Camp Three Forks is located three (3) miles from the City of Three Forks. Three Forks, Montana is aptly named. This is the location of the confluence of the Jefferson, Gallatin and Madison Rivers that form the mighty Missouri River. These waters then flow north from Three Forks and wind all the way to the Mississippi river some 2,565 miles distant. The Missouri River, the longest in North America, drains approximately one-sixth of the North American continent.
