We were "slashdotted" yesterday(i.e. someone posted an article
about the DCP on slashdot.org), which has caused higher than
normal server loads.

Of course those should be:
Latitude: N48d59m57.110s
Longitude: W117d01m56.715s

The International Boundary Commission(IBC) website has
both NAD83 and NAD27 coordinates for the boundary markers.
Note that the NAD27 ones are listed as being official, while
the NAD83 coordinates have been derived by software.
I have sent an email to the IBC asking what version of NAD27
they have used, but haven't yet received an answer.
I assumed NAD27 CONUS.
