“…The moraines in the Sierra de los Grajos show the occurrence of many glacial stages that should be correlated with previous researches on glacial chronology in the Cantabrian Mountains (Jalut et al 2010;Frochoso et al 2013;Jiménez-Sánchez et al 2013;Serrano et al 2013;Rodríguez-Rodríguez et al 2016;Ruiz-Fernández et al 2016), that show a local glacial maximum previous to the global Last Glacial Maximum.…”

“…The infiltration of the subglacial water into the karst network reduces overland flow, which modifies the discharges of the pro-glacial streams and the sediments they carry. Therefore, when glacier dynamics converge with a subglacial karst (Žebre & Stepišnik 2015), a type of landscape that combines the reliefs derived from both processes, named glaciokarst, is generated (Ford 1979;Smart 2004;Žebre & Stepišnik 2015).During cold stages of the Pleistocene, these dynamics has been common in the calcareous mountains at middle latitudes (Johnson & Stieglizt 1990;Bodgdan & Leszek 1999;Goldie 2006;Lepirica 2008;Hughes et al 2010;Telbisz et al 2011;Adamson et al 2014;Stepišnik 2014;Žebre & Stepišnik 2015;Žebre et al 2016), and also in limestone outcrops of the Cantabrian Mountains were the glacial processes were intense (Jalut et al 2010;Serrano et al 2012Serrano et al , 2013Frochoso et al 2013;Jiménez-Sánchez et al 2013;Santos-González et al 2013a;Gómez-Villar et al 2015;Rodríguez-Rodríguez et al 2016;Ruiz-Fernández et al 2016). However, in lower zones where this association does not occur, karst processes are dominant.…”

UDC 551. 435.4:551.435.8(460.13) Rosa Blanca González-Gutiérrez, Javier Santos-González, Amelia Gómez-Villar, Eduardo Alonso-Herrero, Alipio García-de Celis, Martín Cano & José María Redondo-Vega: Glaciokarst landforms in the Siera de los Grajos, Babia and Luna natural park (Cantabrian Mountains, NW Spain) Landforms resulting from the interaction between paleo-glaciers and karst are studied by using the Sierra de los Grajos (Cantabrian Mountains) as a model. This area contains glacial landforms that have not interested geomorphologists due to their low altitude (Peña Castillo is about 1857 m a.s.l.), the absence of glacial cirques and the scarcity of large moraines. However, the prevalence of groundwater flow and chemical dissolution has favoured the preservation of glacial landforms. Lateral and frontal moraines show three main glacial stages and other minor glacier stabilization phases, with the paleo-ELA oscillating between 1650 and 1760 m. Moraines are combined with depressions and sinks resulting from subglacial karstic drainage. This convergence of forms and processes is an exception in the Cantabrian Mountains, where postglacial erosion has usually eroded the frontal moraines and the proglacial sediments. In the case of the Sierra de los Grajos, despite the underground drainage and preservation of many glacial deposits on karstic landforms, an outwash-plain was formed. These proglacial sediments and others from non-karstified areas filled the depressions of the preglacial terrain located at their edges. The main glaciokarstic landforms have been mapped and a sedimentological analysis of the outwash plain was made in order to reconstruct the glacial dynamics of this area. Key words: glaciokarst landforms, glacial geomorphology, karst geomorphology, geomorphological mapping, Cantabrian Mountains.

Zaradi nizke nadmorske višine (Peña Castillo je le 1857 m nad morjem) ter odsotnosti velikih moren in krnic to območje geomorfologov do sedaj ni posebej zanimalo. Prav kraški procesi in z njimi povezano podzemno odtekanje so tu omogočili ohranitev ledeniških oblik. Bočne in čelne morene kažejo na tri glavne faze poledenitev in več manjših faz stabilizacije ledenikov z ravnovesno mejo (ELA) med 1650 in 1760 m.n.m. Morene so pogosto vezane na kraške globeli. Glaciokraške pojave najdemo le na tem območju Kantabrijskega gorovja, kjer je sicer poledeniška erozija odstranila čelne morene in proglacialne sedimente. Kljub podzemnemu odtoku in ohranitvi številnih ledeniških sedimentov na kraškem reliefu se je na Sierra de los Grajos oblikoval predle...

“…Some authors [44,46,53] have suggested that the differences observed between the age of the LGM and LLGM may be associated with dating techniques and the possible inclusion of dating errors. In this work, the ages obtained from the tills through OSL dating using large multigrain aliquots could present the problem of the ages being overestimated due to incomplete bleaching of sediments at deposition, as has been suggested on some occasions [65,66].…”

These studies provide growing evidence for the asynchronicity of their glacial maxima with respect to the maximum extent of the European Ice Sheet.…”

Pleistocene glacial morphology and timing of last glacial cycle in cantabrian mountains (Northern Spain): new chronological data from the Asón area

Abstract:The timing of the local last glacial maximum in the mountains of the Northern Iberian Peninsula is not synchronous with the global Last Glacial Maximum (LGM) probably due to the marginal position of the Northern Iberian Peninsula within the European continent. The study of a Cantabrian massif, the Asón platform and summits, provides new data on the extent and timing of the local last glaciation. Here we can place the last maximal extent of glaciers during Early Würm, according to OSL dating on till samples. The main glaciers developed at least between 78-65 ka BP, well centred on MIS 4 and even the transition to MIS 5. The erosive efficacy of these glaciers decreased later, ca. 45-40 ka BP, until they abruptly disappeared from the edges of the massif. A new ice advance left welldefined moraines at the edges of the massif's internal depressions, indicating a tongue disjunction phase with two glacier sub-stages, probably one at the beginning of the cooling ca. 27-25 ka BP, followed by a retreat and another glacial advance ca. 21-18 ka BP. After these episodes the glaciers disappeared from the Asón Mountains and only some residual glaciers were formed that may be related to the LGM.

“…Entre los trabajos más recientes, se pueden destacar, entre otros, algunos análisis sobre circos (Ruiz-Fernández et al, 2009;Gómez-Villar et al, 2015), sobre depósitos glaciares (Santos-González et al, 2013b), la altitud de la línea de equilibro glaciar (Serrano Cañadas y González Trueba, 2004;Santos-González et al, 2013a) o sobre la cronología glaciar (García-Ruiz et al, 2010;Jalut et al, 2010;Frochoso et al, 2013;Jiménez-Sánchez et al, 2013;Moreno et al, 2010;Serrano et al, 2013;Rodríguez-Rodríguez et al, 2015;Ruiz-Fernández et al, 2016). A pesar de esos esfuerzos, lo cierto es que aún quedan muchos valles que apenas han sido analizados en detalle y en otros muchos no se conocen con precisión los límites que alcanzó la glaciación.…”
