Select:

 -->  3.  Search All Graphics Information <?>

And search for:

usgs


And you'll find out some information about USGS data availability.

Now select:

   -->  2.  Graphics Software and Data Archives (ftp sites)/

and you might find the following interesting:

   -->  12. Cartographic data - USGS data (Xerox)/

   -->  42. Mapgen/Plotgen and more (USGS)/

   -->  68. USGS Weekly Seismicity Reports (including maps - GIF)/

   -->  68. USGS Earth Science Data Directory/
             (This actually is a database of available data - search
              it for terrain - could prove quite useful.)

One other place to look is only available by anonymous ftp at
the moment - 

US Geological Survey Maps  -  isdres.er.usgs.gov (130.11.48.2).


If you've never heard of gopher don't worry it's free and on the net,
write me a note if you'd like information on how to get started.


Best of luck,
