Mariner 4 Image of the Area between Elysium and Amazonis Planitia on Mars

Mariner 4 image of the area at the border of Elysium Planitia and Amazonis Planitia. This picture was taken from 9,900 miles (16,000 km) and is about 311 miles (500 km) across and 560 miles (900 km) from top to bottom because the surface is curving away. The sun is illuminating the area from the southeast.
