A Scarp in the Arabia Region

Pictured here appears to be the edge of a blast radius of a large meteorite impact crater with smaller and more recent cratering interrupting its circumference. High resolution can help determine if this is indeed a crater wall or the result of past tectonics. The implications of this being a crater would be the fact that an older, larger impact could be one of the events that caused a global catastrophic disruption in the tectonics and atmosphere.
