Louis Agassiz

THERE are phenomena in nature which give the clew to so many of its mysteries, that their correct interpretation
leads at once to broad generalizations and to the rapid advance of science in new directions. The "parallel roads"
of Glen, Roy offer such a problem. For half a century they have been the subject of patient investigation and the
boldest speculation. … The theory of formation …by continental upheavals and subsidences, advocated by
Sir Charles Lyell and Charles Darwin … has been duly discussed with reference to this difficult case, … but the matter
still remains a mooted point … I propose here to reconsider the facts of the case, and to present anew my own explanation
of them, now more than twenty years old, but which I have never had an opportunity of publishing in detail under a popular
form, though it appeared in the scientific journals of the day.
