Wow, five miles deep! How did it form? That's what I'm asking.
The only thing that makes sense to me, is that the planet ripped open at that location. I can't see any other way for that feature to form.
Something along the lines of a rift valley. It would be evidence of ancient tectonic activity on Mars if that's correct.

There doesn’t appear to be any outlet, so erosion
would seem to be out. Would love to see some oblique
close ups. Mars, temporarily shut down due to close
of government offices...

"Something along the lines of a rift valley. It would be evidence of ancient tectonic activity on Mars if that's correct." It's just north of the "Valles Marineris," one of the largest rift systems in the solar system. I would bet they were formed at the same time.
