estanys

Estanys are a type of natural water body found in the Pyrenees mountain range, particularly in Catalonia, Spain. They are characterized by their unique geological formation, which involves the presence of a layer of impermeable rock, such as clay or schist, that prevents water from seeping through. This layer is typically covered by a layer of permeable rock, like sandstone or limestone, which allows water to accumulate above it. The result is a large, shallow body of water, often with a diameter of several meters, that can persist for long periods, sometimes even years.

Estanys are formed through a process known as perched water, where water is trapped above an impermeable layer and cannot drain away. They are often found in areas with high rainfall and steep terrain, which contribute to the accumulation of water. Estanys can vary in size and depth, but they are typically shallow and have a relatively flat bottom.

These water bodies are of ecological significance, as they provide habitats for various plant and animal species. They also play a role in the local water cycle and can influence the surrounding landscape. Estanys are a unique and fascinating feature of the Pyrenees, and their formation and characteristics continue to be studied by geologists and environmental scientists.
