Lake Habicher See belongs to the Achstürze-Piburg landscape conservation area. The entire region can look back on a millennia-old history. At that time Ötztal also was the scene of rockslides in all dimensions. Four of them were big enough to block the whole valley and dam up Ötztaler Ache mountain brook. As a result we can still see the five valley terraces. The steeper sections in between consist of huge landslide masses, through which the Ache brook made its way across the valley - resulting in a number of smaller waters and basins. Splendid lake Habicher See belongs to the last remains of this so-called "chain of lakes".
