Calder's Geo
Calders Geo is an inlet in the western cliffs of Esha Ness in Northmavine on the Mainland, Shetland, Scotland. A cave on the north side of the geo has been measured at more than one and a half times the size of "The Frozen Deep", a chamber in Reservoir Hole under Cheddar Gorge in Somerset, potentially making it the largest natural chamber in Britain. Geologist Jonathan Swale used a laser range-finder to measure the interior of the cave, which is only accessible during calm seas. He claims that the structure is over tall and has a floor area of around .

Esha Ness
Esha Ness, also written Eshaness, is a peninsula on the west coast of Northmavine, on the island of Mainland, Shetland, Scotland. Esha Ness Lighthouse is located on the west coast of the peninsula, just south of Calder's Geo. The lighthouse was designed by David Alan Stevenson and commissioned in 1929. The hamlet of Tangwick contains the Tangwick Haa, a former Laird's house that has been a museum since 1987. Geology Esha Ness and the surrounding rocks are the remnants of a stratovolcano, which was active around 395 MYA. The rocks testify that eruptions were violent and explosive, with the ignimbrite of Grind o da Navir being a deposit from pyroclastic flows. The island of Muckle Ossa is what remains of the main vent of the Esha Ness volcano, while Kirn o Slettans is a side-vent. Geography Esha Ness is on the west coast of Northmavine on the island of Mainland, Shetland. It lies to the northwest of St Magnus Bay, to the north of Papa Stour. There are several small settlements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northmavine
Northmavine or Northmaven (from Old Norse , "north of the narrow isthmus") is a peninsula in Shetland forming the northernmost part of Mainland. The peninsula has historically formed a civil parish of the same name. The modern Northmavine community council area has the same extent. The area of the parish is given as 204.1 km2. Summary Northmavine includes the villages of Hillswick, Ollaberry, and North Roe. An isthmus, Mavis Grind, about a hundred yards across, forms the sole connection with the rest of Mainland. The coast is indented by numerous bays and consists largely of high, steep rocks. There are a number of high, fissured, cavernous cliffs on the west coast, faced by many skerries, islets, and offshore rocks. The interior has a very small amount of arable land; it consists mostly of rough, rising ground, including Ronas Hill, the highest point in all Shetland. Esha Ness Lighthouse is situated on the Northmavine peninsula. Tangwick Haa Museum preserves the his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainland, Shetland
The Mainland is the main island of Shetland, Scotland. The island contains Shetland's only burgh, Lerwick, and is the centre of Shetland's ferry and air connections. Geography It has an area of , making it the third-largest Scottish island and the fifth largest of the British Isles after Great Britain, Ireland Ireland (, ; ; Ulster Scots dialect, Ulster-Scots: ) is an island in the North Atlantic Ocean, in Northwestern Europe. Geopolitically, the island is divided between the Republic of Ireland (officially Names of the Irish state, named Irelan ..., Lewis and Harris and Skye. Mainland is the second most populous of the Scottish islands (surpassed only by Lewis and Harris), and had 18,765 residents in 2011 compared to 17,550 in 2001.

Geo (landscape)
A geo or gio ( , from Old Norse gjá) is an inlet, a gully or a narrow and deep cleft in the face of a cliff. Geos are common on the coastline of the Shetland and Orkney islands. They are created by the wave driven erosion Erosion is the action of surface processes (such as Surface runoff, water flow or wind) that removes soil, Rock (geology), rock, or dissolved material from one location on the Earth's crust#Crust, Earth's crust and then sediment transport, tran ... of cliffs along faults and bedding planes in the rock. Geos may have sea caves at their heads. Such sea caves may collapse, extending the geo, or leaving depressions inland from the geo. Geos can also be created from this process.

