Ridges In Cydonia Mensae On Mars
Cydonia Mensae

A ridge stands prominent in this scene, left behind as the surroundings were eroded, perhaps marking inverted erosion of an ancient fluvial channel.

The ridge is made of material more resistant to erosion and, considering the craters on its flanks, was formed long ago.

Erosion continues to this day: boulders that have fallen from the ridge are evident, scattered along the sides. Sand has begun to form small dunes adjacent to the ridge.
