Three Forks
The Gallatin River meets the Madison/Jefferson Rivers, forming the true Missouri River, above and top right. Captain Clark would follow the Gallatin River, southeast, on his return trip in 1806, right and top left. The Corps stayed at the Missouri Headwaters, from July 27th through the 29th, 1805. Clark and his party had arrived on the 25th. Clark's party explored the Jefferson fork up 12 miles to determine if it was the main river.
