The topish middle where there are a bunch of squares in the water was a sunken city. I sorta made a reference to it in the new spi.
the largish island on the bottom leftish was a large military facility.
middle right was an amusement park, top middle was a large park by a city, and just under that was a town which had a large walled off city (it was quarantined)
Top left in those rocks was a secret-ish facility that had a ufo crash inside it.
The mountain in the middle was showcased in THIS video. (or well the train tunnel through it.)
lets see… I think it got corrupted around the time hawaii came out, but Im not sure, as those ships on the beach on the bottom right were those rusted out warships… though Im also positive this got corrupted long before Hawaii, so Im not sure.
