It would still be interesting to read you criteria else it's of no use to only say so.
Can you show the whole map or at least the date?
Hi Bocaj,
You can find a short list of my island criteria on post #95.
The map that I referenced was published by Johnson in 1868.
(Re: Magnetic Declination)
The magnetic declination in a given area may change slowly over time, possibly 2 to 2.5 degrees every hundred years or so, depending on where it is measured.
This may be insignificant to most travelers, but can be important if using magnetic bearings from old charts.
