13 Ancient Sites in Arizona That Still Don't Make Sense

Arizona is not empty. Beneath the interstate exits and retirement communities, there are structures older than the pyramids, canals that modern Phoenix still uses, cliff apartments ninety feet off the ground, and a four-story building nobody ever lived in.
