Pechón is a small village in Cantabria, located in Val de San Vicente council. This council is on the coastline, in the most western part of Cantabria, between Tina Menor and Tina Mayor estuaries, being the last one the limit between Cantabria and Asturias. The council is formed by 14 villages, whose city council is in Pesués, the central point of all of them.
The council has mountainous terrain. The smaller littoral mountain ranges, located between El Escudo range in Cabuérniga and the sea, define the territory. The shore is steep with cliffs and it is divided by the two estuaries, where the most western rivers of Cantabria run into, Deva River (Tina Mayor Estuary) and Nansa River (Tina Menor Estuary), which were originated by the floods in the lowest parts of the valley. Both estuaries create a landscape with lagoons so that the presence of the sea is notice some kilometers inside, like the Nansa River in Muñorrodero, or the Deva River in Molleda.
Within the council, Pechón is along the coastline between both estuaries.
The highest part, 200m over the sea level, is a flat known as El Llano, which is narrowed in the central part (El Calvario), and it is enlarged towards east (Tina Mayor) and west (Tina Menor). These parts of the flat are the ones that have named the estuaries. In the hillside of El Llano, between 90 and 60 meters over the sea level, it is located the village and crops. This part is not flat but strongly eroded.
The rocky materials of the territory around Pechón are basically limestones, marls and sandstone. Limestones, which predominate, are very permeable and they have given place to amazing landscapes called karst.
You can find examples of small rounded hollows, underground caverns or large caves, connected by an underground tunnels net.
