The ice holes are a basin-like, about 200 m long and 5-10 m wide hollow at the foot of the landslide on Gantkofel. Through a wind tunnel system in the mountain, cold air flows with 0 ° C to a maximum of 5 ° C in the boiler and forms a cold air lake, which does not dissolve even in the summer months. So it can happen that you sweat in the only 500 meters away orchards at 30 ° C, while at the bottom of the ice holes has supercooled 5 ° C.

The ice holes on the Gandberg between Appiano and Caldaro in South Tyrol are local cold-air areas in which the temperature differs significantly from the generally common in the region. The phenomenon is explained by the physical principle of the wind tunnel (also known as convective air movement in caving).

The ice holes are depressions where cold air gathers, so even in hot summers until the end of September ice is found. Due to the special location, you will find plants that otherwise thrive only in much higher elevations. So the biodiversity among the plants is particularly high here.
