$ gdalinfo --formats | grep USGS
  DOQ1 (ro): USGS DOQ (Old Style)
  DOQ2 (ro): USGS DOQ (New Style)
  ISIS3 (ro): USGS Astrogeology ISIS cube (Version 3)
  ISIS2 (ro): USGS Astrogeology ISIS cube (Version 2)
  USGSDEM (rw): USGS Optional ASCII DEM (and CDED)

(see gdal.org)

hopefully you want USGSDEM? if so import to GRASS with v.in.e00 and
do what you have to do to get into raster format before running
"r.out.gdal format=USGSDEM". what is the nature of the e00 file?
contour lines? TIN? points? ascii-grid of some sort?
