Outstanding rock formations of the world
Below are listed selected rock formations of the world. These rock formations are arranged by the part of the world and in an alphabetic order:
- Aloba Arch – Chad, Ennedi. One of the most impressive natural arches of the world. Arch is 77 m wide and some 120 m tall.
- Amphitheatre in Drakensberg in KwaZulu Natal, South Africa is one of the most impressive cliff faces on Earth. This enormous cliff is over 5 kilometers long and 1,220 meters high along its entire length, the highest part of the cliff is 1,830 metres high. 948 metres high Tugela Falls fall over Amphitheatre.
- Ben Amera (Ben Amira) – Mauritania, Adrar. One of the largest monolithic masses of rock in the world, 400 m high, dark grey pyramid rising from the desert sands. Prehistoric rock art is found nearby.
- Djoula Oued Arch – Chad, Ennedi. Very delicate, seemingly impossible natural arch. 14 m wide and 32.6 m tall.
- Fish River Canyon – Namibia, Karas. Second largest canyon in the world after the Grand Canyon (United States). This giant canyon is some 160 km long, up to 27 km wide, up to 550 m deep.
- Great Tsingy de Bemaraha – Madagascar, Menabe. Unique karst landscape, consisting of thousands of rock blocks dissected by 80 – 120 m deep grikes with vertical walls. Mostly formed by collapse of caves and caverns. Sometimes these grikes are very narrow, less than 1 m and create immense impression to the one walking through them. Countless interesting karst formations, including caves, natural bridges, tufa pseudoroofs. Numerous endemic species of plants and animals – 47% of locally met species of plants and animals are found only in Tsingy de Bemaraha – for example here are 34 endemic species of reptiles.
- Manambolo River Gorge – Madagascar, Menabe. Spectacular gorge – both banks of the river are formed by giant, steep and often overhanging clifs of Bemaraha Tsingy. Numerous caves, natural bridges and other interesting karst formations.
- Pico Cão Grande – São Tomé and Príncipe. Dramatic needle-shaped volcanic plug which rises more than 300 m above its surroundings.
- Richat Structure – Mauritania, Adrar. Amazing geological formation – heavily eroded, approximately 40 km wide dome, which looks like a giant eye from the space. Although widely believed to be an impact crater, this is enormous, circular upheaval dome.
- Takouba Arch – Algeria, Illizi. Weird, impressive natural arch, some 20 m high and 10 m wide.
- Trou de Fer canyon and waterfalls – several cascades of streams in Trou de Fer – one of most magnificent slot canyons in the world. Total height of Bras de Caverne Falls is 725 m, first step is 210 m high (mostly dry), next – 180 m high and third – 300 m, several smaller steps in between. There are six more very tall waterfalls in the canyon. Lower Bras Mazerin fall is 270 m tall.
- Tsingy de Ankarana – Madagascar, Diana. Spectacular tsingy – a karst formation, where a layer of middle Jurassic limestone is dissolved by water, leaving a "forest" of limestone blades. Separate blades might be up to 20 m high. The gorges and canyons dissecting the Ankarana are up to 140 m deep. In many larger gorges and canyons exist patches of primeval tropical forest with numerous endemic species of plants and animals. Some of these forests are available only through caves – total length of explored caves in the region exceeds 100 km. Up to 6 m long Nile crocodiles live in the caves of Ankarana (mostly in River Styx – 4 km long subterranean passage passable only by a boat). This is one of the few places where crocodiles live in Madagascar (it is seen also in Belomotse Forest and some other places) and a unique case where crocodiles live in caves. Numerous fossils of the extinct Madagascaran fauna are found here.

Described rock formations of the world
This type of landmarks includes most unusual and interesting rock formations of the world.
It may sound simple but it isn’t: this group of monuments tends to grow and grow without end, encompassing diverse seemingly unrelated things. Thus – very tall cliff is rock formation, natural arch – as well. But – in a way cave and waterfall also is rock formation – without solid rock these landmarks would not exist.
Wondermondo includes in this category the following landmarks:
- Boulders – especially large or otherwise unusual fragments of rocks;
- Balancing rocks – boulders and other rock formations which seem to defy gravity;
- Cliffs – visually impressive and/or very tall natural surfaces of rocks. For most part these surfaces are vertical or very steep;
- Canyons and ravines – well, here are two natural rock surfaces, on both sides of existing or formed stream. Some canyons belong to world’s most impressive landmarks;
- Monoliths or inselbergs and bornhardts – monolithic masses of rocks which form unusual, giant relief forms, sometimes similar to giant pillows;
- Natural arches – cliff formations with openings below them. Nature sometimes loves to play and these arches or bridges can get seemingly improbable shapes!
- Rock spires – natural, tall and often even very thin spires of rocks.
This classification does not include all kinds of rock formations – sometimes a landmark is too unusual and in its own “category”. Such landmarks are, for example, Eaglehawk Neck tesselated pavement in Tasmania or Richat Structure in Mauritania.
Some recordsIt is not easy to register the records of rock formations – here the types of formations gradually shift and there are no clear limits set – what is cliff and what is just a steep rock face, what is rock pyramid and when is it narrow enough to be considered rock spire? Some records though can be measured:
- Highest vertical drop on Earth could be located on Mount Thor (Canada, Nunavut, Baffin Island). This cliff has even negative drop (105 degrees) and if something falls from it, it falls 1,250 m. There might be even taller drops in Baffin Island.
- World’s tallest near vertical cliff (you see – there is already indeterminate expression!) is Great Trango Tower in Pakistan, Gilgit Baltistan. This cliff is 1,340 m tall.
- World’s deepest canyon could be Yarlung Tsangpo Grand Canyon in Tibet, Nyingchi. It is up to 6,009 m deep, although medium depth is 2,268 m.
- World’s tallest volcanic stack is Ball’s Pyramid, Australia. It rises 562 m tall from the sea and is just 200 m wide.
- World’s highest natural arch could be Tushuk Tash (Shipton’s Arch) in China, Xinjiang Uyghur Autonomous Region. Its opening is just incredible: 360 – 370 m high!
- World’s widest natural arch could be Xian Ren Qiao – Fairy Bridge in China, Guangxi. It is approximately 122 m wide.
- World’s largest freestanding boulder could be Giant Rock in United States, California. This rounded boulder covers an area of 540 square meters.
- The largest balanced rock in the world could be Miracle Rock in United States, Colorado. This is some 12,000 tons heavy behemoth balancing on impossibly small foot.
