Water from the Spring

Groundwater is stored in locations where it is maintained at a constant temperature and in a disposition similar to the surface topography of the area where it is found. These locations, called aquifers, are geological formations formed by successions of layers of porous and impermeable materials in which freshwater is housed underground. The porosity of … Continue reading Water from the Spring

Small Silurus

In the seventies of the twentieth century, the German tourist Roland Lorkowsky brought thirty-two Danube catfish fry in a jug, which he later released into the mouth of the Segre River so that they "could grow and multiply" in the reservoirs of Mequinenza and Ribarroja. Before him, the nature protection service ICONA had released all … Continue reading Small Silurus

The Stone Powers

To be honest, I have to confess that I don't believe in any powers that stones transmit beyond awakening aesthetic taste, the pleasure of giving them as a gift, or, in a more perverse realm, fostering greed. Undoubtedly, my approach to mineral collecting belongs to both the realm of wonder and beauty, but what I … Continue reading The Stone Powers

Aragonites and salt pans

On the way to search for aragonites, we discovered an old factory, its large wells, the labyrinth of pools and walls in the middle of the wasteland, near a deserted village. Few things abound so much in the world, just a little bit of ocean and a little bit of sun for it to precipitate, … Continue reading Aragonites and salt pans

Searching for weightlessness

Minutes I have been fascinated by the depths of the sea since before I knew how to use my consciousness. As a child, I began visiting them. The Mediterranean was where I discovered those pristine and, at that time, little-traveled bottoms in the 70s. All you needed was a snorkel and fins, approach the rocks … Continue reading Searching for weightlessness

Garganta de Cuartos oaks

On December 10, 1997, a large logging company was cutting down 1000-year-old sequoias. Julia "Butterfly" Hill climbed one of them and stayed up there for 738 days, enduring the company's harassment and even a hurricane. In this way, she managed to make her gesture known to many and finally prevented their felling. These oak forests … Continue reading Garganta de Cuartos oaks
