Ridged Margin of Elevated Plateau Northwest of Pavonis Mons
Ridged Margin of Elevated Plateau Northwest of Pavonis Mons
PSP_009356_1835  Science Theme: Tectonic Processes
Snaking across this observation is a ridged margin that in the enchanced color version, appears as though it separates two parts of a canvas.

On closer examination, it almost looks as though there is a relatively smooth landscape on the left, and pockmarked terrain on the right.

The ridge itself is revealed in incredible detail with what appear to be "gulley-esque" grooves running its length.

Pavonis Mons is part of what is called Tharsis Montes, being the middle of three volcanoes in this region. The name "Pavonis Mons" itself is Latin for "Mount Peacock."
