The „Elfer“ – home mountain of Neustift – has not only been a natural time marker for the locals since time immemorial but also shows unique geological features. It is impressive to watch how two different rock forms meet there: on the one side the rugged and bright rock towers on the Serles ridge made out of limestone, on the other side the prehistoric rock of the Stubai mountains, the so called Ötztal-Stubai-Crystalline that forms the socket of the mountain.
