Depending on which part of the Western U.S. you're interested in, you may
be able to get it from the USGS sites mentioned previously as large scale
digital line graphs in SDTS format. Coverage varies considerably by state.  
I think that New Mexico, for instance, is completely covered.  Texas
(which is western in some peoples books) is maybe 50% covered.
