That’s a very good observation, but dry lake beds tends to be asymmetrical, whereas the arctic landforms are much more symmetrical. Of course, we are talking about a completely environment than has ever been present on our planet.

Dry lakes present their appearance on the shrinking of the surface material, wheres the tundra landscape occurs from an expansion of surface and just sub-surface features by expansion of ice wedges formation.

Yeah, they tend to be more irregular, but not always, for example here is a dry lake bed that is almost hexagonal:

So I think the conditions affect the geometry. If I had to guess, the quicker they dry out, the more irregular they will probably be. Just a hunch.
