The "ice holes" of Eppan
The question is: How it is possible that on an altitude of about 500 m above sea level there are growing alpine roses, that icy air is blowing through chinks and that in consequence you have to put on a jacket also in summer?
The explanation is quite easy and little mysterious: The freezing air results from air circulation in the inside of the rocks. Warm air enters above and becomes colder in the inside, before it exits below with a temperature of 0 to 5° C.
