     For many decades there have been many discussions about whether or not major ore deposits in the
western portion of North America occur along preferred lines or lineaments.
     This easy to test using Google Earth.

map of open pit mines and major mining areas as related to the State of Arizona

     Most of the mines fall upon a small number of straight lines.  Something does tie the ore deposits to
linear structures.

     Here is an oblique view of the linears and the mines.  This map strongly suggests where there might
be other hidden ore deposits and where one should start looking.

     Here is a closer view of southeastern Arizona.  Included in this view is Bisbee, Tombstone, Tucson area
copper mines, Cananea, Zacatecas,
Globe, Miami, Ajo, etc.

Lines on these maps were drawn using the measuring tool that comes with Google Earth along with
a large selection of icons.  Views of the planet can also be tipped at various angles to obtain oblique views.
