In the west of Australia there is an unusual geological object - the Volna Rock, named so for its resemblance to a huge sea wave: its height reaches 15 m, length is about 110 m. The granite rock, literally growing out of the ground, was formed about 60 million years ago. A powerful granite massif, far from resembling a wave at that time, was subjected to chemical weathering, erosion and the influence of weather conditions for millennia. Under the influence of these factors, the softer soil was gradually removed, the massif was ground, and the weathering products were washed off by water and carried away by the winds. In the end, the rock took on such an unusual shape and turned into a natural attraction popular with tourists.
A feature of The Wave, rarely seen in photographs, is the containment wall, which is built halfway to the popular site. The wall follows the contour of the rock and allows rainwater to be collected in the storage. It was built in 1951 and similar walls were erected on some other rocks, unknown because of their standard.
A similar notable geological object is located in Vermilion County (Illinois, USA). Wave (or Wave) also resembles frozen waves of the surf. But it, under the influence of the same factors listed above (weathering, erosion, weather), was formed already from sandstone. Experts suggest that the formation process fell on the times of the existence of dinosaurs, that is, in the Jurassic period.
