It is UTM zone 13 N, using the NAD27 datum. The ellipsoid is
clark66 and the datum transform grid is "conus".

The matching epsg code is #26713, although that code does not
specify which datum transform terms/grid should be used.

As far as I know the Spearfish dataset predates the EPSG
list, or at least they are about the same age.
