Czechs discovered the largest underground thermal lake in the world.

Czech scientists have discovered the largest underground thermal lake in the world in southern Albania and named it Neuron in honor of the foundation that funded the expedition.

After several years of research in the mountain valleys along the border between Greece and Albania, Czech scientists uncovered an extensive cave system on the Albanian side of the border and mapped it.

They found voids over a hundred meters deep, which they named Atmos.

The Neuron lake measures 138.3 meters in length and 42 meters in width.

It contains 8,335 cubic meters of thermal mineral water, making it the largest in the world.

To reach the lake, scientists had to descend 127 meters.

Such caves and lakes are formed under the influence of a process where an oil field lies beneath them several kilometers down.

Thermal waters saturated with gas or hydrogen sulfide rise to the surface and release hydrogen sulfide upon reaching the air, which transforms into sulfuric acid.

To map the cave system and discover the lake, scientists used technical equipment that was purchased thanks to funding from the Neuron Foundation.

This Czech organization provided nearly a million crowns for the expedition, which were donated by private benefactors.

The study of the Neuron lake has attracted the attention of scientific institutions from abroad, and botanist Michaela Wipplinger discovered a new species of cyanobacteria in this lake and is currently working on a scientific article.
