The problem is that you have used an ESRI style file directly under the
mistaken impression that it is compatible with GDAL/OGR.  ESRI uses a
variation of the the WKT coordinate system format.

gdalwarp -s_srs utm10n.prj -t_srs ESRI::spwasth.prj \
   -co "TFW=YES" ortho_imagery/ortho_1-1_1n_s_wa033_2009_1.tif foo.tif

The ESRI:: prefix before the filename tells GDAL/OGR to convert from
ESRI format into "normal" WKT.
