Where is the Blue Hole located?
Blue Hole (Castalia)
The Blue Hole captured the public’s interest because of its size, about in diameter, clarity, vibrant blue hue, and enigmatic "bottomless" appearance. Contrary to prevalent belief, the depth of the Blue Hole is not unknown, but has been sounded and found to be about deep. Water temperature is about throughout the year. Floods and droughts have no effect on temperature or water level. The Blue Hole is fed by a passing underground stream which discharges of water daily into Sandusky Bay to the north, feeding into Lake Erie. The water contains lime, soda, magnesia and iron, and because the Blue Hole is anoxic, it cannot naturally sustain fish. The surrounding terrain is developed on limestone bedrock and exhibits karst topography due to dissolution of the limestone by ground water, creating water-filled sinkholes. The Blue Hole was known to American Indians and was first recorded in history in 1761. Several similar blue holes are known to local residents. The Blue Hole that once was a tourist attraction is now off limits to the public. It is located on the grounds of Castalia Trout Club. It is to be distinguished from another hole similar in size and eerie bluish-green color. This latter hole is owned by the Castalia State Fish Hatchery operated by the Ohio Department of Natural Resources, Division of Wildlife and is open for public viewing.
Blue Hole (Red Sea)
However, the Sinai Peninsula was occupied by Israel during the Six-Day War of 1967 (with Israel occupying the territory until 1982). The first people to dive the hole with modern scuba diving equipment were Israeli divers led by Alex Shell, who noticed the underwater arch in 1968. By the time Israel handed the Sinai Peninsula back to Egypt in 1982, the Blue Hole had developed a reputation as a diving site amongst the international scuba diving community.
Blue Line (TRAX)
Beyond East 10600 South, the Blue Line heads north-northwest until it reaches Sandy Civic Center (the former southern terminus of the Blue Line, until August 18, 2013). This station is several blocks east of Sandy City Hall and the South Towne Center Mall. The Porter Rockwell Trail runs by the east side of this station and, as the trail heads north, it crosses over to the west of the Blue Line tracks at East 10000 South/East 9800 South and then runs north parallel to the Blue Line until it ends at East 8530 South. From Sandy Civic Center, the Blue Line heads north, crossing East 10000 South/East 9800 South (Sego Lily Drive) and, while running along the west side of South 170 East, passing the east side of both Jordan High School and the South Towne Exposition Center. Just after crossing East 9400 South the Blue Line reaches an infill station, Sandy Expo, which provides service to Rio Tinto Stadium in addition to the South Towne Exposition Center.

Blue hole
The deepest blue hole in the world at 300.89 meters (987 feet) deep is in the South China Sea and is named the Dragon Hole, or Longdong. The second deepest blue hole in the world with underwater entrance at is Dean's Blue Hole, located in a bay west of Clarence Town on Long Island, Bahamas. Other blue holes are about half that depth at around . The diameter of the top entrance ranges typically from (Dean's Blue Hole) to (Great Blue Hole in Belize).
Great Blue Hole
This site was made famous by Jacques Cousteau, who declared it one of the top five scuba diving sites in the world. In 1971 he brought his ship, the "Calypso", to the hole to chart its depths. Investigations by this expedition confirmed the hole's origin as typical karst limestone formations, formed before rises in sea level in at least four stages, leaving ledges at depths of , , and . Stalactites were retrieved from submerged caves, confirming their previous formation above sea level. Some of these stalactites were also off-vertical by 5˚ in a consistent orientation, indicating that there had also been some past geological shift and tilting of the underlying plateau, followed by a long period in the current plane. The tilt indicates that this was a movement of the land, rather than a rise in sea level alone.
Blue Eye, Albania
The Blue Eye () is a water spring and natural phenomenon occurring near Muzinë in Vlorë County, southern Albania. A popular tourist attraction, the clear blue water of the river bubbles forth from a depth of more than fifty-metres. Divers have descended to fifty metres, but it is still unclear what the actual depth of the karst hole is.

