Mountain range in Iran.
The Zagros mountain range is the largest in Iran, stretching for 1,400 miles (2,253 km) from Armenia in the former U.S.S.R. in the northwest to the Persian Gulf in the south, and thence eastward to Baluchistan. It consists of a number of parallel ranges, the highest peak of which rises to 14,000 feet (4,270 m). It separates the Iranian plateau from the plains of Mesopotamia and Iraq in the west and the Persian Gulf in the south. Together with the Elburz (also known as Alborz) ranges in the north, the Zagros was formed from the Paleozoic to the Pliocene period.
