HiPOD Monday, 7 Jun 2021: A Potential Inverted Crater in Arabia Terra

This image shows a possible inverted palaeolake at the end of a long, sinous inverted ridge, which might have formerly been a channel. These channels are similar to others in the region, including Aram Dorsum, a candidate ExoMars landing site. Did the paleolake form within the crater?

How else would you get those distinct lines around the inner perimeter of the craters? They are not circular, so it's not uplift from the impact.