Blue Hole (Red Sea)
The number of diver deaths in the Blue Hole is not known, one source suggests 130 in the last fifteen years. The majority of those killed were experienced, including highly trained technical divers and diving instructors. There have also been snorkelling deaths at the surface unrelated to the depth of the hole.
Oxley Wild Rivers National Park
The Gara Gorge is located south-east of Armidale along the Castledoyle Road off the Waterfall Way just east of Armidale. The remains of Australia's first public hydro-electric scheme can be viewed here. Gara Gorge is picnic area with tables, drinking water, toilets and gas barbecues. Known for scenic bush strolls and the Blue Hole which is commonly used for swimming. The Threlfall Walk follows the route of the historic 1894 hydro-electric scheme, along old embankments and through ancient cuttings, to a lookout platform high above the river. Crombies Cave, the longest granite cave in Australia at , can be found in the next small creek, Powers Creek, an easy walk to the south of the Blue Hole. As the creek flows under the fence from the surrounding grazing country, within it begins its journey underground to come out down stream. The cave can be accessed from here and negotiated for at least half its length. It contains very beautiful granite sculptures, gnammas and potholes, some big caverns and a small sandy beach near the lower exit. A climb down a small waterfall and a curving squeeze can be difficult for some to negotiate. The exits downstream can be difficult to find from the outside.

Santa Rosa, New Mexico
Santa Rosa has many natural lakes, an anomaly in the dry desert climate surrounding it. These are sinkholes that form in the limestone bedrock of the area and fill with water, and thus the lakes are connected by a network of underground, water-filled tunnels. The most famous of these is Blue Hole, a popular spot for diving, where cool water forms a lake over deep.
Portsea Hole
The Portsea Hole in Port Phillip is about from the Portsea Pier. To the north there is a vertical wall approximately long. The wall has small overhangs which are home to plenty of marine life, including the beautiful Blue Devil fish. The Portsea Hole is a very popular boat dive site for recreational scuba diving activities.
Great Blue Hole
Initial measured depth of Great Blue Hole was which is the most often cited depth up to this day. An expedition by the Cambrian Foundation in 1997 measured the hole's depth as at its deepest point. This difference in measurement can be explained by ongoing sedimentation or by imprecision in measurements. The expedition's goal was to collect core samples from the Blue Hole's floor and document the cave system. To accomplish these tasks, all of the divers had to be certified in cave diving and mixed gases.

Belize Barrier Reef
In addition to its barrier reef, it also boasts three distinct Caribbean atolls: Turneffe Atoll, Glover's Reef and Lighthouse Reef. Lighthouse Reef is the most easterly diving area in Belize, it is home to the Great Blue Hole, made famous by Jacques Cousteau in 1970; Turneffe Atoll lies directly to the east of Belize City and is the nearest of the atolls to the capital. These different reefs provide diverse scuba diving opportunities that include walls, pinnacles and reef flats that are located throughout an enormous area of sea.
Blue Lake (Croatia)
Blue Lake ( or "Plavo jezero") is a karst lake located near Imotski in southern Croatia. Like the nearby Red Lake, it lies in a deep sinkhole possibly formed by the collapse of an enormous cave. The total depth from the upper rim is around 220 meters, while water depth varies with season. In spring, when the snow from surrounding mountains melts, it can reach 90 m, and in 1914 it reached 114 m, overflowing the southern rim. The lake is a popular destination for hiking and sight-seeing.
Blue Hole (Rawley Springs)
The swimming hole has not been developed with a parking area and easy access, although for some this is also the allure. Most people park on the shoulder of Route 33 just past Rawley Springs heading west. A short but steep climb down to the river follows. The path's location is unmarked but worn enough to be noticeable.
Stephanie Schwabe
Schwabe is the founder and director of the Rob Palmer Blues Holes Foundation, a nonprofit organization.

