September, 2009 satellite images released by NASA's Earth Observatory.

This satellite image shows several small glaciers spilling into a mostly dry valley in western Greenland. The image was captured on August 29, 2009. The Advanced Land Imager on NASA’s Earth Observing-1 satellite acquired this natural-color image. This image shows most of the valley and the image below is a close-up of two glacier snouts.

Image Information:

Multiple glaciers frequently flow into straight valleys in Greenland. The valleys result from earlier glaciations that carved the bedrock. The smaller glaciers that flow into the valley may take advantage of weak joints in the bedrock.
