Triple Divide Peak (8,025 feet or 2,446 metres) is located in the Lewis Range, part of the Rocky Mountains in North America.

In the case of Antarctica, there is no freely flowing water due to ice sheets and permafrost.

So Triple Divide Peak is the only single point on Earth from which water flows into three distinct oceans.

Under this stipulation, because the bay is fed by drainage from Triple Divide Peak, Snow Dome, which is the triple divide between Hudson Bay, the Arctic Ocean, and Pacific Ocean, is world’s sole hydrological apex.

Moisture on the southeastern slopes feeds into Atlantic Creek, which in turn enters the North Fork of Cut Bank Creek, Cut Bank Creek, the Marias River, and the Missouri River which joins the Mississippi River before emptying into the Atlantic's Gulf of Mexico near New Orleans.
