   I could have sworn someone had geographical displacement maps...
  I remember seeing one online for Utah that was perfect. It was based on satelite data, grayscale, with the high points being white, and the lowpoints being black.Does anyone know where that might be? 
  did you try vTerrain? ;  Thanks, that site has some good stuff. So far I''ve only been able to find relief maps, I''m not sure why the USGS doesn''t have a grayscale "elevation" map viewer. Maybe they do. I''m still looking.
