LC... Great stuff on the three rivers. I remember reading about the challenge of the choice. Trying to recall, didn't they divide here and either Lewis or Clark went north following one of the rivers to confirm it wasn't the right one?
Great image of the Missouri where one can jump across it. Is possible to do the same in Colorado, jumping across the Rio Grande, Arkansas, Colorado, and the North/South Plattes where they are a mere three feet across.
