No that didn't work. The actual data is not in degrees.  I think its in meters of some sort, but not sure which
one.  My fear is that its more than one SRID like it's a set of UTM ones and so I would have to change my SRID for
each slice as the UTM zone changes.

I didn't see any metadata so I'd guess 4267 (longlat NAD27) or maybe
4269 (longlat NAD83).