Blue Mountains (New South Wales)
The Blue Mountains are a mountainous region and a mountain range located in New South Wales, Australia. The region borders on Sydney's metropolitan area, its foothills starting about west of centre of the state capital. The public's understanding of the extent of the Blue Mountains is varied, as it forms only part of an extensive mountainous area associated with the Great Dividing Range. Officially the Blue Mountains region is bounded by the Nepean and Hawkesbury rivers in the east, the Coxs River and Lake Burragorang to the west and south, and the Wolgan and Colo rivers to the north. Geologically, it is situated in the central parts of the Sydney Basin.

Jackson Hole
Jackson Hole is a valley between the Teton Mountain Range and the Gros Ventre Range in Wyoming sitting near the border of Idaho. The term "hole" was used by early trappers or mountain men, who primarily entered the valley from the north and east and had to descend along relatively steep slopes, giving the sensation of entering a hole. These low-lying valleys surrounded by mountains and containing rivers and streams are good habitat for beaver and other fur-bearing animals.
Mount Hay (New South Wales)
Mount Hay, a mountain that is part of the Mt Hay Range of the Blue Mountains Range which is a spur off the Great Dividing Range, is located in the Blue Mountains National Park, New South Wales, Australia.

Mount Hay is approximately AMSL and is one of several basalt caps located within the UNESCO World Heritage Greater Blue Mountains Area.
Winmalee, New South Wales
Originally known as North Springwood, Winmalee was officially established in 1972. Springwood is historically significant as the first settlement in the Blue Mountains. Winmalee is surrounded by Blue Mountains National Park. This National Park is on the World Heritage List and is known as the Greater Blue Mountains Area World Heritage Site. The Blue Mountains area is unofficially known as "The City Within a World Heritage National Park". Winmalee extends north from Linksview Road and Birdwood Avenue to Coramandel Avenue and east to a point part-way along Singles Ridge Road.
Blue Mountains (New South Wales)
Following European settlement of the Sydney area, the area was named the "Carmarthen and Lansdowne Hills" by Arthur Phillip in 1788. The Carmarthen Hills were in the north of the region and the Lansdowne Hills were in the south. The name "Blue Mountains", however, was preferred and is derived from the blue tinge the range takes on when viewed from a distance. The tinge is believed to be caused by Mie scattering which occurs when incoming light with shorter wavelengths is preferentially scattered by particles within the atmosphere imparting a blue-greyish colour to any distant objects, including mountains and clouds. Volatile terpenoids emitted in large quantities by the abundant eucalyptus trees in the Blue Mountains may cause Mie scattering and thus the blue haze for which the mountains were named.

Most of the film is set in Cornwall and filmed there, many scenes are actually cut showing several different beaches and villages as if they were all adjoining, allowing the main parts of Cornwall to be incorporated into a single place.
The main location of the Aqua Shack is in Mousehole cut into St Ives, while other locations in Cornwall included a rock high above Chapel Porth for the mystical seaweed scene, Godrevy, Newquay and St Ives for some of the street scenes. The scene filmed at the train station was in St. Erth, just outside Hayle. The map examined by JC, Josh and Dean whilst trying to work out where Terry has gone on the bike shows Godrevey Point and the B3301 road, a few miles north of Hayle. The scene where JC and Chloe argue through the windscreen of the van have is at Trevellas Porth Valley, also known as Blue Hills, between St. Agnes and Perranporth. The location of the second Aqua Shack is Kynance Cove Cafe, at Kynance Cove on Lizard Point. The hotel where Josh and Dean take Terry for the cream tea is the Tregenna Castle Hotel, on the outskirts of St Ives, whilst the village hall scene was filmed at Rose Hill, just off Bunkers Hill in the Downalong area of St Ives.

George Stevens' 1814 Federal style house also still stands on Union Street.
Blue Hills (Washington)
The Blue Hills are perched on the north edge of the Seattle uplift, an east-west trending syncline or arch between the Seattle Fault and Tacoma fault formed by north-south compression of the bedrock. (See Puget Sound faults#Geological setting.)
