Yugoslavia (former) Topography
Sources: The Library of Congress Country Studies; CIA World Factbook
Rugged mountains dominate the 255,892 square kilometers of Yugoslavia. Mountains separate the fertile inland plain from a narrow, rocky Adriatic coastline. Yugoslavia's three main mountainous regions occupy about 60 percent of its territory. The Julian Alps of Slovenia, an extension of the Italian and Austrian alps, include Yugoslavia's highest peaks. The Dinaric Alps rise dramatically along the entire 640-kilometer Adriatic coast. Finally, spurs extend southward from the Carpathian and Balkan mountains through Serbia from the Danube River's Iron Gate near the Romanian-Bulgarian border, intersecting with the Dinaric Alps in Macedonia (see Drainage Systems , this ch.).
The composition of Yugoslavia's mountains varies. The Dinaric Alps, like the offshore Adriatic islands, are chiefly cracked limestone strata that form long valleys and contain topographical oddities such as magnificent caves, disappearing rivers, and a freshwater lake (on the north Adriatic island of Cres) deeper than the Adriatic seabed. In some areas east of the coast, erosion of the limestone has exposed the crystalline rock outlayers of the Rhodope massif, which is the primeval core of the Balkan Peninsula. From Bosnia southeastward, areas of crystalline rock are interspersed with alluvial sedimentary rock. Serbia's mountains contain a variety of rock types, including volcanic rock and exposed crystalline formations. Geological fault lines in southern Yugoslavia have caused occasional earthquakes; the most serious in recent times killed over 1,000 people at Skopje in 1963.
North and west of Belgrade are the Pannonian Plains, which include all of the Serbian province of Vojvodina. These plains wwer the floor of a huge inland sea during the Tertiary Period (65 millon to 2.5 million years ago). Here eons of sedimentary and windblown deposits have created layers of fertile soil that are over 160 meters deep in some places.
Yugoslavia possesses about 2100 kilometers of convoluted Adriatic coastline, not including its many islands. From the coast, access inland is easiest through four passages. The Postojna Gate, used for millennia by merchants and armies crossing between the Adriatic and Central Europe, is Yugoslavia's northernmost passage through the coastal mountains. Farther south, the Neretva River is a centuries-old trading link between the Adriatic and Bosnia. Below the Neretva, the Gulf of Kotor is a spectacular fjord long considered a strategic port. Finally, the port of Bar connects with the interior of Montenegro and Serbia by means of the Belgrade-Bar Railway, giving Serbia access to the Adriatic.
