Headed north from Henry's Lake and had all country roads to reach Three Forks, MT. This town is part of
Lewis and Clarke's expedition to discover the west and I read somewhere in town that it was where Sacagawea recognized and was reunited with her brother during the negotiations with the natives in the area for food and horses.
Three Forks is named for the three rivers that converge just northeast of the town to form the Missouri River. They are the Jefferson, Madison, and Gallatin Rivers, named by Lewis and Clark after two presidents and a treasury secretary. From Three Forks the Missouri River flows north and after traveling 2,565 miles reaches the Mississippi River. The Missouri River is the longest single river in North American and drains about 1/6 of the North American Continent.
