Those rings - don't think waterlines, the topography doesn't work - it's on a slope. Think instead: a very ancient crater rim that has had multiple layers of sediment (ejecta, windblown sand or dust, volcanic ash, etc.) deposited, cemented by fluctuating ground waters, and then differentially eroded. We see the end product of multiple depositional and erosional events.

This sounds sensible, with the caveat that slopes may be historically variable. You're almost certainly correct, though with the presence of groundwater presumed historically in the region where Oppy has heretofore traversed, and with (at least the interior of) Endeavour being dramatically lower, I would hesitate to definitively rule-out surface water until we get some on-the-ground verification. Aside from that, I'm still really intrigued by the Wedge.
