Also, there are no S4 sea or deep sea sites. Chris, what S4 site do you think can exist in seas? Or N3? or F4?

Highest site level in seas from Edi's DB:
Non-unique: E3, A3, W3, S3, F1, H1, N1, D1
Unique: N2, D2

(There are S3/?3 unique deep sea sites, but it's irrelevant, because there is also a non-unique site at the same path level.)

Highest site level in deep seas (including "seas"):
Non-unique: E3, A3, W3, S3, F1, H1, N1, D1
Unique: N2, D2

I'll get back to you on it vfb; I took the 3.17 db., sorted on terrain; then by gem type; then by lvl. I'll look back into it when I get home. I had forgotten your excellent post.

How did you determine that deep seas also share the seas tag?
If so, this would mean deep sea sites have almost twice the variety of sites possible - and many more uniques.
