Ischigualasto, Argentina

Ischigualasto is a geological formation and a natural park associated with it in the province of San Juan, north-western Argentina, near the border with Chile. The Ischigualasto Provincial Park is located in the north-east of the province, and its northern border is the Talampaya National Park, in La Rioja, both of which belong to the same geological formation.



It has an area of 603.7 km2 (233 sq mi), most of them within the Valle Fértil Department, with a minor part in the Jachal Department of San Juan, at an altitude of about 1,300 m (4,265 ft) above mean sea level. The park is part of the western border of the Pampean Hills, and it features typical desert vegetation (bushes, cacti and some trees) which covers between 10 and 20% of the area. The climate is very dry, with rainfall mostly during the summer, and temperature extremes (minimum -10 °C, maximum 45 °C). There is a constant southern wind with a speed of 20-40 km/h after noon and until the evening, sometimes accompanied by an extremely strong zonda wind.


The Ischigualasto Formation contains Late Triassic (Carnian) deposits (231.4 -225.9 million years before the present), with some of the oldest known dinosaur remains, which are the world's first with regards to quality, number and importance. It is the only place in the world where nearly all of the Triassic is represented in an undisturbed sequence of rock deposits. This allows for the study of the transition between dinosaurs and ancient mammals; research is ongoing.



The arid badlands around the formation are known as Valle de la Luna ("Valley of the Moon") due to their rugged, otherworldly appearance. In the Carnian this area was a volcanically active floodplain dominated by rivers and had a strongly seasonal rainfall. Petrified tree trunks of Protojuniperoxylon ischigualastianus more than 40 m (131 ft) tall attest to a rich vegetation at that time. Fossil ferns and horsetails have also been found. Rhynchosaurs and cynodonts are by far the predominant findings among the tetrapod fossils in the park. Dinosaurs comprise only 6% of the findings, but these include early samples of the two major lineages of dinosaurs (ornithischians and saurischians). The carnivorous archosaur Herrerasaurus is the most numerous of these dinosaur fossils. Another important putative dinosaur with primitive characteristics is Eoraptor lunensis, found in Ischigualasto in the early 1990s.

Spotted Lake, Canada

Spotted Lake is a saline endorheic alkali lake located northwest of Osoyoos in Canada. It is located near the city of Osoyoos, beside Highway 3.



Spotted Lake is very highly concentrated with numerous different minerals. It contains some of the highest quantities (in the world) of magnesium sulfate, calcium and sodium sulphates. It also contains extremely high concentrations of 8 other minerals as well as some small doses of four others such as silver and titanium. Most of the water in the lake evaporates over the summer, leaving behind all the minerals. Large “spots” on the lake appear and depending on the mineral composition at the time, the spots will be different colors. The spots are made mainly of magnesium sulfate, which crystallizes in the summer. In the summer only the minerals in the lake remain, and they harden to form natural “walkways” around and between the spots.



Originally known to the First Nations of the Okanagan Valley as Khiluk, they considered it a sacred site, primarily as they regarded the lake's waters as possessing therapeutic value. The lake’s minerals were also put to use in the manufacture of ammunition for World War I. The lake and its surrounding land were not actually owned by the First Nations - it was owned by the Ernest Smith Family for about 40 years. Despite this, the First Nations were very protective of the lake; so protective that when, in 1979, Smith attempted to have a spa at the lake, they attempted to buy the lake so they could keep it as a sacred site. After over 20 years of trying but failing to convince Smith to sell the land, they finally did make a deal in late October 2001, when they bought 22 hectares of land for a total of $720,000. The First Nations paid $150,000 while the Indian Affairs Department paid the remainder.

Kola, Russia

The Kola Superdeep Borehole is the result of a scientific drilling project of the Soviet Union on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970 using the Uralmash-4E, and later the Uralmash-15000 series drilling rig. A number of boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft) in 1989, and is the deepest hole ever drilled, and the deepest artificial point on earth. For two decades it was also the world's longest borehole, in terms of measured depth along the well bore, until surpassed in 2008 by 12,289 m (40,318 ft) long Al Shaheen oil well in Qatar, and in 2011 by 12,345 metres (40,502 ft) long Sakhalin-I Odoptu OP-11 Well (offshore the Russian island Sakhalin).



