GEORGIA, STRAIT OF

narrow passage of the eastern North Pacific between the central east coast of Vancouver Island and the southwest mainland of British Columbia, Canada. It averages 138 miles (222 km) in length and 17 miles (28 km) in width. To the north the strait ends in a jumble of islands separating it from Johnstone and Queen Charlotte straits farther north. The southern end is marked by the San Juan Islands of the U.S. state of Washington. Texada and Lasqueti islands are the largest within the strait, which has a midchannel depth of 9001,200 feet (275370 m). The mainland coast is cut by many inlets, one of which is the mouth of the Fraser River and the site of Vancouver. The Fraser's outflow aids a general counterclockwise movement of water in the strait, known locally as the Gulf. The strait forms a link in the scenic and sheltered Inside Passage sea route between Seattle, Wash., and Skagway, Alaska. Its name, honouring George III, was conferred by Captain George Vancouver in 1792. The economy The Georgian economy includes diversified and mechanized agriculture alongside a well-developed industrial base. Agriculture accounts for about half of the gross domestic product and employs about one-fourth of the labour force; the industry and service sectors each employ about one-fifth of the labour force. After independence the Georgian economy contracted sharply, owing to political instability (which discouraged foreign investment), the loss of favourable trading relationships with the states of the former Soviet Union, and the civil unrest in Abkhazia and South Ossetia, where key pipelines and transport links were sabotaged or blockaded. Georgia sought to transform its command economy into one organized on market principles: prices were liberalized, the banking system reformed, and some state enterprises and retail establishments privatized. Resources The interior of Georgia has coal deposits (notably at Tqvarch'eli and Tqibuli), petroleum (at Kazeti), and a variety of other resources ranging from peat to marble. The manganese deposits of Chiat'ura rival those of India, Brazil, and Ghana in quantity and quality. Its waterpower resources are also considerable. The deepest and most powerful rivers for hydroelectric purposes are the Rioni and its tributaries, the Inguri, Kodori, and Bzyb. Such western rivers account for three-fourths of the total capacity, with the eastern Kura, Aragvi, Alazani, and Khrami accounting for the rest. Oil deposits have been located near Bat'umi and Pot'i under the Black Sea. The land Relief, drainage, and soils With the notable exception of the fertile plain of the Kolkhida Lowlandancient Colchis, where the legendary Argonauts sought the Golden Fleecethe Georgian terrain is largely mountainous, and more than a third is covered by forest or brushwood. There is a remarkable variety of landscape, ranging from the subtropical Black Sea shores to the ice and snow of the crest line of the Caucasus. Such contrasts are made more noteworthy by the country's relatively small area. The rugged Georgia terrain may be divided into three bands, all running from east to west. To the north lies the wall of the Greater Caucasus range, consisting of a series of parallel and transverse mountain belts rising eastward and often separated by deep, wild gorges. Spectacular crest-line peaks include those of Mount Shkhara, which at 16,627 feet (5,068 metres) is the highest point in Georgia, and Mounts Rustaveli, Tetnuld, and Ushba, all of which are above 15,000 feet. The cone of the extinct Mkinvari (Kazbek) volcano dominates the northernmost Bokovoy range from a height of 16,512 feet. A number of important spurs extend in a southward direction from the central range, including those of the Lomis and Kartli (Kartalinian) ranges at right angles to the general Caucasian trend. From the ice-clad flanks of these desolately beautiful high regions flow many streams and rivers. The southern slopes of the Greater Caucasus merge into a second band, consisting of central lowlands formed on a great structural depression. The Kolkhida Lowland, near the shores of the Black Sea, is covered by a thick layer of river-borne deposits accumulated over thousands of years. Rushing down from the Greater Caucasus, the major rivers of western Georgia, the Inguri, Rioni, and Kodori, flow over a broad area to the sea. The Kolkhida Lowland was formerly an almost continually stagnant swamp. In a great development program, drainage canals and embankments along the rivers were constructed and afforestation plans introduced; the region has become of prime importance through the cultivation of subtropical and other commercial crops. To the east the structural trough is crossed by the Meskhet and Likh ranges, linking the Greater and Lesser Caucasus and marking the watershed between the basins of the Black and Caspian seas. In central Georgia, between the cities of Khashuri and Mts'khet'a (the ancient capital), lies the inner high plateau known as the Kartli (Kartalinian) Plain. Surrounded by mountains to the north, south, east, and west and covered for the most part by deposits of the loess type, this plateau extends along the Kura (Mtkvari) River and its tributaries. The southern band of Georgian territory is marked by the ranges and plateaus of the Lesser Caucasus, which rise beyond a narrow, swampy coastal plain to reach 10,830 feet in the peak of Didi-Abuli. A variety of soils are found in Georgia, ranging from gray-brown and saline semidesert types to richer red earths and podzols. Artificial improvements add to the diversity. Climate The Caucasian barrier protects Georgia from cold air intrusions from the north, while the country is open to the constant influence of warm, moist air from the Black Sea. Western Georgia has a humid subtropical, maritime climate, while eastern Georgia has a range of climate varying from moderately humid to a dry subtropical type. There also are marked elevation zones. The Kolkhida Lowland, for example, has a subtropical character up to about 1,600 to 2,000 feet, with a zone of moist, moderately warm climate lying just above; still higher is a belt of cold, wet winters and cool summers. Above about 6,600 to 7,200 feet there is an alpine climatic zone, lacking any true summer; above 11,200 to 11,500 feet snow and ice are present year-round. In eastern Georgia, farther inland, temperatures are lower than in the western portions at the same altitude. Western Georgia has heavy rainfall throughout the year, totaling 40 to 100 inches (1,000 to 2,500 millimetres) and reaching a maximum in autumn and winter. Southern Kolkhida receives the most rain, and humidity decreases to the north and east. Winter in this region is mild and warm; in regions below about 2,000 to 2,300 feet, the mean January temperature never falls below 32 F (0 C), and relatively warm, sunny winter weather persists in the coastal regions, where temperatures average about 41 F (5 C). Summer temperatures average about 71 F (22 C). In eastern Georgia, precipitation decreases with distance from the sea, reaching 16 to 28 inches in the plains and foothills but increasing to double this amount in the mountains. The southeastern regions are the driest areas, and winter is the driest season; the rainfall maximum occurs at the end of spring. The highest lowland temperatures occur in July (about 77 F ), while average January temperatures over most of the region range from 32 to 37 F (0 to 3 C). The people The likelihood is great that the Georgians (whose name for themselves is Kartveli; Georgian derived from the Persian name for them, Gorj) have always lived in this region, known to them as Sakartvelo. Ethnically, contemporary Georgia is not homogeneous but reflects the intermixtures and successions of the Caucasus region. About seven-tenths of the people are Georgians; the rest consists of Armenians, Russians, Azerbaijanis, and smaller numbers of Ossetes, Greeks, Abkhazians, and other minor groups. The Georgian language is a member of the Kartvelian (South Caucasian) family of languages. It has its own alphabet, which is thought to have evolved about the 5th century AD, and there are many dialects. A number of other Caucasian languages are spoken by minority groups; many are unwritten. Many Georgians are members of the Georgian Orthodox church, an autocephalous Eastern Orthodox church. In addition, there are Muslim, Russian Orthodox, Armenian Apostolic, and Jewish communities. The Georgians are a proud people with an ancient culture. They have through the ages been noted as warriors as well as for their hospitality, love of life, lively intelligence, sense of humour, and reputed longevity (although statistical data do not support this latter assertion).
