Hartoušovské mofety

Hartoušovské mofety are gas vents located along the Plesna River where carbon dioxide emerges from underground through saturated soil and water. These formations create visible disturbances in the landscape where pressurized gases from depths escape to the surface.

Scientific confirmation of the site came in 1958 when drilling revealed massive carbon dioxide flows from deep underground formations. This discovery established the location as an important example of ongoing volcanic-related activity in the region.

The site represents a tangible connection to the region's volcanic heritage, visible in how carbon dioxide continuously rises through the landscape. Visitors can witness this ongoing geological activity that shapes the character of Western Bohemia.

Wooden boardwalks provide safe access to observe the gas vents, with information panels explaining the geological processes in several languages. The accessible paths allow visitors of all ages to walk through and understand the underground activity.

The gas escaping here is composed almost entirely of carbon dioxide sourced from several kilometers beneath the Earth's crust. This composition makes the site one of the purest natural carbon dioxide sources in the region.