The initial target depth was set at 15,000 m (49,000 ft). On 6 June 1979, the world depth record held by the Bertha Rogers hole in Washita County, Oklahoma, at 9,583 m (31,440 ft) was broken. In 1983, the drill passed 12,000 m (39,000 ft), and drilling was stopped for about a year to celebrate the event. This idle period may have contributed to a break-down on 27 September 1984: after drilling to 12,066 m (39,587 ft), a 5,000 m (16,000 ft) section of the drill string twisted off and was left in the hole. Drilling was later restarted from 7,000 m (23,000 ft). The hole reached 12,262 m (40,230 ft) in 1989. In that year the hole depth was expected to reach 13,500 m (44,300 ft) by the end of 1990 and 15,000 m (49,000 ft) by 1993. However, due to higher than expected temperatures at this depth and location, 180 °C (356 °F) instead of expected 100 °C (212 °F), drilling deeper was deemed unfeasible and the drilling was stopped in 1992. With the expected further increase in temperature with increasing depth, drilling to 15,000 m (49,000 ft) would have meant working at a projected 300 °C (570 °F), at which the drill bit would no longer work.



The site is controlled by the State Scientific Enterprise on Superdeep Drilling and Complex Investigations in the Earth's Interior (GNPP Nedra) as the Deep Geolaboratory. As of 2003, the deepest active bore, SG-5, is 8,578 m (28,143 ft) and with a 214 mm (8.4 in) diameter. The project was closed down in late 2005 due to lack of funding. All the drilling and research equipment was scrapped and the site has been abandoned since 2008.

Don Juan Pond, Antarctica

Don Juan Pond, also called Lake Don Juan, is a small and very shallow hypersaline lake in the west end of Wright Valley (South Fork), Victoria Land, Antarctica, 9 kilometres (5.6 mi) west from Lake Vanda. It is wedged between the Asgard Range in the south and the Dais in the north. On the west end there is a small tributary and a feature that has been described as a rock glacier. Don Juan Pond is the saltiest body of water on earth with a salinity level of over 40%.



Don Juan Pond was discovered in 1961. It was named for two helicopter pilots, Lt Don Roe and Lt John Hickey, who piloted the helicopter involved with the first field party investigating the pond. On that initial investigation, the temperature was −30 °C (−22 °F) and the water remained in a liquid state.


Don Juan Pond is a shallow, flat-bottom, hyper-saline pond. It has greater salinity than the Dead Sea or even Lake Assal (Djibouti) (the same is true for Lake Vanda and perhaps other lakes in the McMurdo Dry Valleys). It has been claimed that the salinity in Don Juan Pond is over 18 times the ocean's salinity, compared to that of the Dead Sea at about 8 times that of the ocean. The fact that it is the only one of the Antarctic hypersaline lakes that almost never freezes is an indication of its top rank in salinity among the world's lakes.



The salinity is high enough that it doesn't freeze in winter. Therefore, unlike other lakes and ponds in the dry valleys, it has no ice cover. It has been described as a groundwater discharge zone. The dominant ions in solution are calcium and chloride. The area around Don Juan Pond is covered with sodium chloride and calcium chloride salts that have been precipitated as the water evaporated. Area and volume of Don Juan Pond varies over time. According to the USGS topo map published in 1977, the area was approximately 0.25 km2 (62 acres), However, in recent years the size of the pond has shrunk considerably. The maximum depth in 1993–94 was described as "a foot deep" (30 cm). In January 1997, it was approximately 10 centimetres (3.9 in) deep; in December 1998 the pond was almost dry everywhere except for an area of a few tens of square meters. Most of the remaining water was in depressions around large boulders in the pond. The calculated composition for its water is CaCl2 3.72 mol/kg and NaCl 0.50 mol/kg, at the temperature of -51.8°C. That would be equivalent to 413 g of CaCl2 and 29 g of NaCl per kg of water.

Fort Knox, United States

The United States Bullion Depository, often known as Fort Knox, is a fortified vault building located adjacent to Fort Knox, Kentucky, used to store a large portion of United States official gold reserves and occasionally other precious items belonging or entrusted to the federal government.



The United States Bullion Depository holds 4,577 metric tons (5046 tons) of gold bullion (147.2 million oz. troy). This is roughly 2.5% of all the gold ever refined throughout human history. Even so, the depository is second in the United States to the Federal Reserve Bank of New York's underground vault in Manhattan, which holds 7,000 metric tons (7716 tons) of gold bullion (225.1 million oz. troy), some of it in trust for foreign nations, central banks and official international organizations.


