Today’s Image of the Day comes from the NASA Earth Observatory and features a look at the Ga’ara Depression in Iraq.

The Ga’ara Depression is an oval basin located near the Iraq-Syria border that formed from alternating layers of sandstone and claystone about 300 million years ago. Then, layers of carbonate rock, including dolomite, marl, and limestone, coated the foundation.

This image was captured by the Operational Land Imager (OLI) on board the Landsat 8 satellite using shortwave infrared, near infrared, and green light to distinguish the different rock and soil types.
