Triple Divide Peak (8,020 feet (2,444 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. It is a hydrological apex of the North American continent, where the Great and Laurentian divides meet at the summit of the peak. Thus, all water that falls at this point can flow to the Pacific, Atlantic, or Arctic oceans (when Hudson Bay is considered an Arctic tributary), making the locale (and surrounding Waterton-Glacier International Peace Park) one of the few places on the Earth whose waters feed three oceans.
Rainfall on the western side of the peak enters Pacific Creek, which in turn enters Nyack Creek, the Middle Fork of the Flathead River, Clark Fork River, Pend Oreille River, and the Columbia River which empties into the Pacific Ocean at Astoria, Oregon. Flathead Lake and Lake Pend Oreille are also fed by this system of rivers, as well as some man-made lakes on the Columbia River.
The northeastern slope of the mountain sheds water into Hudson Bay Creek, which then drains into Medicine Owl Creek and Red Eagle Creek. It then empties into Saint Mary Lake, which feeds the St. Mary River, which in turn flows into the Oldman River, Saskatchewan River, and the Nelson River, which empties into Hudson Bay. (Some sources, however, consider Hudson Bay to be part of the Atlantic and, thus, Snow Dome – in Jasper National Park, on the border between Alberta and British Columbia, Canada – to be the continent's sole hydrological apex.) Lake Manitoba and Lake Winnipegosis, also in Manitoba, are part of the Hudson Bay watershed as well, feeding Lake Winnipeg via Dauphin River.
Moisture on the southeastern slopes feeds into Atlantic Creek, which in turn enters the North Fork of Cut Bank Creek, Marias River, Missouri River, which joins the Mississippi River north of St. Louis, Missouri, before emptying into the Gulf of Mexico near New Orleans. This ultimately reaches the Atlantic.
