The depth of the entire fjord is -14m. At the junction of the squares, the depth decreases to -1m. But I can't see the wall...
I don't see it underwater, above water, or on the map. The relief itself looks normal, but the stones and algae are
almost "above" the water. I understand what you mean when you write about the wall, I had similar cases.
This really happened in those places where there was a mismatch between the shade and the bordering area.
Square E009N057 does not have different shades like its neighbors. They are all the same color.
There is something different here... I liked the depth effect going up to -1 but it would be a pity if I had to refuse
away from Limfjord because of this problem...
