Caption:

The scarp in this 35-kilometer crater (See PIA02433 for the location in a larger view) forms a broad lobe 10 kilometers wide, whose southern end abuts against and follows closely the irregular contour of the crater wall. These structural relations suggest the scarp is a flow front rather than a fault.

This image (FDS 27471) was taken by Mariner 10 during its first encounter with Mercury,

Background Info:

The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon.
