La Tomatina ( The Tamato Fight), Valencia, Spain

La Tomatina is a festival that is held in the Valencian town of Buñol, a town located in the East of Spain 30 km / 19 miles from the Mediterranean, in which participants throw tomatoes and get involved in this tomato fight purely for entertainment purposes. Since 1945 it has been held on the last Wednesday of August, during the week of festivities of Buñol.

The festival is in honor of the town's patron saints, Luis Bertran and the Mare de Deu dels Desemparats (Mother of God of the Defenseless), a title of the Virgin Mary. The tomato fight (or La Tomatina) has been a strong tradition in Buñol since 1944 or 1945. No one is completely certain how this event originated, but there is one popular theory that disgruntled townspeople rioted and attacked city councilmen with tomatoes during a town celebration. Whatever did happen to begin the tradition, it was enjoyed so much that it was repeated the next year, and the year after that, and so on. Other theories include a food fight among friends, a juvenile class war between bare-footed Trotskyist macarras and upper class pijos from Madrid on summer vacation, a volley of tomatoes from bystanders at a carnival parade, a democratic protest against the city council and the ensuing aftermath of an accidental truck spillage. The holiday was banned in the Spanish State period under Francisco Franco for having no religious significance, but returned in the 1970s after his demise. In 1957, demand for the popular festival led to its becoming official, with certain rules and restrictions. These rules have gone through many modifications over the years.

Another important landmark in the history of this festival is the year 1975. From this year onward, "Los Clavarios de San Luis Bertrán" (San Luis Bertrán is the patron of the town of Buñol) organized the whole festival and brought in the tomatoes, which had previously been brought by the local people. Soon after this, in 1980, the town council took over responsibility for organizing the festival.

Since then, the number of participants has increased year after year. In 2002, in the month of August La Tomatina of Buñol was declared a Festivity of International Tourist Interest by the Secretary Department of Tourism due to its success. In 2013, town officials introduced an entry fee and limited the number of participants, citing concerns over safety.

 

At around 11am many trucks haul the bounty of tomatoes into the centre of the town, Plaza del Pueblo. The tomatoes come from Extremadura, where they are less expensive. Technically the festival does not begin until one brave soul has climbed to the top of a two-story high, greased-up wooden pole and reached the coveted ham at the top. In practice this process takes a long time and the festival starts despite no one reaching the meaty prize. The signal for the beginning of the fight is firing of water cannons, and the chaos begins. Once it begins, the battle is generally every man for himself.

After an one hour the fighting ends. At this point, no more tomatoes can be thrown. The cleaning process involves the use of fire trucks to spray down the streets, with water provided from a Roman aqueduct. The authorities seem more concerned with cleaning the town than cleaning the visitors, so some people find water at the Bunol River to wash themselves, although some kind residents will hose passers-by down. Once the tomato pulp is flushed, the ground is clean due to the acidity of the tomato. 

Since 2013, the capacity of La Tomatina is regulated by selling tickets for the event, a measure that "guarantees the sustainability of the party, better security and  fun for the attenders [sic]”. In 2015, it is estimated that almost 145000 kg of tomatoes were thrown. As with previous years, participants of many nationalities are expected.

The Rules of La Tomatina

•     Do not bring bottles or hard objects as they can cause accidents.
  
•     Do not rip other people's T-shirts
•     You must squash the tomatoes before throwing them as this reduces the impact
•     Ensure you keep a safe distance from the lorries
•     As soon as you hear the second shot, you must stop throwing tomatoes

The Eisriesenwelt (World of the Ice Giants), Werfen, Austria

The Eisriesenwelt (German for "World of the Ice Giants") is a natural limestone and ice cave located in Werfen, Austria, about 40 km south of Salzburg. The cave is inside the Hochkogel mountain in the Tennengebirge section of the Alps. It is the largest ice cave in the world, extending more than 42 km and visited by about 200,000 tourists every year.

The Tennengebirge mountains were formed during the late Tertiary period, during the Würm glaciation period of the Pleistocene. The mountain range, one of the massifs in the Austrian Alps, is the largest karst plateau in the Salzburger Alps, and the Eisriesenwelt is located at the rim of this plateau. Although the cave has a length of 42 km, only the first kilometer, the area that tourists are allowed to visit, is covered in ice. The rest of the cave is formed of limestone.

Eisriesenwelt was formed by the Salzach river, which eroded passageways into the mountain. The ice formations in the cave were formed by thawing snow which drained into the cave and froze during winter.

Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside. In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.

The first official discovery of Eisriesenwelt was by Anton Posselt, a natural scientist from Salzburg, in 1879, though he only explored the first two hundred meters of the cave. Before his discovery, the cave was known only to locals, who, believing that it was an entrance to Hell, refused to explore it. In 1880, Posselt published his findings in a mountaineering magazine, but the report was quickly forgotten.

