Henry Rowe Schoolcraft,
Narrative of an Expedition Through the Upper Mississippi to Itasca Lake…
“ Six or seven hundred feet would not appear to be an extravagant estimate for the entire fall. The river itself is a perfect torrent; often on looking down its channel, there are wreaths of foam constituting a brilliant vista, overhung with foliage. It would never be used at all, for the purposes of the trade, were it not, that there is much water on the rapids, so that experienced men can conduct loaded canoes both up and down them. The river might appropriately be called Rapid, or Mad River, or almost any thing else, but by its popular name of Brulé. ”
