Jewish Babylonian, Syriac, and Islamic traditions identify Mount Judi or Qardu as a peak near the town of Jazirat ibn Umar (modern Cizre), at the headwaters of the Tigris, near the modern Syrian-Turkish border. Arab historian Al-Masudi (d. 956), reported that the spot where the ark came to rest could be seen in his time. Al-Mas'udi locates Jabal Judi at 80 parasangs from the Tigris. Mount Judi was historically located in the province of Corduene, south of Lake Van. The mountains of this region, where Syria, Turkey, Iraq and Iran meet, are referred to as the 'Zagros'.
