"The ""glaciers"" have greatly impressed the collective imagination of the Alps and their shrinking forms, in landscape terms, is nothing short of a crime of lèse-majesté. The Gébroulaz glacier is one of the best monitored in France, with certain measures such as topographical maps dating back as far as the twentieth century. The annual measurements, useful for understanding, do not however prevent the glacier from decreasing in surface and thickness, depositing lateral moraines as here in its central zone."
