A Textured Mesa
ESP_033564_1405  Science Theme: Landscape Evolution
Also imaged by MRO’s Context Camera, this observation shows one of two odd, rounded mesas with a knobby/pitted texture.

This mesa may be the last remnants of a formerly more extensive geologic unit. Given the particular pitted texture, this formation could be ice-rich.

High resolution images can greatly help to characterize the surface texture and allow us to compare other mid-latitude-type landforms, which may have some connection with ice and sublimation degradation processes.