Alexander von Mörk (de), a speleologist from Salzburg, was one of the few people who remembered Posselt's discovery. He led several expeditions into the caves beginning in 1912, which were soon followed by other explorers. Von Mörk was killed in World War I in 1914, and an urn containing his ashes is inside a niche in the cave. In 1920, a cabin for the explorers, Forscherhütte, was built and the first routes up the mountain were established. Tourists began to arrive soon after, attracted by the cave's sudden popularity. Later another cabin, the Dr. Oedl House, and paths from Werfen and Tänneck were constructed.

In 1955 a cable car was built, shortening the 90-minute climb to 3 minutes. Today the Eisriesenwelt cave is owned by the National Austrian Forest Commission (de), which has leased it to the Salzburg Association of Cave Exploration since 1928. The Forest Commission still receives a percentage of the entrance fees.

The cave is open from May 1 to October 26 every year. Its operating hours are 9:00 a.m. to 4:30 p.m. in July and August and 9:00 a.m. to 3:30 p.m. in May/June and September/October. Temperatures inside the cave are usually below freezing, and warm clothing is recommended. Photography is not permitted once visitors are inside the cave.

The tour begins at the entrance to the cave, and continues inwards to Posselt Hall, a large room with a stalagmite called Posselt Tower in the centre. Past the Posselt Tower, one encounters an ashen cross on the wall of the cave, marking the farthest point of exploration of Anton Posselt. From there one can see the Great Ice Embankment, a massive formation that rises to a height of 25 metres and represents the area of greatest ice growth. Next is Hymir's Castle, named after a giant in Norse mythology. Here stalactites create a formation called Frigga's Veil, or the Ice Organ.

Next on the tour is the Alexander von Mörk Cathedral, one of the largest rooms in the cave and the final resting place of von Mörk's ashes. The final stop on the tour is the Ice Palace, a kilometre into the cave and 400 metres underground. From here, visitors must turn around and walk back through the caves to reach the entrance. The round-trip tour through the cave takes around one hour and 15 minutes.

The Richat Structure (Eye of the Sahara), Sahara Near Ouadane, West–Central Mauritania

The Richat Structure, also known as the Eye of the Sahara and Guelb er Richat, is a prominent circular feature in the Sahara near Ouadane, west–central Mauritania.

The Richat Structure is a deeply eroded, slightly elliptical dome with a diameter of 40 kilometers (25 mi). The sedimentary rock exposed in this dome ranges in age from Late Proterozoic within the center of the dome to Ordovician sandstone around its edges. The sedimentary rocks comprising this structure dip outward at 10°–20°. Differential erosion of resistant layers of quartzite has created high-relief circular cuestas. Its center consists of a siliceous breccia covering an area that is at least 30 kilometers (19 mi) in diameter.

Exposed within the interior of the Richat Structure are a variety of intrusive and extrusive igneous rocks. They include rhyolitic volcanic rocks, gabbros, carbonatites and kimberlites. The rhyolitic rocks consist of lava flows and hydrothermally altered tuffaceous rocks that are part of two distinct eruptive centers, which are interpreted to be the eroded remains of two maars. According to field mapping and aeromagnetic data, the gabbroic rocks form two concentric ring dikes. The inner ring dike is about 20 m in width and lies about 3 km from the center of Richat Structure. The outer ring dike is about 50 m in width and lies about 7 to 8 km from the center of this structure. Thirty-two carbonatite dikes and sills have been mapped within the Richat Structure. The dikes are generally about 300 m long and typically 1 to 4 m wide. They consist of massive carbonatites that are mostly devoid of vesicles. The carbonatite rocks have been dated as having cooled between 94 and 104 million years ago. A kimberlitic plug and several sills have been found within the northern part of the Richat Structure. The kimberlite plug has been dated to around 99 million years old. These intrusive igneous rocks are interpreted as indicating the presence of a large alkaline igneous intrusion that currently underlies the Richat Structure and created it by uplifting the overlying rock.

Spectacular hydrothermal features are a part of the Richat Structure. They include the extensive hydrothermal alteration of rhyolites and gabbros and a central megabreccia created by hydrothermal dissolution and collapse. The siliceous megabreccia is at least 40 m thick in its center to only a few meters thick along its edges. The breccia consists of fragments of white to dark gray cherty material, quartz-rich sandstone, diagenetic cherty nodules, and stromatolitic limestone and is intensively silicified. The hydrothermal alteration, which created this breccia, has been dated to have occurred about 98.2 ± 2.6 million years ago using the 40Ar/39Ar method.

