      Process_Description: 50-meter DEM quadrangles for the mexico side of 
                           the San Pedro were resampled to 30-meter. 30-meter
                           DEM quadrangles were mapjoined, then original extent
                           was clipped to SP boundary. The DEM was filled and
                           the flow direction grid was created using the 
                           Arc flow direction command.
