Reticulate Terrain (Mars, Hellas), Fig. 1
An example of reticulate terrain which can be seen in NW Hellas. The terrain displays erosive behavior with rectilinear ridges that can be an inverted terrain displaying older and more resilient crack fillings. The overall magnitude, orientation, and erosive behavior argue against them being fossilized dunes (El Maarry et al. 2012). Direction of sunlight is from the upper left.
