This Illustration of the Glacier Systems of the Alps by Alexander Keith Johnston was first published 1848 in The Physical Atlas.

In the Miocene Epoch the mountains underwent severe erosion because of glaciation,[34] which was noted in the mid-19th century by naturalist

Louis Agassiz who presented a paper proclaiming the Alps were covered in ice at various intervals—a theory he formed when studying rocks

near his Neuchâtel home which he believed originated to the west in the Bernese Oberland. Because of his work he came to be known as the

“father of the ice-age concept” although other naturalists before him put forth similar ideas.[47]