Sharp downwarping of these formations has created numerous faults, including the dip-slip (vertical movement) Gold Creek fault that separates the two mountains. Strands of the Seattle fault, which east of here trend nearly due west-east, appear to turn to the southwest in the vicinity of Green Mountain.
Blue Line (CTA)
The O'Hare Branch is the longest section of the Blue Line () and comprises both the oldest and newest segments of the entire route. The line starts at O'Hare International Airport in an underground station below the main parking garage, servicing Terminals 1, 2, and 3. The line emerges in the median of the O'Hare main access road (Interstate 190) just northwest of Terminal 5, about a mile (1.6 km) west of Mannheim Road. The line runs in the median of Interstate 190 east through Rosemont. The line has a stop at River Road in Rosemont, which is also the location of one of the line's two storage yards, then tunnels beneath the Kennedy Expressway/Northwest Tollway interchange near the Des Plaines River. The line runs in the median of the Kennedy Expressway (Interstate 90) until a point southeast of Addison Street. South of Addison Street, the line exits the freeway and enters a subway under Kimball Avenue. The line travels under Kimball Avenue and Milwaukee Avenues through Logan Square. South of Logan Square, the line emerges above ground onto an elevated structure parallel to Milwaukee Avenue. This section of structure, built in 1895 as part of the Metropolitan Elevated's Northwest Branch, is the oldest portion of the Blue Line, and the sole section of the line on an elevated viaduct. The three stations on this section (California Avenue, Western Avenue, and Damen Avenue) are also the only three stations on the line to use side platforms instead of island platforms.

Blue Lake (New South Wales)
The Blue Lake is one of only four cirque lakes found in mainland Australia. The other three, Cootapatamba, Albina, and Club, are shallower and are held entirely by terminal moraines. Blue Lake's valley contains the best-developed glacial features in the Kosciuszko National Park alpine area of New South Wales. It was recognised as a wetland of international importance on 17 March 1996 when a area, comprising the lake and its surrounds, including nearby Hedley Tarn, was designated Ramsar Site 800 under the Ramsar Convention on wetlands. The lake lies within the Australian Alps National Parks and Reserves.
Great Blue Hill
Great Blue Hill (called Massachusett by Native Americans) is a hill of 635 feet (194 m) located within the Blue Hills Reservation in Milton and Canton, Massachusetts 10 miles (15 km) southwest of downtown Boston. It is the highest point in Norfolk County. The modern name for the hill was given by early European explorers who, while sailing along the coastline, noticed the bluish hue of the exposed granite faces when viewed from a distance (due to Riebeckite). The Blue Hills' eastern slopes face the ocean and lie within Quincy. The area attracted quarrying for its "blue granite".
The name of the Massachusett Indian tribe and their language (and thus the name of the Bay, Colony, Commonwealth/State, etc.) derive from the Massachusett name for the hill: "massa-adchu-es-et", where "massa-" is "large", "-adchu-" is "hill", "-es-" is a diminutive suffix meaning "small", and "-et" is a locative suffix, identifying a place.

Mel's Hole
Waters made guest appearances on Bell's show in 1997, 2000, and 2002. Rebroadcasts of those appearances have helped create what's been described as a "modern, rural myth". The exact location of the hole was unspecified, yet several people claimed to have seen it, such as Gerald R. Osborne, who used the ceremonial name Red Elk, who described himself as an "intertribal medicine man...half-breed Native American / white", and who told reporters in 2012 he visited the hole many times since 1961 and claimed the US government maintained a top secret base there where "alien activity" occurs. But in 2002, Osborne was unable to find the hole on an expedition of 30 people he was leading.

