El análisis de la cubierta de nieve es de especial importancia en el estudio del clima de entornos de alta montaña, donde la topografía local influye notablemente sobre los registros climáticos, siendo uno de los principales condicionantes del régimen térmico del suelo, que resulta fundamental en el desarrollo de diversos procesos geomorfológicos....

Over the last few decades, environmental changes have occurred in the Cantabrian Mountains (Northwest Spain) as a result of economic, social and climatic transformations. The depopulation in the rural environment with the transformation of traditional land uses, the closure of coal mining operations, and the increase in temperatures have modified t...
Conference Paper
The Schmidt-hammer has been used in Geomorphology for the last decades. The effectiveness of the method has been proven by several authors, but some limitations also exists. In this work, this procedure has been tested in glacial and periglacial landforms in five different massifs in the province of León (northwestern Spain): Vizcodillo, Arcos del...
Article
Till macrofabric and grain-size analysis of glacial diamictons and landforms present in several valleys of the Serra da Estrela Mountains in central Portugal were used to interpret till types and to reconstruct the glacial paleoprocess history of this mountainous region. Supraglacial melt-out and flow tills are dominant in this range. Supraglacial...

Air and near-surface ground temperatures were measured using dataloggers over 14 years (2006-2020) in 10 locations at 2262 to 2471 m.a.s.l. in a glacial cirque of the Cantabrian Mountains. These sites exhibit relevant differences in terms of substrate, solar radiation, orientation, and geomorphology. Basal temperature of snow (BTS) measurements and...

During the Late Pleistocene, the main mountain ranges of the Iberian Peninsula were covered by small icefields and cirque and alpine glaciers. The deglaciation triggered paraglacial processes that generated landforms, mostly within the ice-free glacial cirques. In this research we analyse the deglaciation process in the Muxivén Cirque (42°15′N – 6°...

The Montes de León (northwest Spain) include the Aquilanos Mountains (2142 m), the Teleno Mountains (2182 m), and the Sierra de la Cabrera (2121 m), which are Paleozoic mountains with a predominance of slate and quartzite. During the maximum glacial advance, 94 small cirque and valley glaciers (up to 9 km long) occupying c. 116 km² were formed in t...

Knowledge about the glacial geomorphology in the Leonese Cantabrian Mountains is synthesized in this chapter. After the Pyrenees, the Leonese Cantabrian Mountains hosted the largest glaciers in Iberia, with an ice surface extent exceeding 1200 km² and 22 glaciers with ice tongues >10 km. The largest glacier complexes developed in the valleys of the...

Mining activity introduces severe changes in landscapes and, subsequently, in land uses. One of the most singular changes is the existence of pit lakes, which occur in active and, more frequently, abandoned mines. Pit lakes are produced by water table interception when open-pit mines deepen. Their characteristics are highly variable, depending on t...
Conference Paper
ABSTRACT The open pit mines produce drastic changes in the relief and in the landscapes where they are located. These changes depend on the size of the exploitations, the exploitation systems and the type of mineral extracted. The gold mining carried out by the Romans in the province of León required the mobilization of large volumes of rock to ext...

Dam-failure floods typically involve greater peak discharge than the largest meteorological flood at a basin. Determining the geomorphic effectiveness of extreme flooding caused by a breach mechanism provides insight into the role of flood scale on the resulting processes and landforms. Here, we present a geomorphological and hydraulic analysis of...

The objective of this study was to assess whether it is possible to obtain a comprehensive record of the last deglaciation from the small Peña Negra glacial cirque in a marginal mountain range in the Iberian Range (northern Iberian Peninsula). The cirque is located in Sierra Cebollera, at an elevation slightly over 2000 m a.s.l. in the divide, and...

An active Magellanic penguin (Spheniscus magellanicus) colony has been established on Martillo Island, Beagle Channel (54°54´26” S; 67°22´58” W) since 1976. It is located in remnants of eroded drumlins placed in both ending and joined by gravel terraces of glaciofluvial and marine origin. Forest patches occupy the eastern side of the island while m...

With an extensive and high elevation surface (1800-1900 m a.s.l.), the Sancenas karst massif (Cantabrian Mountains) was home to a small icefield developed during late Pleistocene times. Glacial and karst processes are dominant in this region, generating many glaciokarst landforms which are uncommon in the glaciated mountains of Spain. Well-preserve...
Article
Relict rock glaciers are widespread in the Cantabrian Mountains, with more than 250 lobate, tongued‐shaped and complex landforms identified. Located mostly within glacial cirques, facing north and northeast, these landforms are indicative of the distribution of ancient permafrost. Macro‐fabric analysis allows us to reconstruct the past dynamics of...

En la provincia de León existen numerosas lagunas de pequeño tamaño localizadas en diversos ámbitos geográficos. En este trabajo, se analizan los principales orígenes que explican su presencia, tanto para aquéllas que son naturales como para las de origen antrópico. Así, en las áreas de montaña son frecuentes las lagunas de origen glaciar, que pued...
Article
Deglaciated mountainous areas are usually affected by a great range of paraglacial processes that involve progressively denudation of glacial imprints. This study focuses on paraglacial processes and glacial landform preservation in six zones located in two catchments of the Cantabrian Mountains (NW Spain). These zones are adjacent but display impo...

The Demanda Sierra, at altitudes above 2000 m.a.s.l., is located in the Iberian Range (Northern Iberian Peninsula, 42º15' N). The main divide extends from west to east between 3º25' W and 2º52' W. The most relevant evidences of Pleistocene glaciation are found in small cirques above 1800 m a.s.l., most of them in the northern face. These cirques ho...

The geoconservation field has proven relevant progress in recent years. Inventorying, whether for scientific or tourist purpose, is among the most frequent actions. Although there is an increasing number of a methodological research on inventory, in many cases, it does not include accurate geosite delimitation nor management proposals. These two as...

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...

Till macrofabric and grain-size analysis of glacial diamictons and sequences present in several valleys of the Southern Serra do Gerês Mountains in the Northwestern Iberian Peninsula were used to interpret till types and to reconstruct the glacial paleoprocess history of this mountainous region. Subglacial lodgement and supraglacial melt-out tills...

In this study, fossil debris-covered glaciers are investigated and dated in the Sierra de la Demanda, northern Spain. They are located in glacial valleys of approximately 1 km in length, where several moraines represent distinct phases of the deglaciation period. Several boulders in the moraines and fossil debris-covered glaciers were selected for...

The study addresses two valleys in the river Porma basin, on the southern slope of the Cantabrian Mountains, Spain. In the first one, the Respina Valley, there are many glacial evidences, such as cirques, moraines, till or erratic boulders, demonstrating the importance of the glaciation in this valley. The second one, the Rebueno Valley, shows very...

In the Geres Mountains of the northwestern Portugal and northwestern Spain, glacial sediments existed that had been mapped and identified, but not studied sedimentologically. Therefore, the need existed for a sedimentological study. The glacial deposits are being studied using till fabric and grain size analyses. This research will determine the di...

The La Balouta Valley, located in the extreme SW region of the Las Médulas Natural Monument and UNESCO World Heritage Site (León, Spain), is one of the largest gold-mining sites developed by Romans more than 2,000 years ago when excavating a thick series of red Miocene sediments in the area. The main determining feature of the La Balouta Valley, es...
