But I think this explains why some outfits prefer Lat Lon.

Yes, but even with Lat/Lon, you still need to specify the datum. For example N 61 deg 12.047 min W 149 deg 56.712 min in NAD83 is about 134 meters WNW of the same Lat/Lon in NAD27. The reason is that each is referenced to a different spheroid.

No worries. I have good friends who are archaeologists. I'd leave it for them. I'm a geo, and more interested in what's underneath. There is an old saying in geology: "One man's overburden is another man's basement!" smile wink
