Concordia Antarctic Research Station

This was returned to me from the French/Italian Antarctic research station Concordia. It's marked with the stamp of the 40th Italian National Research Expedition and signed by Concordia's summer station leader station leader Riccardo Scipinotti. The position "Dome C" stamped at the bottom left gives the coordinates of the base. Dome C is one of several Antarctic ice domes which are large hills or caps of ice accumulation. This particular dome is 3300m thick.
