Darwin is, of course, best known for his scientific work on evolution. However, he also "dabbled" in other scientific fields, including geology.
Just to prove that even great minds sometimes get it wrong, it is worth reading about his conclusions on the "parallel roads" of Glen Roy, which he visited in 1838. To be fair to Darwin, he wasn't far wrong...
@fitheach That's fantastic.
Darwin did have more luck explaining how coral reefs formed, though [ https://en.wikipedia.org/wiki/The_Structure_and_Distribution_of_Coral_Reefs ]: "Darwin's theory that coral reefs formed as the islands and surrounding areas of crust subsided has been supported by modern investigations, and is no longer disputed"
Yeah, he discusses coral reefs in his book "The Voyage of the Beagle". The book as well as providing background to his work on evolution is a fascinating 19th century travelogue. Well worth reading. I hadn't realised Darwin was so accurate in his explanation of coral reef formation.
There are several damned lochs in the area which are used for the generation of hydro electric power. The water level of these lochs fluctuate markedly...
He was also the author of one of my all time favorite quotes:
"I hate a Barnacle as no man ever did before, not even a Sailor in a slow-sailing ship."
as the generation happens at a regular rate regardless of the amount of rain. These lochs often have obvious steps caused by the changing water levels. These steps look similar to the parallel roads seen by Darwin. In that sense he wasn't far wrong.
