Reply to comment by CrustalTrudger in South-west Astrakhan, Russia, has some interesting geographical features I've never seen before. Is there a name for this phenomenon, and how is it formed? by zyphelion

At least when viewed on google maps, they look a lot like the Scab Lands in Washington State. They were also created by monumental floods.

None of the explanations for these features as summarized in the Badyukova paper cited in the original answer focus on megafloods like those that generated the scablands as a possible origin. Ultimately, with many geomorphic features, shape alone is not diagnostic for the formation mechanism.
