[Aztlan] Maya ruins found from space photo

[Greg Sandor]

Just off the top of my head (and before my coffee is ready, so I request
permisssion to revise and extend):

I recall reading a paper from China a couple of years ago about gold
prospecting by this method.  It seems there are indicator minerals near gold
deposits, which are absorbed into plants, which presents a distinct
signature.

Compacted soil and difference in density of vegetation on footpaths reflects
heat differently than undisturbed soil and show up in IR photos.



Regards,

Greg
