The Lajat, also spelled Lejat, Lajah, el-Leja or Laja, is the largest lava field in southern Syria, spanning some 900 square kilometers. Located about 50 kilometers (31 mi) southeast of Damascus, the Lajat borders the Hauran plain to the west and the foothills of Jabal al-Druze to the south. The average elevation is between 600 and 700 meters above sea level, with the highest volcanic cone being 1,159 meters above sea level. Receiving little annual rainfall, the Lajat is largely barren, though there are scattered patches of arable land in some of its depressions.