Initially interpreted as an asteroid impact structure because of its high degree of circularity, the Richat Structure is now regarded by geologists as a highly symmetrical and deeply eroded geologic dome. After extensive field and laboratory studies, no credible evidence has been found for shock metamorphism or any type of deformation indicative of a hypervelocity extraterrestrial impact. While coesite, an indicator of shock metamorphism, had initially been reported as being present in rock samples collected from the Richat Structure, further analysis of rock samples concluded that barite had been misidentified as coesite. In addition, the Richat Structure lacks the annular depression that characterizes large extraterrestrial impact structures of this size. Also, it is quite different from large extraterrestrial impact structures in that the sedimentary strata comprising this structure is remarkably intact and "orderly" and lacking in overturned, steeply dipping strata or disoriented blocks. A more recent multianalytical study on the Richat megabreccias concluded that carbonates within the silica-rich megabreccias were created by low-temperature hydrothermal waters, and that the structure requires special protection and further investigation of its origin.

Princess Juliana International Airport, Simpson Bay, Sint Maarten

Princess Juliana International Airport (also known as Saint Maarten International Airport) is the main airport on the Caribbean island of Saint Martin, located on the Dutch side of the island in the country of Sint Maarten. In 2010, the airport handled 1,645,105 passengers and 60,870 aircraft movements. The airport serves as a hub for Windward Islands Airways and is the major gateway for the smaller Leeward Islands, including Anguilla, Saba, St. Barthélemy and St. Eustatius. It is named after Juliana of the Netherlands, who as crown princess landed here in 1944, the year after the airport opened. There is also an airport on the French side of the island, called Aéroport de Grand Case or L'Espérance Airport.

The airport is perhaps best known for very low-altitude flyover landing approaches due to one end of its runway being extremely close to the shore and Maho Beach.

 

 

The airport was started as a military airstrip in 1942. It was converted to a civilian airport in 1943. In 1964 the airport was remodeled and relocated, with a new terminal building and control tower. The facilities were upgraded in 1985 and 2001. Because of increased passenger traffic and the expected growth of passenger traffic in the near future, Princess Juliana International Airport is being heavily modernized following a three-phased masterplan, commissioned in 1997.

Phase I was a short-term program in order to upgrade existing facilities and improve the level of service at various points. This included widening, strengthening and renovating the runway, increasing the bearing capacity of the taxiways, construction of a new apron and an upgrade of the (old) terminal. Phase I was completed in 2001.

Phase II included the construction of a radar facility and a new air traffic control tower, the construction of a new and more modern, 27,000 square metres (290,000 sq ft), terminal, capable of handling 2.5 million passengers per year, and the construction of a Runway End Safety Area (RESA) of 150 metres (490 ft), including a 60 metres (200 ft) overrun, on both ends of its runway, to comply with ICAO rules. The new air traffic control tower and the radar station commenced operations on 29 March 2004, while the new terminal opened in late October 2006. The terminal has 4 jetways for large aircraft like 747s.

If traffic develops as forecast, Phase III of the masterplan will be executed, consisting of an extension of the new terminal building and the construction of a full parallel taxiway system. The new terminal building will also have more jetways and services etc.

However, the oil price increases since 2003 began impacting discretionary air travel worldwide by early 2008, and the prospect of further price increases threatens to reverse the recent expansion of tourist travel by jet which began with the 1980s oil glut.

In 1994, the Kingdom of the Netherlands and France signed the Franco-Dutch treaty on Saint Martin border controls, which allows for joint Franco-Dutch border controls on so-called "risk flights". After some delay, the treaty was ratified in November 2006 in the Netherlands, and subsequently entered into force on 1 August 2007.

In July 2016, KLM announced to serve the airport with direct flights from Amsterdam instead by a triangle route via Curaçao from October 2016. Due to this change, the airport lost its last regular Boeing 747 service - which was a famous photo opportunity on the nearby beach - as KLM uses Airbus A330s for the changed schedule.

Because the approach to Runway 10 is over water, pilots can become disoriented regarding their perceived altitude when operating under visual flight rules. Normal instrument checks, coupled with experience and situational awareness, mitigate potential problems. The departure from Runway 10 presents more "difficulties" than the approach, with a turn required to avoid mountains in the departure path.

Arriving aircraft approach the island on the last section of the final approach for Runway 10, following a 3° glide slope flying low over the famous Maho Beach. Pictures of low flying aircraft were published in several news magazines worldwide in early 2000. The thrilling approaches and ease of access for shooting spectacular images, made the airport one of the world's favorite places among planespotters. To meet changing international and local regulations a 150-metre (490 ft) safety extension was required.

Despite the reputed difficulties in approach, there have been no records of major incidents at the airport, although ALM Flight 980 crashed 30 miles (48 km) from St. Croix on 2 May 1970, after several unsuccessful landing attempts at TNCM in bad weather. Runway 10/28 was renumbered from 09/27 in late 2008. The runway is 45m wide.
