This is a place I learned about many years ago, but will probably never have the opportunity to visit. The Google Map image above includes the approximate location where North Two Ocean Creek, splits into Pacific Creek, which flows to the Pacific Ocean via the Snake and Columbia rivers and Atlantic Creek, which flows to the Gulf of Mexico via the Yellowstone, Missouri, and Mississippi rivers. There are other continental divides throughout the world, but this is the only place that I am aware of where a significant drainage splits to different oceans.
According the the National Park Service, his is the point at which the Pacific Drainage cutthroat trout crossed the divide into the Mississippi Drainage.
This site includes maps and several photos of the point where North Two Ocean Creek splits.
