Shallow Valley

Green Valley is a valley located on Earth. Following the Second Nuclear Apocalypse, it remains the sole place on humanity's home planet populated by vegetation reminiscent of that which existed prior to Praimfaya.

Description
The valley is located on Earth, and is lush, full of vegetation. According to Clarke Griffin, the rest of Earth remains biologically ruined due to having undergone another nuclear cataclysm. Regular precipitation is seen falling above the valley, indicating no signs of any apocalypse.

History
Clarke, along with her foster daughter, Madi, travels to the valley in an attempt to communicate with Bellamy and the Ark. She is seen as having little hope of actually achieving her purpose. All of that changes when a ship is seen entering Earth's orbit above the valley, making Clarke assume it was carrying Raven and the others. Enthusiastic, she rushes over to Madi, who notices the ship's size to be far bigger than what Clarke had anticipated it to be. Immediately thereafter, Clarke orders Madi to bring her her rifle, which she uses to inspect the ship, which is revealed to be carrying prisoners from the Asteroid Belt, commissioned by the Eligi Corporation.
