Gredos waterfalls

Out in the open air, we touch the soft moss, the smooth polished stone, the ferns and Venus navels that grow in the cracks where threads of water trickle... In little more than a century, we have changed the Earth's skin a bit with our mines, highways, cities, and stuff. Other empires also dissolved mountains … Continue reading Gredos waterfalls

Miguel Vacas Mine. Genesis of copper mineralizations

From a geological point of view, the mineral phases that we can find in Miguel Vacas Mine are the classic ones of primary and secondary origin associated with low-temperature hydrothermal vein deposits. These are very likely related to late hydrothermal magmatic fluid circulation processes through the cracks and fissures of pre-existing metamorphic rocks (forming breccias … Continue reading Miguel Vacas Mine.

Scuba diving in Cabo de Gata

The crystal-clear waters and strong Mediterranean light allow for a view of the rock and sand bottoms, their green and turquoise colors, and the intense blue of the posidonia beds. Feeling them makes my mind dive into a sea that witnessed the birth of history. Those who brought the fluid of several civilizations sailed these … Continue reading Scuba diving in Cabo de Gata

Changes in the physical environment, such as sequences of different types of weather … Continue reading Phenology

Reaching the end of the river

Walking along a deserted beach on a Caribbean island brings real images to those exotic landscapes from movies that we could only imagine during our formative years. After seeing so many images, they somehow feel familiar to us, but we knew they were very far away. When, after a fantastic meander where the Limon River … Continue reading Reaching the end of the river

Relict oaks

More than a million years ago, the Günz glaciation occurred, followed by the Mindel glaciation half a million years ago, the Riss glaciation two hundred thousand years ago, and the Würm glaciation eighty thousand years ago. Kilometers of ice rose and fell in slow tides, changing the landscapes and what could live in this inhospitable … Continue reading Relict oaks

Management of the natural environment and wildfires

Water is very clever and flows where it costs less; with time as its ally, it erodes and destroys everything in its path with the sole aim of reaching lakes and oceans quickly and comfortably. The landscape knows water and the rest of the elements very well; they have all worked together for millions of … Continue reading Management of the natural environment and wildfires

River mirage

At times, the emptying of reservoirs reveals submerged towns, the remains of rural shipwrecks in the form of ruined mansions, mills, fulling mills, bridges, or drowned forests. However, that deceptive drought, that threatening emptiness, shows us the river that was, with gentle or tumultuous currents, clear waters, and curious fish. In that brief space between … Continue reading River mirage
