The Iberian Parameras display a geodiverse tapestry that tells the richness of their natural history. From the imposing lagoons that paint the landscape, such as the Gallocanta Lagoon and Zaida, to the majestic mountain ranges that intersperse the moors, such as the Caldereros, Aragoncillo and Menera mountain rangesThese lands reveal a geological complexity that invites exploration.
This complexity and geological diversity is reflected in the integration of a large part of this territory into the Geopark of the Molina and Alto Tajo Region.
SAWS
The mountains of Aragoncillo, Boilermakers and Menera, located in the province of Guadalajara, invite you on a fascinating journey through geological time. Its imposing landscapes, the result of millions of years of formation, are home to a rich variety of rocks, fossils and formations that tell the history of our planet.
Sierra Menera: A stone giant that divides the waters
This mountain range, with its 25 kilometers in length, stands like a stone giant that decides whether its waters will flow into the Mediterranean Sea or the Atlantic Ocean. Inside are hidden the secrets of the Alpine Orogeny, a colossal event that millions of years ago gave rise to the Iberian Mountain Range. On its slopes we find Paleozoic rocks, witnesses of a remote past, when life on Earth was just beginning.
Sierra de Aragoncillo: A forest petrified in time
An invaluable treasure is found in this mountain range: a fossil forest of the Paleozoic period. Its petrified trunks transport us to a time when Pangea, the supercontinent, was a reality. The mountains also offer us slate, quartzite and limestone.
Sierra de Caldereros: A spectacle of colors and shapes
The crests of this mountain range are crowned with unique rock formations known as tormagales or towers. Its dark reddish colors contrast with the green of the pine forest and the ocher of the melojar in autumn, creating a unique visual spectacle. The sandstones that make them up are the result of erosion and sedimentation over thousands of years.

STONE AND MESA SICKLES
The rivers Table and Stone, like natural sculptors, have modeled canyons and valleys in the middle of the wastelands. Its waters meander through the highlands, creating landscapes that narrate the geological history of the Iberian Parameras. Exploring these currents is embarking on a journey through the capricious shapes that the water has sculpted in the stone over the centuries.

LAGOONS, A MIRROR OF THE STEPPE
Exploring the numerous lagoons that dot the moorland reveals ecological sanctuaries for waterfowl, where life flourishes in harmony with nature. These places, in many cases, with their pristine environment, add a symphony of biodiversity to this natural setting. To immerse yourself in these wetlands is to immerse yourself in a world of fascinating visual splendor.


GALLOCANTA LAGOON
The Gallocanta Lagoon, located between the provinces of Teruel and Zaragoza, is an endorheic wetland of singular beauty and great ecological importance. With a surface area of 14.4 km² and an average depth of 45-50 cm, the lagoon becomes a vital oasis for a wide variety of migratory birds.
The lagoon is located at the bottom of an ancient polje, a large karst depression that originated at the end of the Tertiary Era and developed during the Quaternary Era. This geological formation is characterized by an elongated, closed, flat-bottomed valley, with irregular contours that, when flooded, gave rise to the lagoon.
The land surrounding the lagoon is composed of karst materials, mainly limestone and dolomite, which are permeable and allow water infiltration. This water filters into underground aquifers, which in turn feed the lagoon from underground.
