NASA Rift on Pine Island Glacier

A new iceberg calved from Pine Island Glacier—one of the main outlets where ice from the interior of the West Antarctic Ice Sheet flows into the ocean. The Operational Land Imager (OLI) on the Landsat 8 satellite captured this natural-color image on September 21, 2017, just before the break. via NASA http://www.nasa.gov/image-feature/rift-on-pine-island-glacier
