Powder River Basin

The Powder River Basin is a geographical feature on Earth, located within the American states of Wyoming and Montana.

The name of the area derives from the Powder River, presumably consisting of water, which flows through it.

Fiction

Megatron, desperately low on fuel, ended up in the eastern Wyoming part of the Powder River Basin. I, Robot-Master!

The Decepticons built their Wyoming base in a coal strip mine within the region, with additional fortifications built by the Constructicons. Command Performances!
