The Wilde Gerlos creek originates from the terminus of the Reichenspitze glacier in the Hohe Tauern of the Austrian Alps. It runs within a deep narrow gorge that was carved out by water erosion into the hanging valley that formed during the last ice-age. The exposed rocks are highly metamorph. During the mountain uplifting processes they were molten and chemically rearranged by high pressure and temperatures deep within the Earths crust. They are rare relics of an ancient volcanic sea-floor. These greenstone series of the former Tethys ocean are now exposed at about 2000 m altitude.
