Abano Mineral Lake

The lake was formed by the influence of an underground carbon dioxide flow that penetrates the surface through carbonate rocks of the late Jurassic era. The surface of the lake is constantly "boiling" with escaping gas bubbles, creating a picturesque spectacle. The daily flow rate of the stream feeding the lake is a huge 2.5 million liters of water. The total surface area of the lake is small - only 0.04 hectares. In calm weather, the carbon dioxide emission can accumulate at lower levels, posing a danger to small animals. As they approach the lake, they can suffocate from excess gas, which explains the presence of dead mice, lizards, frogs, and some birds in the vicinity.
