Pinnacle (geology)

[1] The rock tower was created as a result of mechanical erosion, namely the gradual breakdown and destruction of a flat plateau or a rocky mountain ridge.

[2] Its shape is the result of mechanical weathering and the attitude of the rock, or the subsidence of the slope.

They are found on the edges of high mountains and tabular plateaus, such as the buttes in arid regions, or on heavily disturbed rocky coasts.

[4] Examples are the summits of the Aiguille du Midi in the Mont Blanc massif in France, the almost 43-metre-high Barbarine on the south side of the Pfaffenstein hill near Königstein in Germany, or the Bischofsmütze, the Drei Zinnen and the Vajolet Towers in the Dolomites, which are rich in such towers.

An area of limestone formations within Nambung National Park, near the town of Cervantes, Western Australia, is known as The Pinnacles.
