Human activities play a key role in landscape evolution. Mining is one of the most important of these since it changes large parts of the Earth’s surface. In abandoned mines and quarries, pit lakes are quite common due to water table blocking. These lakes have remarkable ecological characteristics, but they are still poorly understood. Northwestern...

Los datos muestran una temperatu...
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....
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...
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...
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...
p>The structure of the property in Leon's coal mining is based on the existence of smalle mines, a fact that makes the mining space a very fragmented one.
This charasteristic, which is a historial fact in the beginning of the coal mining, has developed slowly theroughout the last decades towards a concentration of the properties, with a small numb...
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...
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...
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...
Till macrofabric and grain size analysis of glacial diamictons present in several valleys of the Northern Serra do Gerês Mountains in the Iberian Peninsula northwest were used to interpret till types and to reconstruct the glacial paleoprocess history of this mountainous region. Slope deposits, subglacial deformation and supraglacial melt-out tills...
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...
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...
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...

We studied 15 representative types of mining activity in the Sil River basin (León province), including three types of mineral resources: gravel, roofing slate and coal. We use colour orthopothos of 2014 to calculate areas occupied by dumps, lagoons, open pi...
Our study analyses the current status of the Biosphere Reserves on the Cantabrian Mountains, especially the relationships that they have with other Protected Natural Areas with which very often coincide. These relationships concerns management bodies and one of their main problems that has to do with their negative demographic dynamic that has led...
Los bloques aradores son una de las formas periglaciares más características de las montañas ibéricas, pero los estudios específicos sobre los mismos son muy escasos. En este trabajo se presentan datos de medio centenar de bloques de dos enclaves del noroeste ibérico: el Alto Sil (Cordillera Cantábrica) y el macizo de Vizcodillo (Sierra de la Cabre...
Approximately 180 relict lobate and tongue-shaped rock glaciers are widespread in the Cantabrian Mountains, indicating past permafrost distribution in these mid-latitude mountains. They ere primarily located within glacial cirques, facing north and northeas, at the foot of quarzites and sandstones escarpments and over 1600 m, with some exceptions....
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...
A total of 156 glacial cirques located on two different areas in the Cantabrian Mountains (NW Spain) were identified and measured in order to continue and expand the study of these large-scale erosional forms in European mountains. Environmental variables that may explain cirque distribution (altitude, aspect and lithology), and their most importan...
The combined usage of till-fabric and grain-size analysis in the sedimentological interpretation of glacial diamictons allows the reconstruction of the processes responsible for the genesis of certain moraines.
