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.
