Scarps Confined to Crater Floors - High Resolution

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,
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.
