    The Swiss have "stacked" tropo maps and you can do a bit of "time travel" as you progress through the layers. The growth of towns and the shrinkage of glaciers is readily apparent: Time Machine

    It appears that the Rhone glacier went all the way down to the valley floor until sometime in the late '60s.
