Don't the red marked tiles reveal land tiles presence to the south. Also, as (mabraham ?) mentioned, the water tiles coloration implies the same thing.
Apart from the coloration, what about those tiles makes you think they reveal land? We saw them when our warrior was at the various extremities of our land. Land beyond sea has no effect on whether we can see tiles.
I was considering which tile has to be settled in order to get the "culture bridge". I guess any of the two?
I also marked the peak Shulec found.
Either, with a border pop. That suggests settling on the hill if the clams is not already in the set of worked tiles of a marble city, since we'll want a fast border pop to get both the seafood anyway.
