A nice UNESCO cover from Switzerland, depicting a complete set issued in 2006 celebrating the "Swiss Alps Jungfrau-Aletsch", declared a world heritage site in 2001. This site encompasses one of the highest and most glaciated areas of the Alps, with peaks such as Eiger, Mönch, and Jungfrau. It provides a geomorphological record of the processes that shaped the High Alps, as well as a diverse habitat for animals and plants, developing in a succession following the retreat of the glaciers. The landscape has played an important role in the development of mountaineering and alpine tourism, as well as in literature and in arts. Originally listed in 2001, the boundaries of the site were expanded in 2007.
