Segmann - Salzach glacier

---

At the peak of the Würm ice age, 24-22,000 years ago, around 150,000 sq. km. of the Alps and foothills were covered in ice. The valleys and were filled with ice up to 2,000 m thick, such as the Inn glacier, Salzach glacier and Traun glacier.

At the peak of the Würm ice age, the Salzach glacier covered an area of 6,8000 sq. km. The boundaries of the catchment area were formed by the Gerlos pass in the west, the main alpine ridge in the south, and the Wagrainer pass in the east. From the catchment area, the north slope of the Hohe Tauern, ice streams followed the Tauern valleys, joined together in the Salzach valley and flowed northward through this region and the Saalach valley. In the area of the Ore of the Alps UNESCO Global Geopark, the upper limit of the ice was 2,000; in the area of the city of Salzburg, it was 1,000.

The two ice streams merged in the Salzburg Basin, in the area of the city of Salzburg. From here, the ice masses formed a common foreland glacier (Piedmont glacier) in the Salzburg-Bavarian border area. This fanned out into several glacial branches, the edges of which encompassed terminal moraines. The interior of the branch basin is still characterized today by a gently undulating ground moraine landscape.
