Where can I look up coordinates I've found?
In an Atlas. The location is near Monclova, in Mexico .
Google Maps. BUT - Put in the Latitude First then the Longitude. That location is in Mexico. In the Desert, not close to anything. There is a Farm close by, but no name on it. The closest small town is Santa Teresa de Sofia Update. You made a mistake with the numbers for seconds you put in a comma instead of a period. Google Maps will not accept it that way.