Octopus Hole
Octopus Hole is a designated conservation area on the Washington's Hood Canal. It is located immediately off of Highway 101, just over three miles North of Hoodsport. The site is marked with conservation signs, an old sign from Mike's Dive Shop (now closed), and two very small parking areas on both lanes of the highway. Similar to the close-by Sund Rock conservation area, Octopus Hole is very popular with Scuba divers who enjoy diving the walls associated with the site to view various underwater creatures, including but not limited to Lingcod, Giant Pacific Octopus, Wolf Eel, sea cucumber, and nudibranch. The walls on this site are accessible as shore dives. To access the dive sites on the Hood Canal from the highway, divers must straddle the Highway 101 guard rail, then walk down the crude steps to the shore, some 20–30 feet below. There is no fee to access this site, which is publicly accessible.
Castalian Spring
In Castalia, Ohio, named after the famed site, the Blue Hole limestone configurations were tourist attractions for many years and are now fish hatcheries. Waters in the blue holes are of a constant temperature and never freeze over despite northern Ohio's cold temperatures. The water which averages 30,000 gallons an hour was first used to supply a local mill.

Happy Valley, Hong Kong
On 19 December 1941, the Japanese Imperial Army entered the hill east of the valley and fought their way to Blue Pool Road. On (now Blue Pool Road) a number of large massacres occurred, most notably the Blue Pool Road Massacre, where civilians were bayoneted. Civilians and Soldiers captured were kept in the appalling conditions of 'the black hole of Hong Kong' (a house on Blue Pool Road). The Japanese later advanced up to Wong Nai Chung Gap, where the battle of Wong Nai Chung gap occurred, resulting in Japanese control of the gap. Although the low-areas of Happy Valley were captured, areas surrounding Leighton hill and Morrison Hill were still contested until later in the Battle of Hong Kong.
Robinson's Hole
Robinson's Hole is the strait in Massachusetts' Elizabeth Islands separating Naushon Island from Pasque Island. It is one of four straits allowing maritime passage between Buzzards Bay and the Vineyard Sound. The others are Canapitsit Channel, Quick's Hole and Woods Hole.
Robinson's Hole is located in the town of Gosnold.
The Snow Hole
The Snow Hole is located in the Taconic Mountains, New York, USA along the ridge line between Bald Mountain and the White Rock (Taconic Mountains). It is a crevasse in which snow can be found well into the summer. The Snow Hole can be accessed by hiking the Taconic Crest Trail about 2.75 miles north from the Petersburgh Pass parking area just off of Route 2. The Snow Hole is located at . Finding the location of the Snow Hole can be confusing, as several maps (including Google maps and USGS Berlin quadrangle, 1:25,000 scale - 1988) mark the location of the Snow Hole "summit" at . However, that is a separate mountain summit and not the actual Snow Hole. The posted hiking map at the kiosk to the Taconic Crest Trail at Petersburgh Pass has the location correctly identified. Typically the crevasse has snow at the bottom of it year round.
Blue hole
Most blue holes contain freshwater and saltwater. The halocline is the point in these blue holes where the freshwater meets the saltwater and where a corrosive reaction takes place that eats away at the rock. Over time this can create side passages, or horizontal "arms", that extend from the vertical cave. These side passages can be quite long; e.g., over in the case of the Sawmill Sink in the Bahamas.

Black Hole is a feature-length documentary film about the blockade opposing the expansion of Whitehaven Coal's Maules Creek coal mine in the Leard State Forest, New South Wales. It was directed and produced by Joao Dujon Pereira and premiered on 3 September 2015 at the Environmental Film Festival Australia in Melbourne. Interview subjects appearing in the film include Jonathan Moylan, an environmental activist responsible for the production and distribution of a fraudulent press release regarding the ANZ bank's financial relationship with the coal mine in 2013.
