 Is a spectacular pothole, with a 35 m diameter entrance. At the basis of the vertical entrance (of -38 m deep), there is a large block of permanent ice, 16 m deep.
The pothole has a total length of 150 m and a depth of 54 m obtained due to a short gallery which gives access to a large hall. The pothole is situated above the subterranean route of the Fortress of Ponor underground river, but the access is blocked by the ice. The ice block is estimated to have about 30 000 m3 in volume, being the second largest in the country, after the Scărişoara ice cave, also situated in the Apuseni Nature Park. |
