“ The Whirlpool at the end of the rapids is a most extraordinary formation. The torrent runs into an oblong pool, within an elliptical basin, the outlet being at the side through a narrow gorge not two hundred and fifty feet wide, above which the rocky walls tower for three hundred feet. Into this basin the waters rush from the rapids, their current pushing to its farthest edge, and then, rebuffed by the bank of the abyss, returning in an eddy on either hand. ”
