Amnicon

Many years back (long before being a boater), I swam in the pool at the base of the larger falls in the park. As briefly mentioned in the text above, my recollection is that the pool actually contains multiple 'splines' of rock parallel to the face of the falls (perpendicular to the flow of the river). Walking/swimming toward the falls from below, one goes from knee-deep to over-your-head to knee-deep to over-your-head almost literally from one 'step' forward to the next. (Essentially a rather exaggerated, 'corrugated' bottom.) Thus, depending on where one lands (and how deep they go), there is potential for great pain here.
