I'm not sure how the Hab didn't find it's way to Arizona. It wasn't because Arizona didn't look the part or lacked the correct morphology.

I've had the pleasure of visiting the northwest corner of Az, Kingman area, Bullhead City and Lake Havasu City and parts of that area looks exactly like Pathfinders Landing site. The desert southwest is a beautifull part of the Americas, well worth a visit!

There was long list of requirements for the site and something need for the final site wasn't at the AZ sites on the list. But they got rejected very late in the process very nearly becoming the final site. The areas here in Washington State were cut earlier because we have to much vegetation with the irrigation and limited areas to roam do to the large military and nuclear reservations. Still, we may be working the Channeled Scablands as a model of a rover mission far from base, but that has to be looked at logistically still.
