Treasurrrrrrre Traditional Geocache

We've hidden this treasure on the island, so you'll have to cross the narrow sea to find it. Look over, look under, the treasure is safe from thunder. We've left the island and headed south west. So follow our way if you want your pay.

Argh! We are pirates and we've hidden our treasure box! You'll have to do some searching if you want to find it. With no sand, we've had to settle for hiding it under some local vegetation. We are headed south west after burying our treasure.
