The picture postcard scene at the headwaters is totally manufactured. The real character of the original Mississippi River as it left Lake Itasca was a low wide marsh with no specific river channel. Around 1900, a group of local loggers decided that it was not proper that such a great river get its start by running through a muddy swamp. So, the dug a new channel to bypass the marsh. That is the channel that we see today. This foot bridge spans both the new channel and the remainder of the marsh, and the two channels join just downstream of this bridge.
