00:04You can see that in the Morte Resch Glacier in Pontresina.
00:08The ice caves were formed because of the melted water from the glaciers
00:12that froze again and fell into the cave.
00:15This is a rare opportunity because the ice caves are not permanent there,
00:19so hikers temporarily go there.
00:23Every winter, tourists are allowed to visit the place.
