Might be a good place to land a base--easy to cover over--water right there.

Perhaps, but where are you seeing that water is available? The ice in the image is frozen CO2.

It's is pretty how frozen CO2 sublimates in perfect circles as described as swiss cheese. Same with the circular "pit" which looks like it has ice at the bottom.

There may be water below that--one can hope.
