These coordinates are now mostly verified and/or recorded off my GPS12. Datum NAD83 and WGS84 were interchanged, however in North America the two differ by less than 2 meters, so no worries. I've now set my unit to WGS84 as it should be on this standard for GPS. Obviously some of these items are vague, such as Helen, or the Heart. But if you think one is grossly off, please mail me using the comment form.
