Image Mission Elapsed Time (MET): 223615476 Image ID: 716372 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Center Latitude: 27.24° Center Longitude: 301.0° E Resolution: 19 meters/pixel Scale: This image is about 20 km (12 mi.) across. Incidence Angle: 62.4° Emission Angle: 0.5° Phase Angle: 61.8°

Of Interest: This surface, located around the central peak ring of the crater Praxiteles, exhibits the effects that both hollows and pyroclastic deposits can have on pre-existing features. The peak ring (located to the left of this image) can be thought of as being eroded or depressed from the combination of such features. Pyroclastic deposits disturb surface material through volcanic-like events, and hollows are believed to be caused by the sublimation of volatiles, which release sub-surface material and depress the surface even further.

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.
