North of the Mountains is Dzungaria with its central Gurbantünggüt Desert, Urumchi the capital and the Karamay oil fields. The Kulja territory is the upper basin of the Ili River and opens out onto the Kazakh steppe with several roads eastward. The Dzungarian Gate was once a migration route and is now a road and rail crossing. Tacheng or Tarbaghatay is a road crossing and former trading post.