The fortress-like structure lies the gold vault lined with granite walls and protected by a blast-proof door weighing 22 tons. No single person is entrusted with the entire combination to the vault. Several members of the Depository staff must dial separate combinations known only to them. Beyond the main vault door, smaller compartments provide further protection. The facility is ringed with fences and is guarded by the United States Mint Police. The Depository premises are within the site of Fort Knox, a United States Army post, allowing the Army to provide additional protection. The Depository is protected by layers of physical security, alarms, video cameras, armed guards, and the Army units based at Fort Knox, including Apache helicopter gunships of 8/229 Aviation based at Godman Army Airfield, the 16th Cavalry Regiment, the 19th Engineer Battalion, formerly training battalions of the United States Army Armor School, and the 3rd Brigade Combat Team of the 1st Infantry Division, totaling 30,000 soldiers, with associated tanks, armored personnel carriers, attack helicopters, and artillery.



There is an escape tunnel from the lower level of the vault to be used by someone accidentally locked in. Since the opening of the depository, the Federal government has disclosed very little information about the security systems and technologies used. What is generally known about the security systems at the Gold Depository mostly dates from the late 1930s. For example, the small turret-like structures at the corners of the building are firing positions for guards with Thompson submachine guns, the standard longarm of the Mint Police when the Depository was built. It is rumored that everything from minefields, to ground-sweeping radars, to body capacitance wires, to automated machine guns triggered by interrupting laser beams are emplaced to guard the building and its approaches. It is rumored that, like the French national bank in Paris, the vaults can be filled with water. The Federal government will neither confirm nor deny the rumors. Employees are sworn to secrecy and cannot divulge information about the vault's security.


For security reasons, no visitors are allowed inside the depository grounds. This policy has been enforced ever since the vault opened and the only exception was an inspection by members of the United States Congress and the news media on September 23, 1974 led by then Director of the United States Mint Mary Brooks.

Boutique of Bijan, United Stetes

Born in Tehran, Iran, Bijan migrated to Los Angeles in 1973. His exclusive boutique on Rodeo Drive in Beverly Hills was established in 1976. It has been described as "the most expensive store in the world".



Bijan's main residence was in Beverly Hills, California, but he was also known to own residences in New York and Malibu, as well as Milan and Florence, Italy. Up until the time of his death, Bijan was one of few Iranians in the media limelight who were still permitted to enter Iran. Bijan was also known for his automobiles. Most notable in his car collection was a yellow Bentley Azure with black interior, as well as a Black Bentley Azure with yellow interior. He was also known to have a black Mercedes-Benz SLR McLaren with a customized paint scheme, a yellow Ferrari 430 Spider, a yellow Rolls Royce Drophead coupe, and a Bugatti Veyron, all of which he was known to park outside of his Rodeo Drive boutique.


In the late 1980s Bijan designed a golden Colt revolver. The gun had a leather handgrip fashioned for a .38-cal. Colt revolver inlaid in the cylinder was 56 grams of 24-karat gold, the gun was placed in a mink pouch in a Baccarat crystal case embossed with the customer's name. Bijan's own signature is engraved in gold on the barrel of the gun. Only 200 such guns were made. In 2005, one of these guns sold to Jacob Nahamia at Christie's auction house for over $50,000 USD. In 2000 Bijan courted controversy when an advertisement featuring a "rotund model named Bella" and himself was at first rejected by New York magazines before it was accepted by Tina Brown's Talk magazine.



Bijan dressed some of the world's most powerful men: President of the United States Barack Obama, former President of the United States George W. Bush, former Governor of California Arnold Schwarzenegger, American actor Tom Cruise, German TV host Thomas Gottschalk, British actor Sir Anthony Hopkins, President of Russia Vladimir Putin, U.S. Senator John Kerry, former Prime Minister of the United Kingdom Tony Blair, Michael Jordan, Paul Allen, Jay Leno, Giorgio Armani, Usher, the richest person alive Carlos Slim Helu, owner of several casinosSteve Wynn, designer Oscar de la Renta, Thomas Bodin, Tom Ford, Shahram Nazeri, Former Beverly Hills Mayor Jimmy Delshad, Footballer Saba Shakeri, U.S. President Ronald Reagan and Lerad Dumani have all been dressed by Bijan.


Bijan's fragrances for both men and women are known for their distinctive circular glass flacon with an open center and a dividing web. When half full, the fragrance fills two separate chambers, seemingly defying the law of gravity that liquid seeks its own level. One of these perfume bottles is featured in the permanent exhibit of the Smithsonian Institution. According to the 2001 Los Angeles Times Calendar Section, the Bijan Perfume and Fashion Business has brought in an estimated $4.2 billion in sales worldwide.

