The Zastler Loch or Zastler Cirque ( German : Zastlerkar ) on the northern side of the Feldberg summit in the Black Forest is the highest cirque in the German Central Uplands . It forms the head of the Zastler valley, through which the Zastlerbach stream flows northwards into the Dreisam .
6-468: The Zastler Loch is a cirque stairway with 3 deeply carved cirque floors: one at 1,400 metres, a heavily destroyed one at 1,320 metres and a well preserved floor at 1,250 metres; all three being linked to one another by rockfalls. The lowest floor has retained its old hollow shape and is entirely covered by bog . This bog, east of the Zastler Hut , is about 100 metres long and 40 metres across. The bog
12-562: Is 150 to 200 metres. Glacial striations may be seen on free-standing rocks around the Zastler Hut. Das Zastler Loch is the source region of the Zastlerbach stream. In winter the slopes of the cirque are prone to the formation of cornices and to avalanches . Sometimes the snow remains until well into the summer months. Around 1840, when a cold period dominated Europe, the inhabitants of the eastern and northern Feldberg region cut
18-461: Is a stepped succession of glacially eroded rock basins. Their individual formation is that of a cirque . These steps are arranged one above and behind the other at different heights in the terrain and caused by the same morphodynamic processes, albeit resulting in different landform shapes depending on the type of rock and the depositional circumstances involved. The lower step often lacks the steep headwalls typical of cirques. A well-known example
24-402: Is sealed on the right hand rock face by a 12-metre-high curved false embankment. This consists of gneiss covered by terminal moraine material. Between the bank and the rock face there is a small hollow , about two metres deep, that was probably formed by a small river of ice from the gully to the southeast. The height difference between the lower cirque step and the upper edge of the rock face
30-589: The most valuable locations within it for plant species. An initiative by members of the Black Forest Club and the Black Forest Conservation Working Party prevent plans in the 1960s for ski slopes and a gondola lift here. 47°52′35.04″N 8°0′34.92″E / 47.8764000°N 8.0097000°E / 47.8764000; 8.0097000 Cirque stairway A cirque stairway or sequence of cirque steps
36-744: The snowfield to the ground because they feared a glaciation of the Feldberg. Since 1651 there has been grazing in the Zastler Loch. The former cattle hut, the Zastler Hut is a restaurant today. Next to it is the Freiburger Hut which was built in 1952 for the Freiburg Ski Club. Charcoal burning sites may also be seen in the Zastler Loch. The Zastler Loch is part of the Feldberg Nature Reserve and forms one of