Reservoir Hole
Reservoir Hole is a cave in Cheddar Gorge in Somerset, southwest England. It contains what is believed to be the largest chamber yet found under the Mendip Hills. The cave was first dug out in 1951 by members of Wessex Cave Club, and further progress was made in 1965 when "Moonmilk Chamber" was reached with the use of blasting. "Grand Gallery" was discovered in 1969, "Topless Aven" in 1970 and "Golgotha Rift" in 1973. In September 2012, after four years' work clearing a long passage, a group of diggers broke into a new chamber which was found to be high and long. Prior to the discovery, the largest void under the Mendip Hills was thought to be "Main Chamber" in GB Cave, which is high. Before the find in 2012, the cave was already noted for a number of fine formations, and the newly discovered chamber, which has been named "The Frozen Deep", contains pure-white pillars tall, as well as many stalagmites and stalactites. The possibility of a connection between Reservoir Hol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cheddar Gorge
Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar, Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton, Cheddar Man, estimated to be 9,000 years old, was found in 1903. Older remains from the Upper Late Palaeolithic era (12,000–13,000 years ago) have been found. The caves, produced by the activity of an underground river, contain stalactites and stalagmites. The gorge is part of a Site of Special Scientific Interest called Cheddar Complex. Cheddar Gorge, including the caves and other attractions, has become a tourist destination. In a 2005 poll of ''Radio Times'' readers, following its appearance on the television programme ''Seven Natural Wonders'' (2005), Cheddar Gorge was named as the second greatest natural wonder in Britain, surpassed only by Dan yr Ogof caves. The gorge attracts about 500,000 visitors per year. Geology Cheddar Gorge is located on the southern edge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Esha Ness Lighthouse
Esha Ness Lighthouse is situated at Esha Ness, on the Northmavine peninsula in the north-west mainland of the Shetland Islands, Scotland. It sometimes rendered as Eshaness Lighthouse. The lighthouse is at the westernmost extremity of the peninsula, exposed to the Atlantic Ocean. The lighthouse has a tapering square tower high and was built between 1925 and 1929 by David Alan Stevenson and Charles Alexander Stevenson, two of the famous 'lighthouse' Stevensons, grandsons of Robert Stevenson. It was built from concrete because of the unsuitability of the local stone. It flashes white every 12 seconds and has a nominal range of . The light is housed in an octagonal lantern atop the square tower, which was built at the top of a high cliff. The lighthouse replaced a temporary structure constructed in 1915 on the Eshaness peninsula to warn of the Ve Skerries some offshore to the south-west. This temporary structure was removed after World War I World War I or the Fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Alan Stevenson
David Alan Stevenson (21 July 1854 in Edinburgh – 11 April 1938) was a lighthouse engineer who built 26 lighthouses in and around Scotland. Life He was born on 21 July 1854 the son of David Stevenson and his wife, Elizabeth Mackay. His early years were spent at their home at 8 Forth Street in the eastern section of the New Town in Edinburgh. The family later moved to 45 Melville Street.

Caves Of Scotland
Caves or caverns are natural voids under the Earth's surface. Caves often form by the weathering of rock and often extend deep underground. Exogene caves are smaller openings that extend a relatively short distance underground (such as rock shelters). Caves which extend further underground than the opening is wide are called endogene caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorganisms, pressure, and atmospheric influences. Isotopic dating techniques can be applied to cave sediments, to determine the time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Caves
A sea cave, is also known as a littoral cave, 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 (geology), relict sea caves on former coastlines. Some of the largest wave-cut caves in the world are found on the coast of Norway, but are now 100 feet or more above present sea level. These would still be classified as littoral caves. By contrast, in places like Thailand's Phang Nga Bay, solutionally formed caves in limestone have been flooded by the rising sea and are now subject to littoral erosion, representing a new phase of their enlargement. Some of the best-known sea caves are European. Fingal's Cave, on the island of Staffa in Scotland, is a spacious cave some 70 m long, formed in columnar jointing, columnar basalt. The Blue Grotto (Capri), Blue Grotto of Capri, although smaller, is famous for the apparent luminescent quality ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landforms Of Shetland
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...
