Monte Santiago, the abrupt boundary between

the Spanish highland and the Basque lowland.

During the Easter holiday we managed to escape for a few days, devoting our time to

the detection of new orchid sites, exploring caves and visiting beautiful places. In thispost I want to share some pictures of the Monte Santiago Natural Park, with its 300

meters high waterfall: El salto del Ro Nervin. This blog is also dedicated to natural

spaces located in the immediate vicinity of the Cantabrian Mountains.

The location of this park is quiet special, because its the only place where the Spanish

highland (meseta) borders the coastal lowlands. Most of the northern meseta (with

heights of 800 to 900 meters) is separated from the north coast by the Cantabrian

Mountains (with altitudes of over 2000 meters). However, these mountains end some 30

kilometers west of Monte Santiago, so that in this park the meseta is directly adjacent to

the lowland of Vizcaya (Basque Country). The border between both regions consists of

a dizzying steep cliff of about 500 to 600 meters high and several tens of kilometers

long: a spectacular sight enhanced in value by the presence of numerous vulture nests.

The River Nervin collects its water on the meseta and streams towards the cliff where

it flows over the edge and plunges down. However, this 300 meter high waterfall can

only be admired during periods of heavy rain or melting snow. This is due to the karst

nature of the plateau, where most of the surface water quickly disappears below ground

into an enormous underlying cavesystem. Monte Santiago is covered with a beech forest

which is fed by rain and mist coming from the sea. Also there are the ruins of the

medieval monastery of Santiago de Langrriz, which gives its name to this natural park.

Very close to the car park we can find the ruins of the monastery from Santiago de Langreriz",

dating from the XI and XII centuries.

This pavement is not laid down by humans, it is the product of a natural karst-process whereby

the water enters the fissures and dissolves the rock.

Now we come to the edge of the meseta ......

.... we are very lucky to find the waterfall plunging down. However, given the width of the

riverbed, at certain moments the volume of water can be much bigger.

The steep wall which forms the border between the Spanish highland and the Basque lowland,

as seen from below.

The morphological route brings us back to the monastery. But where in the center of this

karstic highland did these people actually get their water?

After looking around, and very close to the monastery, we found this: a major source rising on

one side of a local depression of the landscape.

Crystal clear water is flowing over artificial dams. But. where does it go to?

...... to discover that after a short distance the stream disappears underground again. It is now

clear why the monks had their monastery just in this exact place, water is life.
