thanks John. i found a link on that site to
the national atlas, http://www.nationalatlas.gov/
which has a mapping program with mundane layers,
though they did have 'magnetic fields' of the
geological/geomagnetism of the earth, so i made
a map of the state of minnesota with these and
some (asteroid?) 'impact' events, atop the geo-
logical map, all the lines are magnetic fields,
a hidden 'feng-shui'-like EM landscape that is
of potential concern for building context as
more and more becomes tied into this landscape,
and to balance with it. a space surge, wonder if
it could send an EM tsunami through the geomag-
netic landscape and wipe out all artifice in
one fell swoop, as with e-bombs and EMP, etc.
in any case, i love this stuff... thanks.
