In a corrie or cirque, the bergschrund is positioned at the rear, parallel to the back wall of the corrie.
Paternosters occur in alpine valleys, climbing one after the other to the valley's head, called a corrie, which often contains a cirque lake.
This is a classic corrie tarn, held in by a whalebacked moraine and having a depth of around 60 ft.
It harboured a number of corrie glaciers, most of which are now occupied by loughs.
This corrie tarn, held in place by grassy moraines is around 65 ft deep.
The summit stands on the edge of the cliffs overlooking the corrie.
The tarn is a water filled corrie about 50 ft deep, this being enhanced by a dam.
It has been claimed that this corrie may have contained a glacier as recently as the 18th century.
