El Ventanón: an impressive natural bridge

A fantastic vista through a natural window.

INTRODUCTION

"El Ventanón" is a natural bridge carved into a limestone ridge. The geological origin must be sought into the fact that water streams often sink into gaps which are located close to the edge of a limestone plateau. When such a stream dissolves a lot of limestone it can form a short but very large cave. The "El Ventanón" bridge is what remains of the roof of such a cave. The stream literally flowed below the bridge. The bridge of "El Ventanón" has a length of 30 meters and a height of 20 meters and is several meters wide. On the left side of the bridge we have found some small caves, which is an additional indication of a solutional cavernous origin of this bridge.
This geological phenomenon is included in a local walking route called the PRC-BU 32, which starts at the Ojo Guareña cave. Part of his cave, with a total length of more than 110 kilometers (110,000 meters) of galleries is one of the longest caves of Spain, can also be visited as a show cave.

When the sea attacks the coast.

In recent months the northern coast of Spain has been " shaken " five times by towering waves (red alert warnings). Apart from the damage to buildings which in general have been erected too close to the shoreline (not much fun for the people involved), it also offered an unusual spectacle of nature. Red alert is given when waves reach a mean height of about 8 meters, but two of the storms had waves with a mean of 12 meters, which means that occasionally there are waves of more than 22 meters, often arriving  in "wave trains". The following video is a summary of the last storm of March 3. This storm was of a 12 meter waves quality and with a special addition of arriving just when there was a spring tide at the highest point. As a result, the water depth increased by several meters so that also be the big waves could come much closer to the shoreline before breaking, often hitting the limestone  cliffs with full force.

The Liebana, a Mediterranean valley in the middle of the Cantabrian Mountains

These days its quite cold on the northern Spanish Meseta and the Cantabrian Mountains. However, in the heart of these mountains there exists a low-lying valley that is completely surrounded by high mountains, with a difference in topography of almost 2500 meter. This valley is called the Liebana and lies at the foot of the Picos de Europa, a limestone mountain range that already in 1918 was proclaimed the first national park of Spain. The surrounding mountains keep the wind and rain away, while the low altitude is very beneficial to the average temperature. The Liebana is blessed with a Mediterranean climate, which is unique for the Cantabrian Mountains, which is also clearly evident in its vegetation.

The bufones of the Asturian coast (Spain)

As promised in the previous post, the turn is now to the bufones of the Asturian coast. Because of the rain and splashing water of the waves and the bufones, most pictures failed or are of a poor quality, but I think I still have been able to make a reasonable selection. By the way, we went back last weekend with some very spectacular results, especially regarding the Bufones of Pría, but these photos will be addressed in the near future.

The bufones are holes, crevices or even small potholes that are connected to the sea through an extensive cave system which is open towards the sea. When the waves fill the caves the air inside is compressed and violently blown upwards through the fractures with a loud bellowing. So a bufón is a fracture which exhales air with great force and noise. This sound is what has given the name to the bufones because "bufar" means "el resoplar con fuerza del toro ", or "the hard and fierce snorting or bellowing of the bull". When the swell of the sea is great the bufones can be heard miles away, but also during summer and insignificant swell most bufones will blow. The big difference is that if there is a considerable swell, the bufones also expel high fountains of water. A Bufon in action is truly an amazing spectacle, and therefore it is astonishing that outside the province of Asturias it is almost an unknown phenomenon. I live only about 140 kilometers away from the bufones and in my village the bufones are practically unknown.

The snow capped valley of Oseja de Sajambre.

Last night, the 27 of Januari, I saw on the Spanish news footage of massive waves spilling over the quay of San Sebastian, located in Basque Country (Spain). Along the northern coast of Asturias there exists a long karst-landscape with a large number of bufones. A bufón is a hole in the rock which connects with the sea and which makes a lot of noise due to the waves which enter underlying cavities. But when the swell and the waves are considerable, these bufones also spray lots of water like the fountain of a gigantic whale. According to internet the waves for today were expected to be between 6 and 8 meters, which is more than enough for an impressive spectacle. So last night I tried to get over the mountain pass which lies between León and Asturias, but this was impossible because of the heavy snowfall. But this morning I tried again and using a road cleared of snow I got to the mountain pass El Pontón without problems (the Spanish are very efficient in clearing their roads). Driving down the pass the sight of the snow capped landscape and the snow covered trees was wonderful. The following pictures testify of this white beauty, except the last two pictures which give a first impression of the Bufón fountains, but these are covered in the next post .

