Hello there, I hope I could help you. I can not see the map but: Zagros stretch across western Iran and are located next to the Khuzestan Plain. It is the longest mountain range of Iraq and Iran, extending over 1500 kilometers.

Its in the national history museum and you can't se the original because its locked away in a vault
