I am trying to add a projection for a shapefile with no GCS or Proj. I used Define Projection (I picked GCS_North_American_1983_CSRS) first, followed by Project (NAD_1983_CSRS_UTM_Zone_20N). This matches my other shapefiles projections and data frame as well. My result shapefile is nowhere near the rest of my data. Could I be missing something very simple here?
