Appearance in the rap battle
This is the location where Christopher Columbus rapped and also where Spock and Hikaru Sulu make their cameo appearances trying to attack Columbus, which results in Spock being neck-chopped and Sulu being stabbed. There is an ongoing thunderstorm during the battle. The shore featured is most likely the shore of San Salvador, where Columbus' ship, the Santa María, first landed in the new world.
