Mars - Viking 1 Orbiter

Pedestal craters in the Martian northern plains

Mars
Viking 1 Orbiter image showing a number of pedestal craters on Mars. The size of the pedestal, or raised area surrounding the crater, is proportional to the size of the crater. The mechanism of the formation is poorly understood. North is at 1:30 in this image, which is about 75 km wide. (Viking Orbiter image 043A04)