O'Hare station
O'Hare is the 'L' station at the northwestern terminus of the CTA's Blue Line. It is a subway station with two island platforms serving three tracks, located at O'Hare International Airport, 17 miles (27 km) northwest of the Chicago Loop. The station is located underneath the O'Hare parking garage. Trains are scheduled to depart from O'Hare roughly every 2–7 minutes during rush-hour periods and take about 40 minutes to travel to the Loop. It is the westernmost station of the 'L' system. It is also the only station without coordinates in Chicago's grid system, as O'Hare lines up with no street in the city. It is the only underground terminus, the only terminal where a premium fare applies, and is the only terminal that does not directly connect to any CTA or Pace buses. It is also one of two terminals (the other being Dempster-Skokie on the Yellow Line) that does not have a yard assigned to it (the yard is located at Rosemont, one stop east).
Blue hole
A blue hole is a large marine cavern or sinkhole, which is open to the surface and has developed in a bank or island composed of a carbonate bedrock (limestone or coral reef). Blue holes typically contain tidally influenced water of fresh, marine, or mixed chemistry. They extend below sea level for most of their depth and may provide access to submerged cave passages. Well-known examples can be found in South China Sea (Dragon Hole), Belize (Great Blue Hole), the Bahamas (Dean's Blue Hole), Guam, Australia (in the Great Barrier Reef), and Egypt (in the Red Sea).
Blue Hole (Red Sea)
The Blue Hole was historically avoided by Bedouin tribes people who inhabited the area. There was a local Bedouin legend that the Blue Hole is cursed by the ghost of a girl who drowned herself there to escape from an arranged marriage.
Blue John Canyon
The canyon is located southwest of the Horseshoe Canyon Unit of the National Park and 42 miles (67 km) south of Green River. It runs for approximately and is a tributary of Horseshoe Canyon, running northeastwards from the Robbers Roost Flats.
Blue Hole (New Mexico)
Since Santa Rosa, New Mexico is at an elevation of , it is necessary for divers to use high-altitude dive tables to compute the dive profile and decompression stops when diving in the Blue Hole.
Macarthur, New South Wales
Mushroom Tunnel is located just off the Remembrance Driveway (Old Hume Highway) heading towards Tahmoor and was built in 1867. It is considered one of the earliest pre-Federation railway tunnels in New South Wales. In 1919 the 65 metre long tunnel fell into disuse when a new railway deviation was built. The tunnel then served as a mushroom farm and ammunition storage facility during the war years. Currently the tunnel is empty although it is popular with ghost-hunters due to many local folk tales claiming that it is haunted. Subsequently it has been featured by both print and television media.Thirlmere Lakes National Park is part of the Blue Mountains Heritage Area in which the park consists of 5 important freshwaters lakes that are abundant in waterbirds and native reeds. The lakes are among the last undisturbed lakes within the proximity of Sydney and are believed to have high ecosystem-related and environmental scientific value. ("For more information, see Thirlmere Lakes National Park".)
Greenwood Tunnel
The Greenwood Tunnel is a historic railroad tunnel constructed in 1853 by Claudius Crozet during the construction of the Blue Ridge Railroad. The tunnel was the easternmost tunnel in a series of four tunnels used to cross the Blue Ridge Mountains of Virginia. Located near Greenwood in Albemarle County, Virginia, the tunnel was used by the Chesapeake and Ohio Railway (C&O) until its abandonment in 1944. The tunnel still exists, though sealed, next to the old C&O line, now owned by CSX Transportation and leased to the Buckingham Branch Railroad, which runs through a cut bypassing the old tunnel.
Paul Hosie
Hosie was born on 30 June 1967. He gained his Cave Diving qualification in 1997. Over the past ten years, Hosie has been involved in the discovery and mapping of over 10,000m of new cave passages in Australia. This has included the exploration of remote cave diving sites in Australia including Kija Blue Sinkhole in Australia's Kimberley region (ADM Issue 24/2006 ). Hosie has been recognised as a member of the World Exploration Team of Divers in Advanced Diver Magazine and was the recipient of the 2003 Oztek Diver of the Year Award.  In 2007, Hosie was awarded the National Speleological Society (USA) Cave Diving Section - Exploration Award along with his team members for the exploration of Kija Blue Sinkhole  Hosie has been active in the caving community in WA. He is currently exploring the area of Eneabba to find new caves and pay homage to Jeff Butt, who was the inspiration for the inaugural Australian Speleological Federation Award for Exploration that he was awarded in 2007 from the Australian Speleological Federation.
