You can see what they look like in GR by looking at this and this. If you would like to download these background images, you can get the color version here and the black and white version here.

To install, you will need to:

1. Start GR
2. Click on “GIS” in the menu across the top
3. Click on “Setting” in the resulting drop-down menu
4. Click on “Backgrounds…” in the resulting drop-down menu
5. Select the file you downloaded. (You will need to unzip the zip file if you haven’t already.)
6. Enter the longitude and latitude values for the various corners. These are:
   • Left Lon: -125.
   • Right Lon: -63.
   • Bottom Lat: 22.5
   • Top Lat: 50.
7. Select “OK”
