Roger around the World

Still in the Halong Bay and can't get the pirate thoughts out of my mind.

This one is obvious; Can you see the half-skull?

This mystery is easily solved. On the pirate Captain Henry Morgan's birthday, at three o'clock in the afternoon, see where the sun shines through the eye and there will be treasure where the sunrays land, be it on the shore or in the water.

Or maybe it's where the sun lands plus nine steps to the east and nine to the west?

Be prepared and bring extra many shovels fo good quality if you decide to try this one...
