Hartoušovské mofety, Natural geological formation in Nebanice, Czech Republic.
The Hartousov mofettes consist of gas vents along the Plesna River, where carbon dioxide bubbles emerge through water-saturated soil.
The site gained recognition in 1958 when exploratory drilling confirmed substantial carbon dioxide flows from deep underground geological formations.
Local geologists and environmental groups monitor these formations to study the post-volcanic activity in the Cheb region of Western Bohemia.
Wooden boardwalks enable visitors to observe the gas vents safely, with information panels explaining the geological processes in multiple languages.
The gases escaping from these mofettes contain 99.5 percent carbon dioxide, originating from depths of several kilometers beneath the Earth's surface.
