Reminds me alot of an archeological site... they will sometimes build a structure over a large or important site to protect it from the elements
(sandstorms in this case...). I know that there are a large number of archeological sites w/in the city of Phoenix itself...maybe this is one of
them.
BTW, heres a photo...someone said they thought it was a wastewater treatment plant....I don't think so, doesn't look like one. The fencing around it
is more construction site type fencing, and there is no real infrastructure.
