Distinctive Brightness

This full-resolution image is centered on a bright deposit at the end of a gully channel. The bright deposit does not seem to be present in an image acquired several years earlier than 2009, and is likely to be very recent based on its distinctive brightness. The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 25.4 centimeters (10 inches) per pixel (with 1 x 1 binning); objects on the order of 76 centimeters (29.9 inches) across are resolved.] North is up. http://photojournal.jpl.nasa.gov/catalog/PIA21574
