It is, however, another cautionary note to folks who think Darwin was a total genius who never got anything wrong ~ in this instance his uniformitarian viewpoints (gradual changes over time doing massive work) got the best of him.
Still, glacial rafting from mountain ranges is a recent enough finding that Darwin had never heard of it.
I seriously doubt Darwin wanted to climb up Andean mountains to see ice.
Within the last year or so the "uniformitarian" view regarding the way paint is mixed also collapsed in the face of computer models that correctly predict the outcome of various ways of mixing.
Remember, Darwin didn't know about DNA. He didn't know what a computer chip was or how it worked. He was rusty with calculus. And, when he was in fat city and ate bread with his meals he spent the next three days in the toilet unloading his bowels on a continuing basis. He knew alimentary piece only in the more primitive countryside where they ate oatmeal!
