Atlantic Creek

Atlantic Creek is one of two rivers formed at the hydrologically unique site of the Parting of the Waters.

It originates directly on the continental divide from North Two Ocean Creek, which splits roughly in half at the Parting of the Waters.

[3] From the Parting of the Waters, it flows northeast over five miles of wilderness through the alpine valley of Two Ocean Pass and ends it short run into the Yellowstone River approximately 15 mi (24 km) southeast of Yellowstone Lake.

It then forms the borders of Nebraska, Iowa, Kansas, and Missouri before finally flowing east into the Mississippi River which empties into the Gulf of Mexico in Louisiana.

It flows further than the relatively short run of Atlantic Creek, emptying at Moran, Wyoming over 20 miles to the southwest into the Snake River below Jackson Lake Dam and ultimately the Pacific Ocean 1,353 mi (2,177 km) away via the Columbia River.

An 1894 drawing of Two Ocean Pass with a view to the northeast. Atlantic Creek exits the pass between the hills in the upper center part of the image. Pacific Creek exits to the southwest in the bottom center of the image. North Two Oceans Creek enters from the left top center of the image and divides into its two distributaries and South Two Ocean Creek enters from the right center of the image and is also shown dividing into two streams. Evermann Creek also enters the area from the west (left center, just above the tents).
