The true source of the Missouri river, Montana-Idaho, USA

The source of a large river system, for example, the Missouri-Mississippi river, the largest in the United States, is often taken as the location of the uppermost spring in the farthest tributary. Under this optic, the source of the Missouri river would be Brower's Spring (Fig. 2), located in the headwaters of Hell Roaring Creek, in southwestern Montana. The spring is named after Jacob V. Brower, who in 1896 declared it to be the source of the Missouri river in his book The Missouri river and its utmost source. However, the name Brower's Spring is not listed as an official name on the Geographic Names Information System maintained by the U.S. Geological Survey.
