The Lebanon is the highest and most rugged and developed region in Syria, and the main ridge for two-thirds of its length rises to sub-Alpine heights. There is a group of peaks in the north, the highest being Dahr el-Kadhib (10,018 ft.), and southwards Jebel Sunnin (8,650 ft.) marks the centre of the range. The eastern flank of the northern part is separated from the main chain by an elevated valley with an altitude of 5,000 ft. South of this the eastern slopes are unsuited to occupation; but the western slopes, although intersected by many gorges, have a perennial water supply, and are studded with villages. In general the northern part of Lebanon is less fertile than the southern.
South of the Litani the range continues southward through southern Syria to the Sinaitic plateau, its continuity only being interrupted by the plain of Esdraelon, which forms the easiest entrance to the interior of the country. The watershed in general is so situated that less than one-third of the country lies on its eastern side. The western slope is long and gradual, and merges into plains near the coast, but the eastern slope is steep and precipitous, especially towards its southern end.
South of the Esdraelon plain is the open hill system of Samaria, with the ridge of Carmel (altitude 1,810 ft.), and then the range, continuing parallel with the Jordan valley, passes imperceptibly into the compact tableland of Judaea.
In Judaea the highlands attain their greatest height (about 3,300 ft.) just north of Hebron, and then descend gradually towards the desert and the Egyptian frontier. The ridge as a whole varies in width from 14 to 17 miles, and its general character, especially in the south, is that of a stony upland with rough scrub and thorn vegetation, much broken up by deep valleys running both eastward and westward.
Central Depression.—With a few interruptions this feature is clearly defined from the base of the Anti-Taurus to the Gulf of Akaba. At the northern end it
