Drygalski Glacier (64°43'S 60°44'W) is a broad glacier, 20 miles (32 km) long and 15 miles (24 km) wide at its head, which flows from Herbert Plateau southeast between Ruth Ridge and Kyustendil Ridge, and enters Solari Bay immediately north of Sentinel Nunatak on Nordenskjöld Coast, the east coast of Graham Land, Antarctica. It was discovered in 1902 by the Swedish Antarctic Expedition, under Otto Nordenskiöld, and named "Drygalski Bay" after Professor Erich von Drygalski.
