Hi patch, just picked it up again.
Forgot I had it in my pile.
Have only few answers so not as far as you are.
If I get the grid done, I will be back.
If I crack 3d and 8d, I can make progress.
Looks tough.
Hi patch49; might it be 6 letters that don't form a word in itself but sound like a synonym of 1 of the features that when viewed with the other 13 provide a rough map/outline. DEEERE sounds like dear ?
Hi sunray, yes. I was sent this puzzle by syzygy, I don't normally do these so my comment re the additional 6 is most likely best ignored as I'm not really certain what that part of the preamble means.
