Rivers in Wyoming

This remote river crossing was a popular campground on American westward expansion trails, and a former Pony Express station.

This canyon is named for a unique geologic formation where the river vanishes underground near the mouth of the canyon and reappears farther down.

Creek water that starts here has a 50/50 chance of ending up in the Atlantic or the Pacific.

The only natural lake in the world that drains into both the Atlantic and Pacific Oceans.