Sugar Hollow
Sugar Hollow is located in the Blue Ridge Mountains of western Albemarle County, Virginia, United States. It is defined by the north and south forks of Moorman's River which drain into a reservoir built in 1947, that supplies water for the City of Charlottesville, Virginia. The Appalachian Trail runs north and south along the upper reaches of this beautiful natural area.
Cyanea dolichopoda
This Hawaiian lobelioid was discovered in the Blue Hole, a valley on Kauai near the Wailua River. The Blue Hole is deep, nearly surrounded by steep cliffs up to 900 meters tall, and wet, a very high rainfall area filled with waterfalls. Only four plants were ever found, three juvenile specimens and one plant just reaching flowering stage. Because the plant was so obviously an unknown species and was apparently on the brink of extinction, it was given a name. It was not seen again after 1992.
Temescal Canyon High School (Lake Elsinore, California)
The "Blue Hole", a school-wide pep club, forms a large part of Temescal Canyon student culture. Formed in 2002 by members of the football team who wanted something to do during the offseason, the Club is now an official school club open to all students. Members purchased TC-Blue T-shirts with a "6" on the back (symbolizing the 6th man) and "Blue Hole" in large, bold lettering on the front. They appear at basketball games, home and away, and sit behind the opposing team's bench. From beginning to end, they stand and chant phrases, hoping to mentally defeat the opponents as well as motivate their fellow student-athletes. Their antics include repeatedly heckling individual players with chants of "air ball", the turn-over countdown, and other attacks on play or attitude. The antics even target the officials, as poor calls are followed by boos and members dress as blind referees and parade the sidelines after a questionable call. The Southwestern League prompted new regulations prohibiting the club from sitting behind the opposition bench and name calling. The Club's rowdiness has been credited to some of the success of the boys' basketball team. The Blue Hole has also moved onto the football field, where they sit in a specially-marked "blue hole section", a seating area in which the bleachers are painted blue. Standing throughout the entire game, the Blue Hole cheers and sings, capping it all off with an "It's All Over" chant at the end of a victory.
Blue Hills, Turks and Caicos Islands
Blue Hills are the highest point of Turks and Caicos Islands, a British Overseas Territory located in the Caribbean, with an elevation of 49 metres (161 ft).
Blue Hole (Red Sea)
The Blue Hole is dived almost every day by recreational divers. Local dive centres take divers who are qualified to dive to 30m (AOW level or CMAS**) to do the site known as El Bells or Bells to Blue Hole. The entry is from the shore further along from the Blue Hole at an entry called The Bells. At 26m at the bottom of the Bells is a mini arch that should not be confused with the arch in the Blue Hole itself. The dive is then a wall dive that finishes crossing the Blue Hole saddle at a depth of 7m. Recreational divers do not get to see the Blue Hole arch when doing the Bells to Blue Hole dive.
Blue Hill (New York)
Blue Hill is a mountain in Sullivan County, New York. It is located west-southwest of Claryville. Denman Mountain is located east-southeast of Blue Hill.
Trevellas
The area towards Trevellas Porth is known as "Blue Hills" due to bluish in-ground slate. Trevellas valley has been a site for tin mining for several centuries, and in 1810 the Blue Hills Sett incorporated many of the small mines. Though Blue Hills closed in 1897, tin production has continued in Trevellas to the present and the Blue Hills works can be visited between April and October each year.
Devils Hole
Devils Hole is a geothermal pool within a limestone cavern in the Amargosa Desert in the Amargosa Valley of Nevada, east over the Amargosa Range and Funeral Mountains from Death Valley. Its waters are a near constant salinity and temperature (). The cavern is over deep and the bottom has never been mapped.
