“…The Forcadona buried ice patch constitutes the contemporary remnant of a cirque glacier that existed in the area during the Little Ice Age (LIA). During the LIA the Picos de Europa concentrated six glaciers, three of which were distributed in the Western Massif (González-Trueba, 2005, 2006González-Trueba et al, 2008).…”

“…3). The area remained almost snow-free at the end of the summer of 2003, being described as a stratified ice body showing no movement (González-Trueba, 2005, 2006González-Trueba et al, 2008). The frozen body is protected from direct solar radiation by a debris cover distributed across the bottom of the glaciokarst depression.…”

“…The observations carried out between 2006 and 2011 in the Forcadona area, one of the few sites in the Cantabrian Mountain which held a glacier during the LIA (González-Trueba, 2005, 2006González-Trueba et al, 2008), has shown evidence that seasonal frost conditions are widespread today in the high lands of the massif. The presence of ground ice during several months per year together with high moisture conditions explains the intensity of periglacial processes in the Forcadona area and other high lands of the Picos de Europa (Castañón and Frochoso, 1998;Serrano and González-Trueba, 2004;González-Trueba, 2007a;Ruiz-Fernández et al, 2014).…”

“…Research on the ground thermal regime in Iberian mountains has been intense during the last years in the highest mountains ranges. Permafrost conditions have been only detected in the highest areas in the Pyrenees (Serrano et al, 2001(Serrano et al, , 2006Lugon et al, 2004;González García et al, 2016), as well as in Sierra Nevada where permafrost is spatially limited to the areas which hosted a glacier during the Little Ice Age (Gómez-Ortiz et al, 2014;Oliva et al, 2016aOliva et al, , 2016b. In other mountain environments seasonal frost conditions have been detected, as it is the case of the Galician ranges (Carrera and Valcárcel, 2010), Iberian Central Range (Andrés and Palacios, 2010) or Serra da Estrela (Vieira et al, 2003).…”

“…In the case of the Cantabrian Mountains, there has been a substantial advance on the knowledge of present-day periglacial dynamics over the last decades (e.g. Frochoso, 1994, 1998;González-Gutiérrez, 2002;Serrano and González-Trueba, 2004;González-Trueba, 2007a;Rodríguez-Pérez, 1995, 2009Santos-González, 2010;Pellitero, 2012;Ruiz-Fernández, 2013;Ruiz-Fernández et al, 2014). However, only a few studies have examined the relationship between the geomorphological setting and morphoclimatic conditions in the area (Castañón and Frochoso, 1998;Santos-González et al, 2009;González-Trueba and Serrano, 2010;Pellitero, 2012;Ruiz-Fernández et al, 2014;Pisabarro et al, 2015).…”

The present study focuses on the analysis of the ground and near-rock surface air thermal conditions at the Forcadona glacial cirque (2227 m a.s.l.) located in the Western Massif of the Picos de Europa, Spain. Temperatures have been monitored in three distinct geomorphological and topographical sites in the Forcadona area over the period 2006-11. The Forcadona buried ice patch is the remnant of a Little Ice Age glacier located in the bottom of a glacial cirque. Its location in a deep cirque determines abundant snow accumulation, with snow cover between 8 and 12 months. The presence of snow favours stable soil temperatures and geomorphic stability. Similarly to other Cantabrian Mountains, the annual thermal regime of the soil is defined by two seasonal periods (continuous thaw with daily oscillations and isothermal regime), as well as two short transition periods. However, the results showed evidence of a significantly different annual thermal regime at the ground and near-rock surface air. Relatively stable soil thermal regimes were observed at the moraine and talus sites, while a more dynamic pattern was recorded at the rock wall site. Here, a higher interannual variability in the number of freeze-thaw days was also detected, which showed evidence of the important role of the snow cover as a ground surface insulator in the area. Seasonal frost conditions are widespread today in the high lands of the massif. No permafrost regime was detected in the area, though mean temperatures measured at 0.5 m depth at the Forcadona buried ice patch during 2006-07 (0.1°C) suggest that permanent negative values may be reached at deeper layers.

The periglacial belt is located in the highest parts of temperate mountains. The balance between mean air and ground temperatures and the presence of water determine the effectiveness of periglacial processes related to permafrost, the active layer or seasonally frozen ground (SFG). This study combines thermal and geomorphological data obtained in four Pyrenean massifs (Infierno‐Argualas, Posets, Maladeta and Monte Perdido) to improve knowledge on the occurrence and distribution of frozen ground. The methodology used is based on the study of landforms as frozen ground indicators, mapping processes, ground temperature analysis, basal temperature of snow, thermal mapping and geomatic surveys on rock glaciers and protalus lobes. In the Pyrenean high mountain areas the lower limit of frozen ground is at ~2,650m a.s.l., possible permafrost appears above 2,650m a.s.l. on north‐ and south‐facing slopes, and probable permafrost is dominant above 2,900m a.s.l. Unfrozen ground with cold‐associated geomorphological processes reach 2,900m a.s.l. and unfrozen and frozen ground distribution points to a patchy pattern throughout the periglacial belt. The most widespread frozen grounds are SFG. The thermal data, mean annual ground temperature, cold season temperatures, bottom temperature snow measurements, freeze/thaw cycles and distribution of landforms permit the establishment of a periglacial land system divided into three main belts: infraperiglacial, middle periglacial and supraperiglacial. The large number of processes and landforms that are involved and their altitudinal and spatial organization make up a complex environment that determines the geoecological dynamics of high mountain areas.
