From this split, Two Ocean Creek waters flow either 3,488 miles (5,613 km) to the Atlantic Ocean via Atlantic Creek and the Yellowstone, Missouri and Mississippi Rivers, or 1,353 miles (2,177 km) to the Pacific Ocean via Pacific Creek and the Snake and Columbia Rivers. In the marshy area of Two Ocean Pass adjacent to Parting of the Waters, water actually covers the Continental Divide such that a fish could swim from the Pacific Ocean to the Atlantic Ocean drainages. In fact, it is thought that this was the pass that provided the route for Yellowstone cutthroat trout to migrate from the Snake River (Pacific) to Yellowstone River (Atlantic) drainages.[3][4]