Devils Hole branches into deep caverns at least deep from an opening at the surface that is approximately . According to geologists, the caves were formed over 500,000 years ago. The pool has frequently experienced activity due to far away earthquakes in Japan, Indonesia and Chile, which have been likened to extremely small scale tsunamis.
Blue Mountains (ecoregion)
This ecoregion extends from the Redmond area of Central Oregon, across a wide swath of the Columbia Plateau in Eastern Oregon, to Hells Canyon on the Snake River at the border of the three states. The ecoregion is named for the Blue Mountains and contains a complex of basins and mountain ranges that, at average 2100-2900m, are lower and more open than the neighboring Cascades and Northern Rocky Mountains but do include some steep landscape of which Hells Canyon at 1,660m is North America's deepest gorge. The mountains of the ecoregion include the Strawberry Range, Greenhorn, Elkhorn, Aldrich and Maury Mountains in the Blue Mountains, the gentler Ochoco Mountains to the west and the rugged Wallowa Mountains to the east. Rivers include the Grande Ronde, Powder Rivers and Malheur Rivers, all tributaries of the Snake and the John Day and Umatilla Rivers, tributaries of the Columbia.
The First Session
Hole
Great Blue Hole
In 2012 Discovery Channel ranked the Great Blue Hole as number one on its list of "The 10 Most Amazing Places on Earth". In 2018, They featured a two-hour special titled "Discovery Live: Into the Blue Hole" featuring Fabien Cousteau and Richard Branson.
Blue Anchor, Cornwall
Blue Anchor is a hamlet in mid Cornwall, England, United Kingdom. It is in the civil parish of St Enoder It is situated on the old course of the A30 road (now re-routed south of the settlement as a dual carriageway bypass) between the villages of Fraddon and Penhale.
Blue Hole (New Jersey)
After people became afraid of it, the Blue Hole was largely abandoned. A possibility is that farmers and families in the area warned children against going to the Blue Hole because the Jersey Devil lived there and it would hurt or steal them. Locals still go to the area and use it as a party spot. There are many other 'blue holes' in the immediate vicinity, as well as quicksand and other seasonal ponds and lakes that form from springs seeping from high water table levels. The Blue Hole is not to be confused with the numerous former quarries in the area, which appear much larger and have a vibrant sky blue color.
Blue Lake (Otago)
Blue Lake is a small lake adjacent to the town of Saint Bathans in Central Otago, New Zealand. The lake is man-made, the result of sluicing operations that began in 1873 when John Ewing (1844–1922) formed the St.Bathans Channel Company, to mine the Kildare Hill Gold Claim in St Bathans. His company constructed a tailings channel and introduced hydraulic elevating to work the claim. As this work progressed the Kildare Hill Claim became the site of the deepest hydraulic elevating operation in the world, that would turn a 120-metre hill into a 68-metre hole. Work stopped in 1902 when there was insufficient fall in the tailings channel to carry away the tailings. By 1905 John Ewing was bankrupt as a result of poor investments in other locations. The Kildare Hill Claim was then taken up by the Scandinavian Water Race Company in that year. This company restarted operations and worked the claim until 1932, when it was finally abandoned due to the fear of undermining the town of St Bathans. Natural drainage from the surrounding hills filled the hole with water and created the present day lake. The Blue Lake is a key feature of modern-day St. Bathans and is used for swimming, fishing, bodyboarding, and kayaking.
Blue Mountain (Pennsylvania)
Blue Mountain Ridge, Blue Mountain, or the Blue Mountains of Pennsylvania is part of the geophysical makeup of the Ridge-and-Valley Appalachians in the U.S. state of Pennsylvania. It is a ridge that forms the southern and eastern edge of the Appalachian mountain range spanning over from the Delaware Water Gap as it cuts across the eastern half of the state on a slight diagonal from New Jersey tending southerly until it turns southerly curving into Maryland, and beyond.
