Geocache Description:

🌍 Galley Haed Cliffs 🌍

In geography and geology, a cliff is a vertical, or nearly vertical, rock exposure. Cliffs are formed as erosion landforms by the processes of weathering and erosion. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually formed by rock that is resistant to weathering and erosion. Sedimentary rocks most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff, formed by the movement of a geologic fault or landslide, or by differential erosion of rock layers of differing hardness. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also feature tributary waterfalls or rock shelters. Sometimes a cliff peters out at the end of a ridge, with tea tables or other types of rock columns remaining. Coastal erosion may lead to the formation of sea cliffs along a receding coastline. The Ordnance Survey distinguishes between cliffs (continuous line along the top edge with projections down the face) and outcrops (continuous lines along lower edge).


They can form near the ocean (sea cliffs), high in mountains, or as the walls of canyons and valleys. Waterfalls tumble over cliffs. Cliffs are usually formed because of processes called erosion and weathering. Weathering happens when natural events, like wind or rain, break up pieces of rock.


sea cliff. [′sē ‚klif] (geology) An erosional landform, produced by wave action, which is either at the seaward edge of the coast or at the landward side of a wave-cut platform and which denotes the inner limit of the beach erosion.

At a flat coast or flat shoreline, the land descends gradually into the sea. Flat coasts can be formed either as a result of the sea advancing into gently-sloping terrain or through the abrasion of loose rock. They may be basically divided into two parallel strips: the shoreface and the beach.


The spectacular sea cliffs attracted famous artists including Gustave Courbet and Claude Monet. Kalaupapa Cliffs, Hawaii – Located on the shore of the Pacific Ocean in the Molokai island of Hawaii, the Kalaupapa Cliffs are the highest sea cliffs in the world with a height of 1,010 meters (3,315 ft).


A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. ... Eventually, erosion will cause the stack to collapse, leaving a stump.


Cliffs are usually formed by rock that is resistant to weathering and erosion. Sedimentary rocks most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.


At headland, wave erosion is most concentrate because of wave refraction. Destructive waves erode along the line of weakness, e.g. fault line or joint, that lies across the headland. ... Further erosion enlarge the sea caves and finally joint together. A sea arch is formed. Located on the Hawaiian island of Molokai, Kalaupapa is a village at the base of the highest sea cliffs in the world, as recorded by the Guinness Book of World Records, dropping about 1,010 meters (3,315 feet) into the Pacific Ocean.


A sea cave, also known as a littoral cave, is a type of cave formed primarily by the wave action of the sea. The primary process involved is erosion. Sea caves are found throughout the world, actively forming along present coastlines and as relict sea caves on former coastlines.


Sea arches are a spectacular phenomena created by Mother Nature with a little help from oceans. They are usually composed of a soft rock that eroded over millions of years as waves hit land, carving caves and tunnels in the rock.


Kalaupapa Cliffs, Hawaii, USA. Towering some 2,000 feet above the Pacific Ocean, the Kalaupapa Cliffs on Hawaii's laid-back Molokai island are among the highest sea cliffs in the world.




To log this EarthCache please send me the answers for the logging tasks via my profile:


  1. Regarding to the above provided information, which kind of stone can you find here?
  2. In some cases the cliffs have one or more sea caves. Can you see one?
  3. In case you see a sea cave, where is it connected to?


Photos of the area are welcome but not a requirement (without giving away any of the answers)


Feel free to log your find straight away once you have sent the answers. If there is any issue, I will contact you.


Enjoy your visit!