Oldest Tree in the World, Sweden

The world's oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.



For many years the spruce tree has been regarded as a relative newcomer in the Swedish mountain region. "Our results have shown the complete opposite, that the spruce is one of the oldest known trees in the mountain range," says Leif Kullman, Professor of Physical Geography at Umeå University. A fascinating discovery was made under the crown of a spruce in Fulu Mountain in Dalarna. Scientists found four "generations" of spruce remains in the form of cones and wood produced from the highest grounds.


The discovery showed trees of 375, 5,660, 9,000 and 9,550 years old and everything displayed clear signs that they have the same genetic makeup as the trees above them. Since spruce trees can multiply with root penetrating braches, they can produce exact copies, or clones. The tree now growing above the finding place and the wood pieces dating 9,550 years have the same genetic material. The actual has been tested by carbon-14 dating at a laboratory in Miami, Florida, USA. Previously, pine trees in North America have been cited as the oldest at 4,000 to 5,000 years old. In the Swedish mountains, from Lapland in the North to Dalarna in the South, scientists have found a cluster of around 20 spruces that are over 8,000 years old.



Although summers have been colder over the past 10,000 years, these trees have survived harsh weather conditions due to their ability to push out another trunk as the other one died. "The average increase in temperature during the summers over the past hundred years has risen one degree in the mountain areas," explains Leif Kullman. Therefore, we can now see that these spruces have begun to straighten themselves out. There is also evidence that spruces are the species that can best give us insight about climate change. The ability of spruces to survive harsh conditions also presents other questions for researchers.


Have the spruces actually migrated here during the Ice Age as seeds from the east 1,000 kilometres over the inland ice that that then covered Scandinavia? Do they really originate from the east, as taught in schools? "My research indicates that spruces have spent winters in places west or southwest of Norway where the climate was not as harsh in order to later quickly spread northerly along the ice-free coastal strip," says Leif Kullman. "In some way they have also successfully found their way to the Swedish mountains."


The study has been carried out in cooperation with the County Administrative Boards in Jämtland and Dalarna.

Three Gorges Dam, China

The Three Gorges Dam is a hydroelectric dam that spans the Yangtze River by the town of Sandouping, located in the Yiling District of Yichang, in Hubei province, China. The Three Gorges Dam is the world's largest power station in terms of installed capacity (20,300 MW) but is second to Itaipu Dam with regard to the generation of electricity annually.



The dam body was completed in 2006. Except for a ship lift, the originally planned components of the project were completed on October 30, 2008, when the 26th turbine in the shore plant began commercial operation. Each turbine has a capacity of 700 MW. Six additional turbines in the underground power plant are not expected to become fully operational until mid-2011. Coupling the dam's thirty-two main turbines with two smaller generators (50 MW each) to power the plant itself, the total electric generating capacity of the dam will eventually reach 22,500 MW.


As well as producing electricity, the dam increases the Yangtze River's shipping capacity, and reduces the potential for floods downstream by providing flood storage space. The Chinese government regards the project as a historic engineering, social and economic success, with the design of state-of-the-art large turbines, and a move toward limiting greenhouse gas emissions. However, the dam flooded archaeological and cultural sites and displaced some 1.3 million people, and is causing significant ecological changes, including an increased risk of landslides. The dam has been a controversial topic both in China and abroad.



The government estimates that the Three Gorges Dam project will cost 180 billion yuan (US$22.5 billion). By the end of 2008, spending had reached 148.365 billion yuan, among which 64.613 billion yuan was spent on construction, 68.557 billion yuan on relocating affected residents, and 15.195 billion yuan on financing. It is estimated that the construction cost will be recovered when the dam has generated 1,000 terawatt-hours (3,600 PJ) of electricity, yielding 250 billion yuan. Full cost recovery is expected to occur ten years after the dam starts full operation. Funding sources include the Three Gorges Dam Construction Fund, profits from the Gezhouba Dam, loans from the China Development Bank, loans from domestic and foreign commercial banks, corporate bonds, and revenue before and after the dam is fully operational. Additional charges were assessed as follows: Every province receiving power from the Three Gorges Dam has to pay ¥7.00 per MWh extra. Other provinces had to pay an additional charge of ¥4.00 per MWh. Tibet pays no surcharge.
