The goal of this observation from NASA' Mars Reconnaissance Orbiter (MRO) is to determine the source of the ridge within a possible moraine that is also present in another HiRISE image. A moraine is a mass of rocks and sediment carried down and deposited by a glacier. If the structure is a moraine, we should expect to find two sources of debris converging in the valley. If the sources are carrying lots of debris, there is a good chance of finding more moraine features further up the valley. The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 59.5 centimeters (23.4 inches) per pixel (with 2 x 2 binning); objects on the order of 179 centimeters (70.5 inches) across are resolved.] North is up. https://photojournal.jpl.nasa.gov/catalog/PIA22124
