A stack (stacks) or seastacks is a rock formation consisting of steep vertical column or columns of stone in the sea near a beach. They are formed when part of a headland is eroded by water hitting the rocks or as a result of wind erosion. This impressive complex formations created by nature through time, tide and wind. Here are 10 seastacks formation of the famous from all over the world, as quoted from Nature Expands so teacher.
1. Dun Briste, Ireland
Dun Briste, is a spectacular sea stack, estimated height of about 50 meters (165ft), located 80 meters (260ft) from Downpatrick Head, in the town-land of Knockaun, east of Ballycastle, Ireland. Downpatrick Head is the place where the Atlantic Ocean has gouged a large bay on the cliff tops mighty and they have been swept away by the relentless sea breeze to the exclusion of all vegetation except grass.
Every year, Downpatrick frequented by bird watchers, who come to observe and record the many species of birds that take a position at the level of the stack when the seasons change.
2. Sail Rock, Russia
Sail Rock, or Parus Rock is a natural sandstone monolith located on the Black Sea, in Krasnodar Krai, Russia. This stone resembles a very large ship screen and that is where its name comes .. Monolith is located 17 km (10.5mi) in the southeast of Gelendzhik, near the village Praskoveyevka (which is about 500 meters (1,650 feet) from the beach)
Sail rock has thin vertical slope facing the sea, isolated from the masses by force geological bedrock. More than three-quarters standing on the tide and lies perpendicular to the coast. The most remarkable of the landmarks (landmark) is proportion. While the thickness of only slightly more than one meter (3ft), but its height is about 25 meters (82ft) and a length of about 20 meters (66ft). Thus, the shape of the cliff is similar to sails.
3. Old Man of Hoy, Scotland, UK
Old Man of Hoy is a sea stack as high as 449 feet (137m) on the island of Hoy. It is a landmark (landmark) is typical of the Thurso to Stromness ferry, and was first climbed in 1966 Stack is a pile of red sandstone, perched on a basalt stone pedestal. He stood close to Rackwick Bay on the west coast of the island of Hoy, in the Orkney Islands, Scotland.
Stack is probably less than 400 years old and probably will not live longer, because there are indications that it will soon collapse. On maps drawn between 1600 and 1750, the area emerged as the cape without sea stack. William Daniell, a landscape painter, sketch this sea stack in 1817 as the column width with the top smaller and the arch at the base, from which its name is derived. Print a picture of it is still available in the local museum. Sometime in the early 19th century, a storm blew one of his legs and makes this form of sea stack as we see now, although erosion continues.
4. Risin og Kellingin, Faroe Islands
Risin og Kellingin (Risin and Kellingin) are two sea stacks just off the northern coast of the island Eysturoy Faroe Islands eidi close to town. The name Risin og Kellingin means Giant and the Witch, and relates to an old legend about their origins. Giant (Risin) is a sea stack as high as 71m (233ft) which is located far from the coast, and the witch (Kellingin) is a sea stack as high as 68m (223ft) which is located close to the beach, standing with legs apart.
Geologists estimate that Kellingin Faroese, which currently stands on two legs, will fall into the sea at approximately the next few decades during winter storms. There is already a part of the collapsed stack is interrupted at the beginning of the twentieth century.
5. Ko Tapu, Thailand
Ko Tapu is a limestone as high as about 20 meters (66 feet) in diameter increased from about 4 meters (13 feet) near the surface of the water to about 8 meters (26 ft) above. Ko tapu located approximately 40 meters (130 feet) west of the northern part of Khao Phing Kan (a pair of islands on the west coast of Thailand).
A scientific version of the formation of Ko Tapu says that the area is a reef barrier (barrier reef). Then, because of the movement of tectonic, reef breaks, and the parts were scattered in the area flooded by the rising sea. Wind, wave currents, and tides gradually erodes and the islands were formed, sometimes resulting in bizarre shapes, such as Ko Tapu. Related to tidal erosion seen at the bottom of the stone.
6. Ball's Pyramid, Australia
Ball Pyramid is located at 20 kilometers (12 miles) southeast of Lord Howe Island in the Pacific Ocean. Height 562 meters (1,844 feet), while the length measuring only 1,100 meters (3,600 feet) and a width of about 300 meters (980 feet), making it the tallest volcanic stack in the world. Pyramid Ball is part of the Lord Howe Island Marine Park.
In 2001, the type of insect that is commonly known as a tree or a lobster Lord Howe Island stick insect found attached in this stack, eighty years after the insect is believed to have become extinct. The full story can be read here.
7. Kicker Rock, Galapagos, Ecuador
Kicker Rock, also called Sleeping Lion is a rocky formation and a popular diving destination on the west side of Isla San Cristobal, the easternmost island in the Galapagos archipelago.
This gigantic rock towering 500 feet (152m) directly from the sea and the remains of a lava cone, now split into two. There is a warm current that passes through these two stones, which attracted the attention of hammerhead sharks and Galapagos sharks. Stone Kicker is also home to a large colony of sea birds.
8. Old Harry Rocks, UK
Old Harry Rocks are two chalk stack that is located on the coast of Dorset in southern England. The rocks mark the eastern end of the Jurassic Coast. The cliffs here is mainly composed of limestone, with a few ribbon flint in it.
Sea stack is continuously eroded by the sea and therefore is a feature that is always changing. In the 18th century, people still can walk from the mainland to Old Harry, which is a stack on the end closest to the sea.
9. The Twelve Apostles, Australia
Twelve Apostles rock formations are some form of pillars with various shapes are located on the coast of Port Campbell National Park, Great Ocean Road, Victoria. Different from its name, the stone pillars that there are not numbered twelve (there are only 9 pillars at the Twelve Apostles). Twelve Apostles also become a tourist attraction in Australia
During this time, the pillars of the Twelve Apostles are always hit by erosion, the strength of what once was the Twelve Apostles themselves. On July 4, 2005, one of the 50-meter-high pillar collapsed, so now only eight pillars. Another rock formations which suffered a similar fate is London Arch or formerly called London Bridge.
10. Tri Brata, Russia
At the entrance located Avacha Bay Tri Brata, three beautiful stack is considered as a symbol of Petropavlovsk-Kamchatsky, Kamchatka Krai main city, Russia.
Tri Brata is in Russian literally means "Three Brothers". Legend has it that the three brothers went to defend the city from the tsunami turned into a pillar of stone (at least not condemned their mothers).
