Susten Pass (2,264 m) built from 1938?1945, is located in the Swiss Alps, and connects Innertkirchen in the canton of Bern, with Wassen in the canton of Uri. A 300 metres long tunnel crosses the pass at 2,224 metres. The pass is popular with tourists, especially for the views of the Stein Glacier on the south side. The Stein Glacier (Steingletscher) is a 4 km long glacier situated in the Urner Alps in the canton of Berne in Switzerland. In 1973 it had an area of 6.06 km². Glacial ice is the largest reservoir of freshwater on Earth, and many glaciers store water during one season and release it later as meltwater, a water source that is especially important for plants, animals and human uses when other sources may be hard to come by.
