The Aletsch Glacier is part of the UNESCO World Heritage Site that also includes the Jungfrau and the Bietschhorn.
"This is the largest glacier in the Alps. Covers more than 120 square kilometres (more than 45 square miles) in southern Switzerland. It descends round the south of the Jungfrau into the valley of the Upper Rhône; at its eastern extremity lies a glacier lake, Lake Märjelen (2,350 meters/7,711 feet). To the west rises Aletschhorn (4,195 meters/13,763 feet). The Rhône River flows along the southern flank of the mountains." - in: wikipedia.
