Powder River (Wyoming and Montana) Powder River is a tributary of the Yellowstone River, approximately 375 mi long in northeastern Wyoming and southeastern Montana in the United States. It drains an area historically known as the Powder River Country on the high plains east of the Bighorn Mountains.
Elk Creek (West Virginia) Elk Creek is a tributary of the West Fork River, 29 mi long, in north-central West Virginia in the United States. Via the West Fork, Monongahela and Ohio Rivers, it is part of the watershed of the Mississippi River, draining an area of 121 sqmi on the unglaciated portion of the Allegheny Plateau. The stream is believed to have been named by an 18th-century trapper and hunter named John Simpson, who encountered herds of elk along the stream.
