This image was acquired by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter on April 18, 2017, at 14:04 local Mars time. It reminded the HiRISE team of the rugged and open terrain of a stark shore-line, perhaps of the British Isles. via NASA ift.tt/2rGyUke
