Panoramic views of Gornergletscher around 1900 and 2018 from Gornergrat. The ice surface has sunk so much that most of the glacier tongue lies below the lower edge of the picture. The small mountain glacier at Schwärze (left of centre) has almost completely disappeared (old panorama: ETH-Bibliothek Zürich, Bildarchiv, Fotograf: Unbekannt, Hs_1458-GK-B014-0000-0008, CC BY-SA 4.0, 2018: Alean).
