Which river flows into both Atlantic and Pacific?

Question

Answer 1

Not a single river but we can say single water body i.e. Parting of the Waters.

There's a natural spring in Yellowstone National Park in Wyoming that flows in 2 directions. One ultimately connects to the Mississippi River, which flows into the Gulf of Mexico. The other connects to the Columbia River, which flows into the Pacific Ocean. It's a natural wonder called the Parting of the Waters.
