East Antarctica Surface Melt - Meteor Crater/Lake
« on: January 27, 2015, 08:40:36 PM »
It turns out that the recent satellite image of a potential meteor crater was actually a melt lake that recently drained.

The ring of sunken ice, nearly 2 miles (3 kilometers) wide, was spotted a few days before Christmas on the Roi Baudoin Ice Shelf in East Antarctica, north of Belgium's Princess Elisabeth research station.

The collapsed circles of ice commonly appear in West Antarctica and Greenland, where prodigious surface melting results in scores of lakes, but ice dolines aren't widely known even among glaciologists.
