Meriwether Lewis was known to comment on the falls:
. . . hearing a tremendious roaring above me I continued. . . a few hundred yards further and was again presented by one of the most bea[utiful]objects in nature, a cascade of about fifty feet perpendicular stre[t]ching at [right angles] across the river from side to side to the distance of at least a quarter of a mile. here the river pitches over a shelving rock, with an edge as regular and streight as if formed by art, without a nich[e] or br[eak] in it; the water descends in one even and uninterrupted sheet . . .
The waterfall was named “Beautiful Cascade” and later “Handsom[e] Falls” by Lewis, but was given its present name by Thomas B. Roberts, a railroad engineer, in 1872. — From Wikipedia
