We know that Mercury's surface is heavily tectonized , but we don't always get to see features like lobate scarps up close. This example, located within a smooth plains deposit near the equator, has a total length of about 120 km (75 miles) but is only on the order of a couple of hundred meters in relief. Numerous impact craters dot the scene, including some that superpose the scarp face itself.
This image was acquired as a high-resolution targeted observation. Targeted observations are images of a small area on Mercury's surface at resolutions much higher than the 200-meter/pixel morphology base map. It is not possible to cover all of Mercury's surface at this high resolution, but typically several areas of high scientific interest are imaged in this mode each week.

The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet. During the first two years of orbital operations, MESSENGER acquired over 150,000 images and extensive other data sets. MESSENGER is capable of continuing orbital operations until early 2015.
