it is faced with watching its beautiful but outsized architectural resources decay. Ironically,
a town that invested less in large-scale improvements might be better able to reuse and
sustain infrastructure after the mining collapse.
Approaching Ajo from the southeast, an astonishing geological formation appears out
of the desert. Dead flat on top, monolithic gray brown except for a peculiar white layer, it
stretches for miles, completely hiding the townsite from view. This is the spoil dump from
the mine. An entire mountain, in effect, has been exported onto the desert.
