Triple points

(in its current unapproved working edition only of ''Limits of Oceans and Seas'') defines the Hudson Bay, with its outlet extending from 62.5 to 66.5 degrees north (just a few miles south of the Arctic Circle) as being part of the Arctic Ocean, specifically "Arctic Ocean Subdivision 9.11." This hydrological apex of North America status of Triple Divide Peak is the main reason behind the designation of Waterton-Glacier International Peace Park as the "Crown of the Continent" of North America. The summit of the peak is the world's only oceanic triple divide point. Discounting

tributaries are never within proximity of each other. Thus, North America's status of having a single location draining into three oceans is unique in the world. Sources differ, however, on whether Hudson Bay, entirely south of the Arctic Circle, is part of the Atlantic or Arctic Ocean. Hudson Bay's water budget connects to the Atlantic more than to the Arctic Ocean. The channels to the north of Hudson Bay are largely cut off by Baffin Island from the Arctic, so much of the water that enters it mixes with the Atlantic to the east via

Such basins can be, and routinely are, assigned to one side of the Divide or the other by their lowest perimeter pass; in other words, an assignment is made by determining how the drainage would occur if the basin were to be progressively filled with water until it overflowed.

topographic maps of the United States generally show only the main Divide as determined by the overflow rule. Among other things, this eliminates the need to trace out the boundary for a basin that is very shallow and has a nebulous rim, such as the San Luis Closed Basin in Colorado and the basin of the lost streams of Idaho. Another rare exception occurs when a stream near a divide splits and flows in both directions, or a lake straddling the divide overflows in both directions. Examples of these are, respectively, North Two Ocean Creek and Isa Lake, both located on the Continental Divide in Wyoming. The
