The official story on the maps from the 1600s depicting California as an island is that they were intentionally drawn improperly in order to fool people curious about the area. They must have been talking about us.
But they’re not fooling anyone. How could it be on so many maps if that isn’t how it was? Why did a king have to declare that California is not an island? Were it never, would it have to be declared not? I think not.
Again, who knows how much of the Sacrament-o area is actually reclaimed swampland, if any at all. But judging by how quickly water rises around it after a tiny rain, I wouldn’t want to see what it looks like in a real storm. That River swells quick.
