Booty Battle

While on a cruise ship in international waters, it had to dock on a small island for repairs. The captain was very hesitant to let passengers off the boat and onto the strange island. While wasting time and exploring, your group stumbles across an old pirate tent camp. From the looks of it, they died of an unknown cause. Wait! Is that a map? The treasure is close. First to find it keeps it (maritime law), but you better hurry if you want to make it onto the ship which leaves in 35-40 minutes!
