A cirque may also be a similarly shaped landform arising from fluvial erosion. The concave shape of a glacial cirque is open on the downhill side, while the cupped section is generally steep. Cliff-like slopes, down which ice and glaciated debris combine and converge, form the three or more higher sides.
Headwall and corrie lake Cwm Idwal. In physical geography and geology, the headwall of a glacial cirque is its highest cliff.The term has been more broadly used to describe similar geomorphic features of non-glacial origin consisting of a concave depression with convergent slopes typically of 65 percent or greater forming the upper end of a drainage valley.
Bight – Shallowly concave bend or curve in a coastline, river, or other geographical feature; Blowhole – Hole at the top of a sea-cave which allows waves to force water or spray out of the hole; Blowout – Depressions in a sand dune ecosystem caused by the removal of sediments by wind; Bluff – Tall, near vertical rock face
A cirque is an amphitheatre-like valley formed at the head of a glacier by erosion. Subcategories. This category has the following 4 subcategories, out of 4 total. ...
A cirque stairway or sequence of cirque steps is a stepped succession of glacially eroded rock basins. [1] 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 ...
The podium of the spina has a concave shape at the end. [13] The meta prima was located in the lacuna present on the work. [13] In addition to the insured elements, the spina included a round temple and "one or two elements", perhaps a chapel and a monumental column. [43] [41] The spina was richly decorated with statues.

The Cirque de Gavarnie (French pronunciation: [siʁk də ɡavaʁni]) is a cirque in the central Pyrenees, in Southwestern France, close to the border of Spain. It is within the commune of Gavarnie , the department of Hautes-Pyrénées , and the Pyrénées National Park .
The concave bank is often a cut bank and an area of erosion. The eroded material is swept and rolled across the floor of the stream by the secondary flow and may be deposited on the point bar only a small distance downstream from its original location in the concave bank. The point bar typically has a gently sloping floor with shallow water.
