Morteratsch Glacier
Graubünden
Morteratsch Glacier, located in the Bernina Range of the Swiss canton of Graubünden, is the largest glacier in the Eastern Alps by volume, with about 1.2 cubic kilometers. It stretches approximately 6.2 kilometers in length, making it the third longest glacier in the Eastern Alps after Austria's Pasterze and Gepatschferner glaciers. The glacier has been extensively studied since 1878, revealing a retreat of about 2.5 kilometers due to global warming. Morteratsch Glacier was once connected to the Pers Glacier, but since 2015 they have been separate. The surrounding area features a glacier trail with 20 educational stations explaining glaciology, geomorphology, and local vegetation, alongside signs documenting the glacier's ongoing retreat. The glacier lies in a dramatic alpine valley surrounded by peaks over 3,000 meters, including Piz Morteratsch and Piz Bernina. Its southern edge forms part of the Swiss-Italian border. The glacier’s history and natural changes are emblematic of broader Alpine environmental shifts and provide a unique opportunity for visitors to witness glacial dynamics firsthand. A spring ski route from Diavolezza crosses the glacier, adding to its recreational appeal.
