Mer de Glace Glacier

The Mer de Glace in Chamonix is the largest glacier in France. It is 6.8 miles long and 1,300 ft thick according to Wikipedia. The Mer de Glace has lost over 500 ft in depth (roughly the height of a 40-story building) since 1900. Markers along the path down to the glacier indicate the height of the glacier at different periods in history and give visitors get a stark reminder of how dramatically this majestic "sea of ice" is retreating.
