- Researchers have written and speculated about glacier-flour dust storms in Greenland for a long time. But it took until this September for investigators to spot such a massive plume of the elusive dust forming and drifting 80 miles (130 kilometers) northwest of the far-northern village of Ittoqqortoormiit.
- Glacier flour is a fine dust created when glaciers pulverize rocks,NASA wrote. While satellites had occasionally spotted smaller storms of the stuff, this one was “by far the largest.” The flour storm formed when a summer floodplain in the region dried out with late September’s colder weather, leaving behind a large deposit of sediment carried south from more-northern glaciers. NASA satellites watched the floodplain become grayer and grayer as it dried out then plume form when strong winds swept through the area on Sept. 29, 2018.
