一條弧形如同一輪新月一樣縱深在廢土這片大地上的峽谷，它名為新月。 新月峽谷中間本來有一條架空的火車道，後來不知道因何原因而坍塌。 從西側進入峽谷中，可以遠遠見到三個火車的集裝箱架成一個倒V字形。 裡面到處都是半埋的核廢料桶，一輛翻倒的大貨車靜靜躺在一旁，裡面裝滿了核廢料桶 再往裡面走，兩輛疊在一起的報廢車輛形成一道古怪的風景。 如果你沿著峽谷上面走，可以見到半節紅色火車箱懸在火車道上，搖搖欲墜。

- Legate's camp.[已核实] When standing near the entrance (Facing away from Morning Star Cavern), on the right-hand side of the canyon you should be able to take the rocks up and out of the map with very little amount of jumping involved.
