The described mofetta of CO2 is located in the Sądecki Beskid Mts, within the Poprad Landscape Park in Tylicz near Krynica, where it can be found on the SE slope of the Szalone hill, between the Syhowny and Bradowiec streams, the rightbank tributaries of the Muszynka Stream. The mouth of the mofetta, whose coordinates are: longitude 21o00'20”E, latitude 49o23’25’’N, and altitude 577 m a.s.l., is currently situated within a private holiday center. Geologically, the mofetta is situated within the Maszkowice Sandstone Member of the Magura Formation, in the SE part of the Magura Nappe of the Outer Carpathians. In its close vicinity the tectonic-facies Krynica zone is thrusted onto the Bystrzyca zone and the thrust line is intersected by the Tylicz dislocation. The daily volume of the gas discharged is estimated at fifteen or so thousand cubic meters with CO2 being the main constituent (almost 95%), while minor constituents include N2 (3.87%), CH4 (0.62%) and O2 (0.21%). The h13C value of the CO2 of the Tylicz mofetta is -1.05% against V-PDB. The gases of the mofetta are accompanied by an outflow of the carbonated water (HCO3-Ca-Mg + CO2 type, TDS 1.8 g/dm3) from the Lis spring, where abundant gelatinous, rusty-colored deposits of iron oxyhydroxides precipitate. In the years 1962-1966 the CO2 exhaled from the mofetta was utilized in experiments on algae growing, mainly for manufacturing an algae fodder. In the year 2011 the mofetta in Tylicz was made accessible to the public

Themost beautiful Polish mofette occurs in the Sądecki (Sącz) Beskid, within the Krynica tectonic-facial zone of the Magura Unit (Inner Carpathians). It is located in the Złocki Stream upstream of the Złockie village in the Muszyna commune. The occurrence has numerous exhalations of CO2 in the valley floor and on the sides of this boggy stream as well as in the „Zatopione” and „Bulgotka” springs. It is also the site of the dry exhalation „Dychawka”. The floor of the valley is covered with gelatinous rusty-brown deposits of iron oxyhydroxides that precipitate either due to chemical or organic processes (the latter initiated by numerous microorganisms, mainly ferruginous bacteria). The site is legally protected as the Professor Henryk Świdziński monument of inanimate nature. In September 2005 it was made accessible for tourists and currently is an important geological attraction in the Popradzki Landscape Park.
