Hiawatha Glacier

Hiawatha Glacier in northwest Greenland, with its terminus in Inglefield Land, was mapped in 1922 by Danish geologist Lauge Koch, who noted its glacier tongue reaching into Lake Alida near Foulk Fjord. Named for the 16th-century Native American leader Hiawatha, the glacier later drew wide attention in 2018 when researchers identified a large crater-like structure buried beneath nearby ice. Radar surveys found a bedrock feature about 31 kilometers wide, and sediments from the area contained shocked quartz and melt rock consistent with a major impact dated to about 57.99 million years ago. A 1952 publication had also reported the glacier retreating since 1920.
