If by coordinates you mean township, section & range of a meridian, you
may wish to locate what the USGS used to call a baseline map of whatever
state your specs are located. I have never attempted to find one of these
online, but I used to purchase these state "baseline" maps from USGS a long time
ago in order to locate land in public domain states.

OK, so how about this (keep in mind that I have not one clue what I am
doing here, just want to find out where the land was from the
coordinates given and knowing what state it was in). I have GPS on my
phone. Is it possible to enter the township, range, section,
meridian and get a GPS map (I have a G1 phone featuring Google
applications)? And can you even do that with a phone (I can't find
the user's manual when I need it)?
