I'm not exactly sure what you are doing, but here is the sequence for  
viewing a map in GRASS

1. Start GRASS
2. Select GIS data folder (optional if already selected)
3. Select project location (determined by projection) in the left-hand  
window (you can create a new one, but don't need to for Spearfish).  
Just pick the Spearfish60 location in this case.
4. Select mapset (where your maps actually live) in the right-hand  
window (you can make a new empty one)
5. Press the "Enter GRASS" button
6. In the GIS Manager, add a raster (or vector or other) layer by  
clicking a button on the toolbar. (Note that there is mouseover help  
for all buttons)
7. In the raster layer properties panel (in GIS Manager), select a  
raster map to display in that layer (use the browse button to the left  
of the entry field).
8. In the Map Display, press the display button (left end of the  
toolbar).

If you still don't see anything, you may need to set your  
"region" (i.e., the 'window on the world' that determines what you  
actually see and work with) to match your map. Use the region setting  
menu button on the Map Display toolbar (icon is a map with a tiny  
magnifying glass) and select zoom to selected map.

Please look at the GRASS manual, the startup help (button on startup  
screen), the GIS Manager help (under help menu), and help for each  
layer type (button on properties panel).
