stages. Results were compared to other nearby palaeoenvironmental proxies, so a final approximation on the mean annual temperature and annual precipitation that caused the four glacial advance stages is proposed. Glaciers reached their maximum extension at 36 ka, in a cold and dry environment. A second advance stage took place between 18.5 and 19.5 ka, during the Last Glacial Maximum (LGM), when glaciers advanced in a wet environment, with positive rainfall anomalies. A third glacial advance was dated during the Oldest Dryas, in which climate shifted to extremely cold and dry conditions. Finally, a last stage has been identified and proposed to the Younger Dryas, in which precipitation anomalies are negligible. Our results confirm some of the previously made palaeoglacial and palaeoenvironmental inferences for the Iberian Peninsula, as well as provide valuable and accurate anomalies, which are useful for climate modelling.

Evolución glaciar y morfodinámica periglaciar en la vertiente asturiana del Puerto de Ventana (Montañas Cantábricas)

A pesar del avance reciente de los estudios sobre glaciarismo y periglaciarismo en las Montañas Cantábricas, el foco de las investigaciones se ha puesto en los conjuntos de mayor altitud, mientras áreas como el sector centro-occidental de la montaña asturiana han recibido menor atención. En este ámbito, el Puerto de Ventana constituye un área paradigmática debido a sus características altimétricas y litoestratigráficas. En este estudio se han identificado y cartografiado las formas de origen glaciar y periglaciar de la vertiente asturiana de dicho puerto, volcando posteriormente la información en un SIG y procediendo a la reconstrucción paleoglaciar y al cálculo de paleoELAs. Los resultados arrojan la existencia de tres fases en la evolución glaciar del área: Fase de Máxima extensión de los Hielos (MEH), Fase Interna y Fase de Circos. A través de estas fases, la altitud de las paleoELAs va pasando en función del método de los 1.400-1.557 en la MEH a los 1.515-1.649 y 1.650-1.838 m en las siguientes. Igualmente, a partir de una superficie glaciada inicial de 491,3 ha y un volumen de hielo de 510,7 hm3, la segunda y tercera fases muestran una reducción del 90,25 % y el 96,28 % del volumen, respectivamente. El estudio de la morfodinámica periglaciar, por su parte, ha permitido identificar morfologías relictas cuya génesis se encuentra altamente condicionada por la litología existente en el área, y geoformas funcionales de dinámica atenuada y marcado carácter estacional, en comparación con otras áreas de las Montañas Cantábricas.
