North Fork Flathead River

[1] The river originates in a valley northeast of Lake Koocanusa in the Clark Range, and flows west.

It then meets the Continental Divide and turns south, winding through a broad glacial valley.

The river then crosses the Canada–US border into the state of Montana, where it begins to delineate the western boundary of Glacier National Park.

Water in the BC section remains relatively pure as there are no permanent residents or livestock in this drainage north of the border.
