George Hedges (1952-2009), a Hollywood litigator, and filmmaker Nicholas Clapp, participated in the find. In 1992 a team of investigators announced the discovery of the long lost Arabian city of Ubar. The event was later cited by Muhammad in the Quran. The Arabian city of Ubar, disappeared in the early 6th century. The Al-Murrah, the Rashidi, and other Bedouins have wandered the eastern region, but the advent of oil has forced the settlement of most of the Bedouin.Next Prev Page: 1 2 3 4 5 6 7 8 9 10 11. The al-Ghawar oil field (discovered in 1948) is one of the largest in the world. The east area has many oil and gas fields. Ubar was famous in ancient times as a city of great wealth that produced frankincense. American archaeologists located the ruins with radar images taken by the ill-fated space shuttle Challenger. The ancient fort is believed to be the legendary lost city of Ubar. In 1992, the “Atlantis of the Rub' al Khali” was uncovered from a layer of sand. There are also numerous insects, snakes, and other animals. Bones of animals and flint arrowheads have been found in a number of locations. Many desert plants do grow when the rare rains come. The Rub' al-Khali was much wetter in prehistoric times. These rains can stimulate the growth of vegetation lasting up to three years. The rains that do fall are either in the northern area from winter rains or from monsoon rains off the ARABIAN SEA. The humidity is usually quite low. Very little fauna and flora are found in the Empty Quarter. Temperatures in the Rub' al-Khali can reach 130 degrees F (50 degrees C) or higher. Most of the Rub' al-Khali is uninhabited and much of it is some of the driest land on Earth. In Oman, this drainage creates a very dangerous region of quicksands and poisonous bogs called the Umm al Samim. In the south, the water from the wadis flowing off the coastal plateau that borders the entire southern end of the Arabian peninsula disappears in the sands of the Rub' al-Khali.
The eastern area is relatively level but covered with salt flats (sabkhas) in many areas. The sabkhas can be quagmires. The eastern part of the Rub' al-Khali fills a broad, shallow basin that slopes toward the southern shores of the PERSIAN GULF. Some of the crescent dunes have fishhook shapes at their end or are like scimitars. The dunes in this area are also often crescent-shaped. In the north-central area of the Rub' al-Khali is the great Wabar impact crater created by a large meteorite. A number of meteors have been found in the vast sand dunes. In the western area of the Rub' al-Khali are many linear dunes that run for many miles in a northeast-southwest direction. The wind forms the sand dunes into many shapes.Īerial and space photography have shown that the dunes are arranged in belts, but take many shapes. During the February to March monsoon season, the wind blows mainly from the south. It also causes sandtorms in the eastern part of Saudi Arabia.
The shamal grows in force each day with the heating of the air. A northwesterly wind, called the shamal, shapes the dunes making them into an active sea of shifting sand. The Rub' al-Khali is connected to the Nafud sand desert in northern Saudi Arabia by the Dahna belt of sand dunes. The Rub' al-Khali slopes from an altitude of about 3,300 ft (1,006 m) in the west to close to sea level in the east. In the east, the Rub' al-Khali overlaps the boundaries of the UNITED ARAB EMIRATES. While most of it is in Saudi Arabia, the southern boundary overlaps the borders of YEMEN and OMAN. It is about 700 mi (1,127 km) long east to west and about 400 mi (644 km) wide north to south. The northern boundary of the Rub' al-Khali is the central plateau (Nedj) of Saudi Arabia. It covers about a fourth of that country. Most of the Rub' al-Khali is in southern and southeastern SAUDI ARABIA. It is somewhat smaller than TEXAS or about as large as FRANCE together with BELGIUM and Holland. THE RUB' AL-KHALI (Arabic for “Empty Quarter”) is located in the southern part of the Arabian Desert. The Al-Murrah Bedouin, who roam its southern edges call it the ar-Ramlah, the “sand.” It covers an area of about 250,000 square mi (647,500 square km).
