The Fork in the River

Monday, June 3, 1805. Today we have to stop because there is a fork in the river and we don't know which way to go. The Captains are going to split us in two and one groups going to go down one of the rivers and the other is going to go down the other. We all think the muddy looking one is the Missouri River, except for the Captains. They think that the other River is the Missouri River because it is clear and that mountain water should be clear. I think its the other river because the whole way down the Missouri the Missouri as been murky and muddy.
