Ridged Margin of Elevated Plateau North/West of Pavonis Mons (possible True Colors; credits: Lunar Explorer Italia)

Snaking across this observation is a ridged margin that appears as though it separates two parts of a canvas.
On closer examination (see the edm), 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 of the Peacock".
