range of the Atlas Mountains in North Africa, extending about 1,000 miles (1,600 km) from eastern Morocco through Algeria to Tunisia. In Morocco, from Ceuta east to Melilla (150 miles 【240 km】), the Er-Rif mountain range of the Tell Atlas faces the Mediterranean Sea, and there, as along the whole coast eastward to Cape Bon in Tunisia, many rugged rocks rise dramatically above the general level. In Algeria there are five chief ranges, the highest being the Great Kabylie, which reaches a height of 7,572 feet (2,308 m) at Lalla Khedidja. In Tunisia the Tell comprises coastal hills and an inland plateau, with high points rising to 4,500 feet (1,370 m).
