FIG. 4.

Examples of faults and fractures on Mars that could enhance seepage from deep, major faults (e.g., Fig. 2B) or those associated with large impacts (e.g., Fig. 6). (A) High Resolution Imaging Science Experiment (HiRISE) image illustrating multiple fractures and faults in megabreccia in Nili Fossae. Arrows point to examples. (B) HiRISE image of faults in dunes in Danielson Crater, Arabia Terra. Arrows indicate relative displacements. (C) Context Camera (CTX) image of fractures that define the boundaries of some of the giant polygons in Utopia. Centerpoints: (A) 19.37°N, 76.48°E; (B) 8.09°N, 353.18°E; (C) 35.89°N, 103.86°E.