Mountain hike to a millennial Taxus baccata tree.

Yesterday afternoon we went for a trip to visit a millennial Taxus baccata. This tree stands completely alone and isolated at the foot of some high mountain peaks. So it was quite a climb, especially since there is no clear path going to the yew. The Taxus baccata is a very poisonous yew tree, although the cattle and specially the goats sometimes eat the twigs. The only edible substance of the tree is the red flesh of the fruits, although the kernel is poisonous again. The best is to be very careful when eating the fruits or simply not eating them at all.

From Cistierna to Covadonga: Pictures of some very special places in the Cantabrian Mountains.

Introduction 

From Cistierna, a village situated on the southern edge of the Cantabrian Mountains, to Covadonga we have to cross almost the entire Cantabrian Mountain chain. The 100 km which separate both villages can be driven by car in about 2 hours, although the beauty of the landscape probably will cause a considerable delay. Yesterday we repeated this trip and in this post I want to share some pictures of some very special places we came along. These places are only a small part of the overwhelming nature which will be encountered on this trip, for instance the mountains of Crémenes, the mountain pass "El Ponton" and the huge gorge of the "Desfiladero de los Beyos" are not photographed.

How the waves form the coast.

At some places the northern border of the Cantabrian Mountains almost reaches to the Bay of Biscay, from which it is only separated by a narrow coastal plain, and one of these places is the east of Spanish province of Asturias. Here the plain consists mainly of limestone, which is a rock with the property that it is slightly soluble in water. For this reason the eternal waves of the ocean have sculpted a very particular terrain with steep cliffs and numerous sea caves. Furthermore, the whole area experiences a slow geological uplift which has caused the rising of the former sea bottom above sea level, forming the actual coastal plain between the sea and the Cantabrian Mountains.  In other words, the current plain was formed by the wave action of the sea, which reached a few kilometers further inland to the foot of the mountains. After the coastal plain was elevated, caves have formed in many places. In some of these caves beautiful prehistoric rock paintings have been found, including those of the Cueva del Pindal (Colombres) and the caves of Tito Bustillo (Ribadesella).  Before showing the pictures of the coast  I will show a few "boring" maps which indicate the exact location of where we visited the coastal plain.

This location is part of the officially protected landscape of the eastern Asturian coast (Paisaje Protegido de la Costa Oriental Asturiana), which covers a total length along the coast of about 30 kilometers and a surface of nearly 67 square kilometer.

Winter in the Cantabrian Mountains

Snow in Spain

Marius van Heiningen

Spain is known for its good weather with a lot of sunshine, which of course is true, but in the mountainous areas of the north thick layers of freshly fallen snow are quiet normal. Although on the higher and northwards orientated peaks several meters of snow can accumulate, normally the snows disappears rather quickly due to the strength of the Spanish sun, which even in winter is appreciable. This year the snowfall came at the end of January and the beginning of February, which gave me the opportunity to click the “white” photos of the following photo session. These photos serve to give a general view of the mountainous character of the Cantabrian Mountains. Of most photos mountain names and direction of view are given, with the heights and the place from which the photo is taken in parentheses.

The southern border of the Cantabrian Mounatins, as seen from the meseta of the Duero basin. The view is to the north.This mountain massif is called Peñacorada (1835m). To see the same picture full screen, click on the small photo to the right.

Tocht naar een duizendjarige venijnboom

Gistermiddag zijn we er op uitgetrokken om een 1000+ jarige venijnboom (Taxus baccata) te bezoeken. Deze boom staat geheel alleen en afgezonderd aan de voet van enkele hoge bergtoppen. Het was dus een hele klim, vooral omdat er geen duidelijk pad naar toe gaat.
Ondanks dat het vee er soms van eet, is de venijnboom toch een erg giftige boom. Alleen het rode vruchtvlees is eetbaar, maar de pit dus weer niet. Al met al is voorzichtigheid dus geboden.
